Apple: iPad 3 battery gauge works as expected

Summary: Apple didn’t want to show the iPad battery constantly fluctuating between 90 and 100 percent as the battery goes through its normal trickle charge/discharge cycle to keep it topped off.
Apple: iPad 3 battery gauge works as expected - Jason O'Grady
AllThingsD’s Ina Fried published an article today indicating that the observations of unusual charing behavior with the iPad 3 aren’t so unusual after all.
Yesterday I noted that if you unplug your iPad 3 as soon as the iPad 2 Foldable Leather Case Built-in Bluetooth Keyboard + Battery indicator says “100%” you’re actually missing out on as much as 1.2 hours (10 percent) of additional run time. But Apple says that this is the expected behavior and that the iPad battery is designed to work this way.
Fried explains it this way:
Apple does, in fact, display the iPad (and iPhone and iPod Touch) as 100 percent charged just before a device reaches a completely charged state. At that point, it will continue charging to 100 percent, then discharge a bit and charge back up to 100 percent, repeating that process until the device is unplugged.
Soneira, President of DisplayMate Technologies Corporation, first discovered that the iPad 3 experienced a net loss of 1.2 hours (around 10 percent) of Folding Solar Panel Charger with 45Wh Solar battery run time if unplugged as soon as its battery indicator displayed 100%. His essential point was that if the iPad 3 is fully charged (i.e. overnight) it will run 11.6 hours, which is 1.2 hours longer than if it is only charged to 100% (10.4 hours).
Apple VP Michael Tchao tells AllThingsD that Apple decided not to keep changing the battery status “so as not to distract or confuse users,” explaining:
That circuitry is designed so you can keep your device plugged in as long as you would like, It’s a great feature that’s always been in iOS.
So there you have it. The iPad battery displays “100%” a little prematurely because Apple didn’t think that it would be wise to show the lenovo thinkpad l512 battery constantly fluctuating between 90 and 100 percent as the battery goes through its normal trickle charge/discharge cycle to keep it topped off. Makes sense to me.

When my New Ipad reaches 0% it's dead and I need to charge it. That's pretty much the bottom line for me. I'm more concerned with when they're going to put the rest of SIRI in the Ipad 3 (yes, I said Ipad 3). Don't make me wait until the next IOS comes out, send a patch first. Show Less -
 
 How many articles are going to be written about this very James Quinn 1 day ago
"smallish" issue!?! Is Apple so good at what it does that ever none events that might point to a very slight problem become (what is it now) 6 articles worth on ZDNet? If so I guess that's kind of good news:)

All that article did was rehash half of Jason's first article on the Dell XPS M1210 AC Adapter battery issue... but if you want to accept that as fact and be wrong yet again go for it.

Don't you get tired of being wrong all the time and displaying that fact every single time you make a post here?
You have a weak grasp on what the concept of "proven" means

"Proven" does not mean what you think it means. For one thing, it involves "proof" not just unfounded supposition.

The iPad's battery works the same as every iOS dell inspiron 9400 ac adapter battery ever has. The iPad is no warmer than other comparable tablets and cooler than most notebooks. LTE eats up data on your iPad...exactly the same as it does with every other LTE device.

Talk about much ado about nothing.

You're STILL talking about the inspiron 1545 Battery. I wish one of the technology giants would release a phone or something so you'd quit your incessant babbling about the stupid iPad 3 battery issue. Which, as many of your posters on the previous stories noted, was a non-issue from the beginning based on standard battery behaviors...

Put down the stick and walk away from the horse Jason...

when you consider the heat and Acer aspire 5552 battery tests run on all the other tablets. Could someone point me to the articles about the array of Android tablets so we can see what happens to those tablets after they show 100%?

I can't seem to find them.

Look at those results. Apple said up to 10hrs and 90% gets you 10.4. I mean, what bandits! They should have, instead, said up to 11 hr and show the charge and discharge cycles because when people see the hp pavilion tx1000 battery display constant fluctuate between 90% to 100% *surely* we wouldn't see stories about THAT anywhere. "Apple iPad constants charges, increase home power usage .000003%. People outraged!"

have an animated icon that either replaces the charge indicator, or cycles the bars on the existing one.

That way you can tell if it is charging, or if the power connector is not plugged in correctly, or if the PSU is actually plugged into the wall.

Modern devices that use Lithium cells do indeed all have this feature, as it is extremely bad for this type of cell to be overcharged or completely discharged. Overcharging a Radio Control Lithium pack is extremely dangerous as those things can deliver double figures in Watts, and an internal short can get hot enough to cause a fire. Discharging them completely can cause these shorts as crystals grow in the Polymer layer and are repeatedly dissolved by the charging action, weakening the insulation - so the most efficient use of the cell happens above 20%, which is when the device says its empty, even though it is not.

iPad batteries dont hold enough charge to do serious damage, however their life is also shortened by that kind of abuse, hence the aspire one 10.1 battery management system.
Most people are now familiar with the fact that modern batteries need to be treated with a little consideration, and watch their charge cycles accordingly. Its just curious to me that Apple have decided to try and hide this standard behaviour because it might 'confuse' users.

This smacks of treating customers as if they were stupid...

As a professional technology consultant that has worked with all sorts of clients, it will amaze you what will confuse people. I still run into people that are confused by two button mice! (which is why Apple still sets the default to single button operation on Macs, but I digress)

From a usability standpoint, Apple did exactly the right thing. Why add a ibm thinkpad r50p battery charge indicator that may not be immediately obvious what it means? Especially when most users could care less? If the charge indicator shows 100% and you get the specified battery life, why worry about the technical details of battery management? It's nothing users can control or even need to worry about. It's these fine little details that make Apple products the most usable in the world. An engineer might have thought that a different pa3356u-1brs battery indicator would be a great idea, but most people aren't engineers. Just imagine from a technical support standpoint the number of calls that would have been generated by this subtle little change. "My battery charge indicator is freaking out!" This is just another example of Old World vs New World of Technology thinking and why Apple is the company it is today.
If it were designed well, it wouldnt generate tech support calls

Thats the whole point of good design, its clear and simple. Hiding the process has only generated a whole lot more trouble than fixing the problem would have in any case. Its just curious, Apple pride themselves on design, and thats not the best design I've ever seen.

And I still think Apple using the excuse that the users wouldnt understand is a bit insulting, given the capabilities of the device and who it is aimed at...
Merott 11 hrs ago
Really? The battery charge fluctuates by 10%? That's more than an hour's worth of battery charge with the iPad actively in use, and way more than that if it's on standby... I see that as a design flow, they could have made the full-charge window smaller than that! The Acer Aspire 5235 Battery can't be fluctuating by 10%, simply nonsense! Apple is again trying to cover up...

I'm not an Apple hater at all... In fact I own an iMac and I like their other range of products including the iPad, but I think Apple is constantly taking advantage of the lack of knowledge in the average user... Yet, Apple is a business, and that's how you do business!
On My New iPad, The Display Does Not Work As Expected Nor As Before On Previous Models
FutureMedia Updated - 11 hrs ago
The New iPad battery level display certainly does NOT work as expected on mine. Plugged into the New iPad wall charger, when it reaches 100% the display switches to "Not Charging" next to the grey FUJIFILM FinePix Z35 Charger battery icon WITHOUT the black plug icon inside it. Very disconcerting. No way to know if the charging has stopped or not. Apple tech support has never heard of this indication before unless plugged into a computer's low power USB port. Michael Tchao needs to know about this bogus display info ASAP. It's got me wondering what's going on inside my New iPad's battery charging system.

Race Rewind … In March 2011, handling issues plagued the No. 27 Chevrolet team early in the 200-lap race and Menard quickly slipped from his 15th-place starting position. The Slugger Labbe-led team made adjustments during each pit stop in order to neutralize the tight condition that Menard was battling. Buried deep in the field for the restart after the final caution of the day, Menard battled back to the 16th position, where he took the checkered flag and recorded his best finish at the two-mile speedway.
In the Rearview Mirror: Bristol … Starting from the 11th position, Menard and the No. 27 Moen/Menards team emerged unscathed from Sunday’s Food City 500 at Bristol Motor Speedway to finish 10th and earn their third top 10 of the 2012 Sprint Cup Series season.
PAUL MENARD QUOTES:
Last year you finished 16th, but that was still your best finish at Auto Club Speedway. You do so well at intermediate race tracks with solid top-five and top-10 finishes. Why is it that this one has been such a challenge?
“I don’t know. That’s a good question. It changes a lot with the weather, so we find ourselves chasing the weather conditions. One day it might be cold in California and the next day it might be 20 degrees warmer; that changes a lot with the car. I just haven’t quite nailed it yet.”
How would you describe Auto Club Speedway? Is it opening up? Is it more competitive?
“I know that California (Auto Club Speedway) gets knocked as a race track since it is wide open and generally caution free. Drivers tend to enjoy that, though. You have long runs and can really analyze your car and work on it during pit stops. The track is really wide. You can run top to bottom and everywhere in between. It’s relatively smooth, too, and makes for fun racing for us drivers. If a race fan wants to see crashes and cautions, that’s probably not going to happen there.”
The races at Auto Club Speedway typically turn into a fuel mileage race. With the EFI engines changing fuel mileage, do you think you’ve had enough time to get a hand on that and really understand what you have?
“Every track that we go to, Daytona (International Speedway), Bristol (Motor Speedway), California (Auto Club Speedway), it does not matter because it’s a fuel mileage race. It just matters where the cautions fall. EFI isn’t going to change any of that. You might be able to run a lap or two longer in a fuel run, but ever track that we go to will be a fuel mileage race if the cautions fall appropriately.”
Out in Fontana (Calif.) a lot of times celebrities show up – movie stars, television stars and musicians. Have you ever met anyone out there that sticks out as being someone you thought was pretty cool to meet?
“Usually there’s some celebrity at every race track, but in California there are more than normal. I’ve met two people at Auto Club Speedway over the last couple of years that I thought was pretty cool. The first was Christian Slater. That was cool because I was a big fan of his growing up in the early 90′s. The other was Chuck Lidell who is an MMA (mixed martial arts) guy. To watch those guys on TV is crazy. They’re pretty hard core. Then you meet them in person and they’re really nice guys.”

KEVIN HARVICK QUOTES:
What was it like winning on the last lap at Auto Club Speedway last year?
“The last two years, the race has pretty much come down to us and the No. 48 team (Jimmie Johnson). The year before I ran into the wall and last year we won. That was good to come back and rebound from the mistake from 2010 and being able to race with Jimmie was a lot of fun. Especially at the California race track. That’s been a great race track for us over the last several years and looking forward to going back next week. Glad I’m not the truck driver, he has a long ways to go.”
Why are you so good at Auto Club Speedway?
“It’s one of those race tracks that the tires just wear out a lot. You can move around the race track and you have to kind of search for grip so that comes with a lot of throttle control and momentum to go along with that. It’s a race track that fits our cars and our engine package and our driving styles. As a company, we run well there. It’s a good race track for RCR.”
What do you like about Auto Club Speedway?
“I just enjoy how the track has really spread out and the groove you can run from the bottom to the top. It’s also fun to race in front of a lot of your fans and friends that get to come to the race track from close to where we used to live.”
You’re a few races into the season with crew chief Shane Wilson and the team. How are things coming together for you and the new group so far this year?
“I think they’re going really well. I think we definitely have to clean up some of the rough edges from me having a little rust on myself and get the communication exactly where we want it to be as far as the things we want to hear and don’t want to hear and things they want to hear from me. We’ve got a few things to clean up, but I think it’s gone very well so far.”

Points Racing … With his top-10 finish in “Thunder Valley,” Burton currently sits 11th in the Sprint Cup Series driver championship point standings, 37 points behind leader Greg Biffle.
JEFF BURTON QUOTES:
You finished 15th at Auto Club Speedway last season after qualifying seventh. Was that indicative of RCR’s speedway program last year?
“That was, without a doubt, our weakest point. One-and-a-half and two-mile tracks weren’t RCR’s strong point last season. We’ve worked really hard to be better on those tracks. You have to be competitive on these tracks. You can’t expect to go and win the championship if you can’t go to those tracks and run strong. There are just so many of them on the schedule. The interesting thing about Auto Club Speedway is that it’s big, but it races like a short track. There is very low grip. It’s amazing how sideways these cars are in the turns going this fast. Restarts are really important because if you gain a few spots on the restart, it is hard for those guys to come up and pass you under a long green-flag run. You’re going to be three and four-wide on these restarts. You must have good take off speed and good durability with the car. People don’t realize how slick Auto Club Speedway is. It looks like a big track and the cars don’t move around that much, but they are out of control.”
Historically speaking, this race has turned into a fuel-mileage race. Since the track is big and wide, drivers have the skills to stay out of trouble. How are you guys working on fuel mileage with the new EFI engine?
“Fuel mileage appears to be a little bit better with the new EFI engine. You burn less fuel when you are off the throttle with EFI than you did with the carburetor. It’s a little more efficient while you are in the throttle so you are going to get a little better fuel mileage. Of course, that means the whole field is going to get better fuel mileage. The only way that really matters is if you pit at that right time. Now more people will make it unlike before. We saw a few races last year where a lot of people ran out of fuel on the last lap. Now, all of those people would make it. It changes it a little bit, but not really because everyone’s fuel mileage is getting better. What would be great is if we were the only ones to get better fuel mileage, but that’s not the case here. Everyone is getting better fuel mileage.”
What happens if you run out of fuel at a big track like Auto Club Speedway with an EFI engine?
“With an EFI engine, fuel is constantly being pumped throughout the system. Your throttle body is taking the fuel that it needs and distributing it. When you run out of fuel with a carburetor, you have to fill that system back up. The only way to do that is through the engine. You must get the fuel pump running enough to bring that fuel up and once you’re running that doesn’t mean it is going to stay running. You see a lot of people with carburetors run out of gas, get the engine running and then it shuts off again. With EFI, once they plug in and start filling the thing up and you turn the ignition switch on, the pump starts running. You don’t have to have the motor running so the pump is running and pumping fuel. Once you feel that system and the reservoir that’s in the fuel cell, you can start that car. Once you get fuel pressure with fuel injection, you are running off a reservoir that’s inside the fuel cell, you can run and it will stay running. In theory, assuming the battery is good enough, you should have fewer problems as you run out of fuel with EFI than you did with carburetors.”
Are there any potential problems that could bite you badly if you ran out of gas at Auto Club Speedway?
“The biggest issue with an EFI engine is that has to spin to find itself to determine where it is in the spark sequence. If you have power and everything is operating correctly, once it finds its sequence of what cylinder it is supposed to be firing and you have fuel, it’s going to fire up. We have also introduced electronics into a situation where these cars are really hot and have a lot of vibrations. We also have those issues that we didn’t have before. There will be some issues; there always is. Anytime you have something new, there are going to be some issues. We’ve done everything we know how to do, but that doesn’t mean we are going to have problems.”
Brendan Gaughan
No. 33 South Point Hotel & Casino Chevrolet Chevrolet Impala
Event Preview Fact Sheet
This Week’s South Point Hotel & Casino Chevrolet at Auto Club Speedway … Brendan Gaughan will pilot Chassis No. 392 from the Richard Childress Racing NASCAR Sprint Cup Series stable. This Chevrolet Impala was built brand new for the 2012 season and will see its first competitive laps this weekend in the 200-lap event.
Statistically Speaking … Gaughan has two previous Sprint Cup Series starts Auto Club Speedway, both in 2004. He earned one top-10 finish (sixth) and his career-best starting position (fifth) in May 2004.The 36-year-old racer owns an average starting position of 13.5 coupled with a 24th-place average finishing position. Aside from Gaughan’s two Sprint Cup Series starts at the Fontana, Calif., facility, the Las Vegas native has five starts in the Nationwide Series and seven Camping World Truck Series starts at the two-mile race track, where he holds two top-five finishes and a pole award.
Race Rewind: Bristol Motor Speedway … Gaughan started his third Sprint Cup Series race of the season from the 32nd position at Bristol Motor Speedway on Sunday. The Las Vegas native ran in the top 15 for a majority of the first 150 laps around the half-mile bullring but slipped through the field when he reported an issue with the throttle spring. He continued to hold onto the No. 33 South Point Hotel & Casino Chevrolet throughout the remainder of the race earning a 22nd-place finishing position.
Twice the Action … Aside from his Sprint Cup Series responsibilities this weekend at Auto Club Speedway, Gaughan will also pilot the No. 33 South Point Hotel & Casino Chevrolet Nationwide Series Chevrolet for RCR.

Four of Four … This weekend’s 400-mile event will mark Gaughan’s fourth and final scheduled Sprint Cup Series race with RCR. At the beginning of the 2012 Sprint Cup Series season, RCR announced the No. 33 Chevrolet would run the first five events on the schedule. Elliott Sadler kicked off the season driving the No. 33 entry in the Daytona 500 and Gaughan has been behind the wheel for the last four races.
March Madness Update … With only one of Gaughan’s Final Four picks left in the NCAA Men’s Basketball Tournament, the former Georgetown University basketball player cheers on Michigan State University as they head into the Sweet 16. Gaughan originally picked Florida State University, Duke University and Georgetown University as the Final Four teams, but they have since been defeated in the first two rounds of the tournament.
Did You Know … Gaughan is slated to run three trophy truck races for Collins Motorsports this year including the SCORE Baja 500 (May 31-Jun. 3) and Baja 1000 (Nov. 14-17). The Las Vegas native ran the Laughlin Dessert Challenge in January and his team finished in the fourth and sixth-places, respectively. Gaughan grew up racing trophy trucks for Walker Evans Racing touring mainly in southern California.
BRENDAN GAUGHAN QUOTES:
This will be your second double header weekend. Is it more difficult to race both the Nationwide and Sprint Cup Series in the same weekend?
“No, it actually worked into my favor at Las Vegas (Motor Speedway) earlier this month. With all the distractions that were there, it helped me stay focused and only have to concentrate on the race cars. It helped me block everything else out.”
This is your last of four scheduled Sprint Cup races this season with RCR. What are your thought heading into this weekend at Auto Club Speedway?
“I just want to keep improving, this car is totally different than any other NASCAR race car I have raced, so I want to keep improving and end on a high note. I want to score my best finish and improve my driver rating from Bristol Motor Speedway.”
Have you learned anything racing in the Cup Series that can be translated for the rest of the Nationwide Series season?
“Just to stay focused and give the crew chief accurate and quick feedback so he can make his changes and decisions as quick as possible. I’ve had the ability to see how much engineering is available to the RCR crew chiefs, it has made me realize that I have to give them good feedback and give it to them in a timely manner.”

There is a lot of talent on our team, and I think that we are going to continue to remain focused each and every week on the goal of winning this Nationwide Series championship.”
What are your thoughts on Auto Club Speedway?
“I like going out to California to compete at Auto Club Speedway. It’s a neat race track, and it’s very wide and fast. I feel like I ran pretty well there last season with a top-five finish. I feel like we are a little better prepared this season, because we know what kind of setup we need to be able to get there and unload quickly. We have a lot of ECR horsepower, and they just found a little more before we head out there, which is always good news. I was able to win the first-ever night Sprint Cup Series race at Auto Club Speedway back in 2004, so I always look forward to going to California.”

AUSTIN DILLON QUOTES:
Other than not getting to Victory Lane yet, your start to the season is almost as much as you can ask for as a rookie …
“It’s been a very good start to the season. The No. 3 Chevrolet has been good everywhere we have been. We’ve had to work quite a bit in practice to get there, and we’re learning every race. We’re gaining experience as a team and we’re really trying to fight that right now so that we can get to Victory Lane. Once we get comfortable getting to the track and get to the point where our setup is correct so that all we have to do is fine-tune the car during practice, we will be much better. It’s really cool to come out with three top 10s and a 12th-place finish to start the season. Coming from a multi-car operation and being able to lean on the guys with more experience is big for me. Just watching Elliott Sadler and Kevin Harvick and the experience they have driving the newer Nationwide Series cars that the Nationwide means a lot to be able to use their notes and talk to them.”
What kind of transition has it been for you to the Nationwide Series? Has it all been as easy as it looks?
“It’s been a good start. You can’t ask for better luck going into the races. Things have played out for us the right way. We’ve put ourselves in a good position to create our luck. If we can keep doing that throughout the season we will have a shot at the end at Homestead-Miami Speedway. That’s what we’re trying to do. Keep ourselves in a position where we can be there at the end of races and have a shot to win the championship.”
You’ve never race at Auto Club Speedway. Does that worry you?
“I think we’ll be good at Auto Club Speedway. The bigger tracks suit me well. It’s very similar to Michigan International Speedway and I run really well at Michigan. It’s one of my favorite tracks. I can’t wait to get to California. I’ve heard the track is a little rough, but we’ll learn how to adjust our car when we get there. We plan to adjust on the car throughout practice and lean on the teammates. I think how big the tracks are you can really move around and find speed and my dirt background plays to the advantage there. I’ve just always been good at those types of tracks.”
Brendan Gaughan

Lead-Carbon Batteries: Cheap Classic Chemistry With 21st Century Performance

Mark Twain quipped, "It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so."
Truer words were never spoken, particularly when it comes to the Dell inspiron 14r batteries that most of us use and curse on a daily basis. If you have a car, you have a lead-acid starter battery that needs to be replaced every couple years. Cellphones and laptops offer similar trials and tribulations unless you upgrade your electronics regularly. When our cars don't start or our electronics don't work, we invariably blame the batteries first. While most of us haven't noticed any major change in starter battery performance over the last couple decades, the utility of electronics has skyrocketed and many believe the gains come from improved battery performance. They're dead wrong.
Today's car Dell inspiron 1545 batteries aren't terribly different from the ones we bought in the '80s and '90s and they don't perform any better or worse. We just demand more from them as we add increasingly sophisticated entertainment, passenger comfort, information and fuel economy systems to passenger cars. The same is true for the batteries we use in portable electronics. NiMH batteries performed better than NiCd batteries that were plagued by memory effects. Lithium-ion performed even better than NiMH. Within each chemistry class however, today's batteries aren't terribly different from from the ones we bought years ago. The only truly major improvements have been longer cycle-lives – the number of times a battery can be charged and discharged before it needs to be replaced. When you cut through the fog of errant assumptions and get down to facts, the reason electronic devices work better is that clever manufacturers have found ways to slash energy use by 80 to 90 percent while increasing functionality. It has absolutely nothing to do with improving the performance of a particular chemistry.

A popular French phrase aptly describes technical progress in the battery for Dell Latitude D630 industry – "plus ça change, plus c'est la même chose," or the more it changes, the more it’s the same thing. The following table summarizes the development history and typical specific energy of today's leading battery chemistries.

Two key takeaways are (1) the long periods between the invention and the commercialization of new battery chemistries, and (2) the slow incremental nature of progress in the battery industry. Despite a never-ending stream of optimistic press releases, no major new xps m1210 battery chemistry has entered the market since the launch of lithium iron phosphate in 1996.

For those who've gotten used to Moore's Law, cumulative gains of 1% a year over 153 years are not impressive. I read the same stories as everyone else and know all about the researchers who boldly promise to double or triple energy density by the end of the decade. I also understand the difference between hope and accomplishment. My inner geek will wildly cheer new developments if, as and when they prove their technical and economic merit in a free market. But my inner investor will never forget that hope is not an investment strategy and results are the only things that count.

Brief history lesson

Like all mature technologies, batteries have progressed through several evolutionary cycles over the last century as users' needs changed. Until the '60s, the two dominant classes of batteries were rechargeable lead-acid batteries and disposable dry cells. Lead-acid batteries did the heavy work like starting cars, powering equipment and providing emergency backup power while dry cells powered flashlights, toys and consumer goods, including the first wave of portable electronics.

In the early '70s a variety of low-maintenance flooded lead-acid batteries and high-performance AGM batteries were introduced. They rapidly became industry standards. They worked so well that R&D in the lead-acid battery sector plummeted because there was no need for better lead-acid batteries and the perceived value of additional refinements didn't justify the added cost. About the same time, Japanese manufacturers launched a wave of portable electronic devices that desperately needed better Acer aspire one 10.1 battery. So R&D spending on lightweight rechargeable chemistries soared. That trend continued through the turn of the millennium because lead-acid batteries were good enough for the work they performed while batteries for portable electronics were grossly inadequate.

Since the turn of the millennium, a new market dynamic has emerged that's driving unprecedented levels of R&D in the fields of electrochemical and physical energy storage. The primary requirements of this new dynamic are cost-effective systems that store massive amounts of energy, need little or no maintenance and deliver peak performance for a decade or longer. It's a tall order when you understand that most of the batteries we used in the past were designed for devices that needed tiny amounts of stored energy and had short replacement and upgrade cycles.

For lithium-ion Dell XPS M1330  battery developers, the principal technical challenges included:

Making cells that were designed for short useful lives more durable;
Making cells that were designed for indoor use temperature tolerant;
Making larger cells with stable mechanical, thermal, electrical and electrochemical behavior;
Making watt-hour sized cells suitable for use in kilowatt- and megawatt-hour arrays;
Developing battery management systems for kilowatt- and megawatt-hour arrays;
Increasing specific energy to a point where electric drive can be economically feasible;
Improving safety, vibration and impact resistance, and overall abuse tolerance;
Building new manufacturing infrastructure and materials supply chains;
Slashing costs by 75% or more in an industry where raw materials represent 65% of cell costs; and
Developing cost-effective recycling technologies and infrastructure for massive battery packs.

Over the last decade, lithium-ion Sony pcg-grs515m battery developers have made significant progress on a number of fronts, although cost reductions, specific energy gains and cost-effective recycling remain as elusive as unicorns. Some bright researcher may one day crack the code and solve all the technical challenges of lithium-ion batteries, but I'm not holding my breath.

For lead-acid battery developers, the principal technical challenges were far less daunting and included:

Making batteries that were designed for short useful lives more durable;
Making kilowatt-hour sized batteries suitable for use in megawatt-hour arrays;
Developing battery management systems for megawatt-hour arrays; and
Reducing charging times to permit more frequent and deeper cycling.

In a nutshell, the lead-acid sector had a simpler and shorter path. The industry had been making heavy-duty industrial batteries for decades. More importantly, researchers had a wider variety of technology and materials options because of the 30-year hiatus in lead-acid R&D. It was almost like the researchers returned from a 30-year vacation to find a different toolbox. As they started using advanced materials and manufacturing processes to improve the performance, cycle life and charging times of lead-acid compaq presario r3000 batteries, the results were astonishing.

Application requirements

The thorniest conceptual problem in energy storage is the variable value of a kilowatt-hour of stored electricity. The two primary determinants of value are time and place. Each of these characteristics, in turn, has a value hierarchy that ranges from very high to merely desirable.

In the simple case of a stationary application where the only variable is time, it's easy to create a value hierarchy. The three principal types of high value applications are:

Off-grid batteries that make renewable power available when the sun isn't shining or the wind isn't blowing;
Grid-connected batteries that insure system-wide grid integrity by smoothing minute-to-minute variation in user demand and power from variable resources; and
Commercial and industrial hp compaq business notebook nx6325 battery that provide uninterruptible power for mission critical operations.

While system reliability is the primary requirement for every high value application, total cost of ownership is a crucial secondary consideration and users are reluctant to pay a premium price for attributes they don't need. As you move down the food chain from critical reliability systems to desirable time-shifting applications, the economics get more complex and the users get more particular as they weigh the costs and benefits of energy storage against available alternatives. The complexities of the calculations are enormous, but the basic rules are clear.

Storage systems that cycle dozens of times per day are more valuable than systems that cycle once or twice;
Performance features that increase system cost without increasing end-user value are non-starters; and
The law of economic gravity is inviolate – the cheapest system that can do the work will win.

There are only a few cases where size and weight are mission critical for stationary systems. Examples include installations in existing buildings that have limited floor space or weight tolerances. As soon as you start evaluating shipping containers on a concrete pad, size and weight are irrelevant and the only features that matter are price and performance.

Portable power is usually more valuable than stationary power because it offers flexibility in both time and place. The most valuable batteries I own are in my cellphone and laptop where a few dozen watt-hours are priceless. Next in line is my starter Vostro 1400 Batteries. Once we move away from priceless applications, every energy storage decision involves trade-offs. The following simple examples highlight the economic issues that plague electric drive by assuming free electricity, a $5 gas price and an average fuel consumption of 400 gallons per year.

In a Prius-class HEV that cuts fuel use by 25%, a 1.3 kWh battery will save $500 a year or $385 per kWh;
In a Volt-class PHEV that cuts fuel use by 75%, a 16 kWh battery will save $1,500 a year or $94 per kWh;
In a short range Leaf-class EV that cuts fuel use by 100% but requires a second car for longer trips, a 24 kWh battery will save $2,000 a year or $83 per kWh;
In a short-range Tesla Model S that cuts fuel use by 100% but doesn't necessarily require a second car, a 45 kWh battery will save $2,000 a year or $44 per kWh; and
In a long-range Tesla Model S that cuts fuel use by 100% and won't require a second car, an 85 kWh battery will save $2,000 a year or $24 per kWh.

The examples deliberately ignore the question of battery cost because that fact is irrelevant to the fundamental truth that the economic value per kWh plummets as inspiron n5010 battery pack size increases. When it comes to portable power, small is beautiful but big is grossly inefficient.

Bill Reinert, Toyota's Advanced Technology group manager, recently described the problem as follows, "I used to be a big 100-miles-per-gallon guy. But I realized that we’re above the level of diminishing returns at 50 miles per gallon. So why not make a whole bunch of 50-miles-per-gallon cars and put people who are driving 20-miles-per-gallon cars into them?" It's a classic conflict where the technically possible is diametrically opposed to the economically sensible.

Lead-carbon batteries

The last decade has been an exciting time in the lead-acid battery industry as manufacturers respond to changing market dynamics. The first major technology transition was increased reliance on maintenance-free AGM batteries that are more robust and abuse tolerant than first-generation flooded batteries. The second major technology transition is the integration of varying amounts of carbon to reduce charging times and increase cycle-life. In a presentation at last September's Asian Battery Conference, the Advanced Lead Acid Battery Consortium offered an exhaustive technical analysis on the use of carbon in lead-acid hp compaq business notebook 6910p battery  and the approaches the principal manufacturers are taking.

The simplest, cheapest and most direct approach is adding fine carbon powders to the sponge lead pastes used in the negative electrodes of first- and second-generation lead-acid batteries. Extensive testing over the last decade has shown that changing the paste formulation to include up to 6% carbon by weight (±30% by volume) offers excellent cycleability and power while significantly reducing charging times. Johnson Controls (JCI), Exide Technologies (XIDE) and several other companies are already using carbon paste additives in enhanced versions of their flooded and AGM batteries with notable success. Others will follow. While carbon enhanced batteries have slightly lower specific energy than their predecessors, their 100 to 200 percent increase in cycle-life reduces the cost of energy storage by 30 to 50 percent.

A more complex approach is the Ultrabattery from CSIRO, Furukawa Battery and East Penn Manufacturing. It divides each negative electrode into two parts, a lead half and a carbon half. The end result is superior cyclability and power with even shorter charging times. The Ultrabattery is being tested in a variety of stationary and micro-hybrid applications and shows significant promise, including the potential to reduce the cost of energy storage by 50 to 70 percent.

The third and most sophisticated approach is the PbC battery from Axion Power International (AXPW.OB) that replaces the lead-based negative electrodes used in conventional Dell studio 1737 ac adapter batteries with a carbon electrode assembly. The resulting device is an "asymmetric lead-carbon capacitor" that offers the energy storage of a battery and the power and cycleability of a capacitor in a single hybrid device. The PbC has the lowest specific energy of all the emerging lead-carbon technologies, but it offers the cycleability and charge acceptance of the best lithium-ion batteries at a fraction of the cost. The PbC has been extensively tested for stationary, railroad, micro-hybrid and military applications and shows great promise, including the potential to slash the cost of energy storage by 80 percent or more.

The road forward

Lead-acid battery chemistry is one of the oldest, safest, most widely used and most environmentally benign technologies known to man. While lead-acid batteries can cause grave health problems if they're not manufactured, used and recycled in compliance with applicable regulations, the lead-acid battery industry has a stellar track record in the US and Europe where over 98% of used batteries are recycled to make new ones. According to USGS reports, over 95% of the lead used by US battery manufacturers in 2011 came from recycled batteries. No other closed-loop recycling ecosystem even comes close. When it comes to other types of batteries, similar closed-loop recycling ecosystems don't even exist.

The lead-acid battery sector has a massive global footprint with robust supply chains, distribution systems and recycling infrastructure. The new lead-carbon technologies have been developed to integrate seamlessly into the existing infrastructure and leverage the manufacturing base instead of displacing it. The commercial lead-carbon batteries that are rolling off the assembly lines today already offer 200 to 1,000 percent better performance than the Inspiron 1545 battery you think you know.

Lead-carbon batteries are heavy and bulky. They'll never be small or light enough for portable electronics or electric cars that need to travel long distances at highway speeds. As soon as you move away from these niche applications where size and weight are mission critical and money is no object, the advantages of lead-carbon batteries become overwhelming. Shakespeare said, "Nothing is so commonplace as to wish to be remarkable ." When it comes to energy storage, however, most of our needs are fairly mundane and there's no sense paying for extreme performance when adequate performance can do the necessary work for a fraction of the cost.

The first commercial products based on R&D conducted since the turn of the millennium are being launched today. The new products use cheap classic chemistry, but offer 21st century performance that many thought was the exclusive province of lithium-ion batteries. Over the next few years, these innovations will re-energize the lead acid battery sector with products that are vastly superior to their predecessors and competitors for applications where size and weight are not mission critical constraints.

Supercapacitors formed by the mighty power of DVD-RW drives - and a bit of graphite oxide and hard work...

What does graphite oxide, a DVD, and a burner with LightScribe functionality have in common? They're all part of a research project which resulted in the production of reliable ultrahigh energy density supercapactiors, a technology that's been touted as a possible solution to lacklustre energy storage in modern machines.
Producing these capacitors involves spreading a layer of graphite oxide onto an ordinary DVD, then inserting it into a LightScribe capable burner. The graphite is then reduced to a mechanically robust graphene lattice with high conductivity and surface area (an important factor for capacitance). Two of these sheets sandwiched together with a dielectric separating them act as a complete flexible capacitor, measuring less than 100 microns thick. The Science paper by Maher F. El-Kady, Veronica Strong, Sergey Dubin, and Richard B. Kaner describes the process in detail.
If there's one thing that's bottlenecking the rate of which performance increases on portable devices, it's the Canon fv40 Battery technology struggling to keep up. Power efficient System on Chip (SoC) designs, larger batteries, improved display technologies such as OLED, and tight coupling of circuitry such as 4G radios all help to curb the effects of Canon Eos 1100d Battery use. Even with all these efforts, the 'battery anxiety' issues of the current generation make it difficult to become truly portable. At some stage of the day you're going to find yourself tethered to a USB or wall outlet.
It's not just gadgets either, cars and even houses lack cheap reliable and high capacity battery solutions. The future of auto is electric, but we simply cannot afford to transfer Panasonic Lumix Dmc-fz3 Battery anxiety concerns to cars - that's just insanity, which is why most electric vehicles are hybrids, or just outright expensive to cater for larger energy capacity. If solar manages to become affordable enough for the average home owner, where will we store excess power?
Research into the area of Canon Eos-20d Battery tech is vital for current tech to improve into the future. Eventually stories of battery breakthroughs will come through with a solid marketable product, but until then, we can dream of a time where we can disappear for a week and still have a functional phone and laptop.

Transformer Prime as laptop replacement: Pros and cons

Summary: The Transformer Prime is the best Android tablet available today, and paired with the unique laptop dock can be used for many things formerly done on a laptop.
The unique laptop dock available for the Transformer Prime tablet makes it the best physical laptop replacement in the tablet world. It turns the Prime into a laptop, so that’s not surprising. I’ve been using it heavily for over a week for most things I use a laptop to do, and have some pros and cons for those considering this option
Laptop Battery life: I can’t say enough about having 18 - 20 hours on a charge with the Transformer Prime in the laptop dock. This is so liberating that I am never concerned about the kit lasting all day. It is wonderful.
Keyboard: ASUS has put a lot of work in making the keyboard work without compromise, and it shows the more I use it. I am a fast touch typist and I can really get going fast with the laptop dock. That’s important for a writer, and a great feature. The top row of special function keys plays a big role in my usage of the Transformer Prime and laptop dock, giving instant access to things like turning Bluetooth on/off, volume control, and screen brightness control. The Home key and Back key allow performing most Android functions without lifting my hands off the keys, a nice benefit. The four arrow keys on the keyboard make precise positioning of the cursor so much easier than using touch on the screen.
Trackpad: I didn’t think the trackpad would be something that would factor heavily in my usage, but ASUS has implemented it wonderfully. Whether it is using the trackpad to move the cursor around the Home screens or scrolling down web pages with two-finger trackpad control, the inclusion of a trackpad is a great feature of the laptop configuration.
SD slot: My camera is an older model with a full SD card for memory, and having a full slot on the laptop dock has come in handy. It is so efficient to pop the SD card in the dock and copy photos over to the tablet for additional work.
Portability: The ability to drop the Transformer Prime and laptop dock into very small bags makes it a no-brainer to take the combo just about everywhere I go. It weighs about two pounds, and is barely thicker together than just the tablet alone.
Cons:
Trackpad: Yes, one of the best features of the laptop dock can also drive me crazy at times. Accidentally touching the pad while typing can shoot the cursor all over the place, totally disrupting my workflow and forcing me to bring it back where it should be. This is not unique to the Transformer Prime dock, this is a problem on some laptops, too. Fortunately ASUS has provided a key to toggle the trackpad on and off, so as long as I remember to turn it off when typing all is OK.
Clumsy tablet removal: The tablet is easy to pop into the laptop dock, but that’s not the case for removing it. It’s a somewhat awkward two-hand process to flip the release lever and lift the tablet away from the dock. I like to use the Transformer Prime as a tablet most of the time, only using the dock when I want to do some serious writing. The combination is meant to be transported in laptop mode, so I find I have to frequently dock/undock it unnecessarily. It has gotten easier over time, but still not a fully natural process.
Conclusion:
The Transformer Prime is easily the best Android tablet I have used to date. It is extremely powerful and offers great utility for everything normally done with a tablet. Paired with the laptop dock that utility is extended far beyond that available from any tablet in the Android space. While expensive to purchase the tablet and dock strictly to replace a laptop, as there are cheap laptops for that purpose, it is a great alternative for tablet users who want to get additional functionality out of a slate.

Quill if you would rather handwrite notes.

Kingsoft Office for Word, Excel and PPT documents.

Various Email, Chat, Phone, and Video Conference Apps.

Chrome Web Browser.

Many Remote Desktop Apps.

There are plenty of options to work from the tablet and while not as full featured as a desktop software package, it is still very well done!

How do I get multiple windows next to each other, so that I can read my notes, whilst writing a document?

Next to a decent keyboard, being able to see multiple windows next to each other is the most important thing for me, when working.
camcost@... 1 day ago
With the keyboard attached, you are no longer in the tablet frame of mind. You have both physically and mentally made the switch to laptop.

It's very much like the PC tablets which have been on the market for a decade. Though the tablet/touch function was a big selling point, anytime one was using the thing as a laptop, you tended to forget you were using a touch device.

We must remember to never think of a keyboard as a huge leap forward. If anything, it's a step backwards, and is only a temporary solution until a better solution is developed. A computer's keyboard is simply a variation of a typewriter which goes back 150 years! It's good for what it does, but is it really the best alternative we have? I say to use some vision.

@ Peter Perry: It does come with the keyboard, at least in The UK. You cold buy the Transformer without it but the Prime you cannot.

Not to get too side-tracked, but I feel that for now on Android, Dolphin is the superior browser. I've tried FF, Chrome and built-in Android browser, and Dolphin just has so much more going for it: speed, preferences, gestures. Of course Chrome for Android is in beta, and will only get better.
jonandkelly 1 day ago
on my asus. After the ICS update I actually find the stock browser to be the best. Looking forward to more improvements with Chrome but for right now it's still a bit too stuttery for me. the Stock browser is very smooth. Dolphin I haven't given it alot of attention as of late, but your post gives me something to look forward to in playing around and testing.

Fletchguy, where you are you looking? Best Buy's website indicates the 32GB model is not available online, and a check of stores reveals "unavailable." Fry's lists the Transformer, but not the Transformer Prime. I agree with ICU. Most sites don't have them listed at all or unavailable. It's been that way for weeks.

Hi!
Can you extend this article, by reviewing what a standard Windows SysAdmin can, and can't, do with this lap-tablet-top?
For example, Peter Perry already mentioned some key apps, but if you could show some more detailed examples, it would be very nice!
I'm so used working with different apps on side-by-side windows, and i believe it will not be possible for me to work that way... i don't even know if there's a way to do something that works like an Alt+Tab on android...

camcost@... 1 day ago
I believe by the examples you give, this is probably not the item you would be interested in. When it's all said and done, this is still a Android tablet with an attached keyboard, period. The keyboard makes it easier when typing long heavily-worded documents, but besides that advantage, it's not meant to be a replacement for a true laptop or desktop.

The Trans Prime has a very good file/folder system too so it's very laptop like in that sense too. You can easily create Office compatible docs. And it does things laptops don't do. Like voice recognition which is built-in to Android. How about the 18 hours of Dell Latitude E4310 battery. No netbook, let alone laptop can last that long. How about the numerous FREE apps available for Android on the Market, Amazon, and Nividia sites? And, lastly, of course, is the aspect of the touch screen. I find that the combo of touch screen and keyboard access at the same time is great and I'm using it more and more. Again, another thing you can't do with a regular laptop.
Sorry mrxxxman

I've seen netbooks with over 20 hours of HP Probook 4510S Battery life (which really isn't that shocking, seeing as they don't have to conform to slate-like size restrictions).
@Aerowind
mrxxxman 1 day ago
What Netbook is rated over 20 hours while in use that's of comparable size. And don't forget the 1280x800 resolution of the Prime screen too. It only makes sense to compare it to the same size device.
re: More pros and cons, please!
matthewstoops 1 day ago
Alt+Tab works fine, it's just that the Alt key is to the RIGHT of the space bar. The "search" key is to the left, and I keep hitting it by mistake when I want to change apps.

As far as I'm aware, there is no way to have multiple windows for apps next to each other. Only one app owns the screen at a time. While the Prime can act as a laptop in some respects, this is one place where Android cannot keep up with a more functional OS like Linux/OS X/Windoz. But it's not meant too either.
A Windows SysAdmin should write it, I guess
danbi 1 day ago
You can't expect from a journalist to write from point of view of Windows SysAdmin. Let's hope someone will show up.

I have managed without issues UNIX systems with a iPad. I can imagine that it will not be much different with Android. Without having special-purpose application, that is -- just an terminal emulator. No trouble to switch back and forth between the applications -- it all depends on your habits an dyes, there are tasks that require huge cuts and pastes etc that are more difficult on a tablet -- with keyboard or not. For such tasks, you need an special purpose application.
I love my Transformer
MadWhiteHatter 1 day ago
All I can say is that I love mine. The skinning was good. The keyboard kicks ass mainly to provide the tablet protection. The Acer aspire 4738z battery life is great, so much so that I can use the keyboard to provide extra power to my cell phone if I need to. What TiagoViana mentions is probably my biggest issue with Android, not necessarily the Transformer. I'd love to have two windows open next to each other. That said, it isn't a complete PC replacement. It is why I have a Windows tablet PC convertible as well, the HP 2730p.
I'd love one

I have been watching this machine grow. Not having the money to jump onto the yearly Apple Upgrade cycle and not wanting a 4th device (ie desk, lap, pad, phone) this is the best so far.

But, I'd still like to know if it can function (as my laptop does) as a full fledged desktop with 28" monitor, full scale Kb and of course the old fashioned mouse, supplemented minimally with usb2 to high capacity disks?

It won't be long and we'll be there...
Sorry, there's one thing that's stopping me still.
kcredden2 1 day ago
I just buried a T22 which I used for 13 years. I seriously doubt a Tablet with /hard wired batteries/ would last 13 years. The laptop batteries would probably last about 2 - 3. Then how do you replace them? Oh I forgot, you spend $500 for a another tablet.

Also $500 for a tablet, with a dock? Sorry, the Asus Eees do the same thing, weight around the same weight, HP Compaq 6910p battery are replaceable, as well as the HD (and you get far more HD space.)

Nope for my money a notebook/netbook is still the way to go.
I am excited about this concept
tgschmidt 1 day ago
Having one device that you can use for multiple functions. I really like this. Buying one "brain" item that can dock or be linked to perform several functions.

My Droid4 phone does this. I have the Lapdock 500 Pro and have been using it for the vast majority of my computing needs for almost 6 weeks now. I also have the HD dock for it and stream Netflix movies and view photos on my big screen & play music through my surround sound system.

The Lapdock 500 has 2 USB ports and an SD card reader. HP Compaq 6710b battery  life is not as good as the ASUS combo, but I can get about 8 hours if my phone is fully charged when I dock it.

I think we are about 2 years away from having a legitimate one device does it all solution that most people will be satisfied with. I am really looking forward to that.
Multiple Windows
chart8006 1 day ago
There is a new android browser out that will float over the other windows called Onskreen, they also have a calculator that does the same. It's not as fully featured as Dolhin but it allows you to look up stuff while keeping another app open to type or draw in, and to do some calculating.
An Interesting point, however...
bigjim01@... 1 day ago
I think that this is an interesting point, and I am currently using an iPad to replace a notebook computer for my personal computing needs. The only thing that I have not been able to perform on my iPad is the ability to write programs (not web pages) and have them run on the device. This has only been at most 10% of my portable computing needs. The other concern that I would have with this device is the ability to remove Android from device and install a mobile version of Linux. I do not trust Google and I would not want to plug any information into any Google service. I do not trust that Google has not installed back doors into the system so that they can suck all my information from the device, and then sell that information to advertisers.
You don't trust Google but...
Johan Safari 1 day ago
You trust Apple? Just Google (pun intended) and see how Apple and others collected your info.
And yes, you can run Linux on the Prime either native or together. Again, trust Google to give you the answer. wink

I don't believe that there will ever be a device that everyone will be satisfied with. I first learned about the Transformer about the middle of last year and followed it religiously until I was able to place an order in November for delivery around Christmas. I finally go the tablet part at the end of January and the keyboard in early February. I am overwhelmed with the structure and capability of the Prime and hope to have it converted to doing all of the things that I do on it. I have always been a fan of MS Outlook and don't have a single app that will do all of the things that Outlook will do and would appreciate suggestions from others who are faced with the same problem. In all of the replies above, no one has mentioned the wonderful screen resolution or the 8 Meg Camera that does portrait like pictures. The original story also says that he has difficulty separating the tablet from the keyboard but I assure you that it is easier to do than shutting my Windows laptop down and closing the computer. You can do the process with the Transormer turned on or off and it will convert to the new system immediately.
The biggest negative I can think of is the fingerprints on the screen but I can live with that.
What about printers, hard drives, DVD players/burners?
nfordzdn 1 day ago
How can you claim the AT can replace notebooks and not address these issues?

Can the average notebook owner swap in a Transformer without needing a techie to get these other things going?

Also, what makes a Transformer superior to, say, a Toshiba Thrive which has a full-size USB (plug in an external hard drive and flash cards), mini-USB, full-size HDMI (plug in an external monitor with a standard HDMI cable), full-size SD slot, swappable ACER Aspire 5732z Battery, etc., plus the ability to hook up your choice of Bluetooth
Flawed assessment
lgpOnTheMove 1 day ago
No mention of price comparison to notebooks. No mention of the standard features that come with a budget notebook that this solution is missing. No mention of how a slate+keyboard solution compares with a netbook. No mention of the app limitations or how to get around them...

Why not talk about productivity and multimedia performance? Why not look at alternatives that cost less and offer more bang for the buck? Are we only pretending to be impartial?

I would expect a far critical observer to point out more cons than what you have James. This solution really is no more than a glorified word processor for people that have very limited needs and little creativity. Happy typing to you!

I was rethinking things and while for what I do I don't agree that I would necessarly try to replace a laptop with an android or ipad, I am rethinking the laptop itself.

I realize what I hate is small laptop keyboards and trackpads for full productivity. If I want to do serious development work (as I do), I want to sit at a desk with a full size keyboard and mouse and not on the couch or something. You can do this with a laptop, but then you have the extraneous laptop on the desk.

For this reason, I am considering going back to a full size under desk machine, only, for productivity and then a transformer prime for optional light casual typing of email and stuff on the couch where your lap won't get hot and tired from the weight and of course normal tablet on the go uses (I use mine absoutely everywhere, thanks in part to velcro). I never seem to get any real work done on the couch with a laptop anyway.
