Apple laptop battery with attention, here's how to use a greater extent a good laptop. Just a little note, you can maximize the use of Apple laptop battery (that must be charged before use) and battery life. One of the most important point is that, in the appropriate temperature range to use your Apple notebook computer,. Do not be locked in the summer heat on the closed areas.
Apple laptop notebook computer running temperature optimum temperature at 50 ° to 95 ° range. You should be stored in a -13 ° to 113 ° environment. That is, 10 ° to 35 ° and -25 ° to 45 ° is to run the laptop with the appropriate storage temperature. Try to make your Apple computer close to room temperature (22 ° C) is ideal.
New laptop when you first bought the laptop using the new computer, remember to full power, and then run Software Update to make sure your computer is equipped with the latest software. Apple regularly releases software updates to improve Acer aspire 5738z battery performance.
Maintenance standards for the maintenance of a lithium Dell latitude d630 battery is very important, is to make the battery in the electronic state at all times maintain liquidity. Apple recommends that you do not have to use laptop power supply. Ideal way to use, going to use your Apple notebook computer batteries, Back at the office using the power for charging. This battery can keep the flow of the liquid state. On the other hand, if you use the desktop computer in the company, but only occasionally use your laptop on the go, Apple recommends you charge the Acer Aspire 5742 battery at least monthly, and discharge time.
How long-term storage
If your laptop computer will be idle for more than six months or more, Apple's official suggest that you remove the battery, and maintained at 50% charge state. If the store when the power is zero, the battery will result due to excessive discharge can not afford any charge. Conversely, if the store when the battery is fully charged, will be some loss of battery capacity, which reduces the SAMSUNG PL60 Charger battery usage time. Please remove the batteries after storage at the appropriate temperature.
You can choose the best settings Apple laptop computers use to maximize battery life.
1, energy: Energy Saver control panel offers several settings options for you to control Apple notebook power consumption. As long as a boot, the computer will run to set up. Set in the control of state power, the computer itself will dim the screen brightness, and moderate use of other features. If you change the setting to maximize performance, power will be depleted faster.
2, brightness: the screen will be transferred to the most comfortable low brightness can maximize Sony NP-BN1 Charger battery life. For example, when you watch a DVD on the plane, if all the lights off around you do not need the strongest screen brightness.

How to properly charge the battery for notebook
Bought a new lithium-ion laptop batteries used in the first, to conduct three complete charge and discharge, the battery fully charged at least once a power, then power exhausted, repeated three times before use. To activate the chemicals inside the battery, the electrochemical reaction within the battery into the best state, in the future can be freely used in the charge that is useful, but within a month to ensure that there must be a complete battery discharge, so depth of discharge can stimulate the activation of cell performance, battery life plays a key role. If more than 3 months the battery is not used again until the same should also be carried out with the new battery charge and discharge completely 3 times to make sure to activate the battery.
The use of nickel-metal hydride Dell xps m1330 battery, which must control the charge time should be careful not to frequent over-charging, otherwise it will shorten battery life. In addition, Ni-MH battery should be fully discharged before charging, the charge should also be fully charged, and in normal use before, but also required to complete three complete charge and discharge.
Most users accustomed to using a laptop computer each time, plug the AC power supply, very little battery-powered laptop. In fact, should be at least a month to supply one or two batteries, the battery completely run out, connect the AC full-time. Remember this one, for rechargeable batteries, the battery will run out and then filled with useful and harmless, because the use of lithium-ion hp laptop battery there is a certain inertia effects, for a long time not to use lithium-ion loss of activity, the need reactivated. When the notebook computer using AC in the room when it is best to remove the battery, so it is often a state of charge. Best off when charging laptop, the battery is fully charged, do not unplug the power drop in the charge. Charging is completed, it should be within 30 minutes after use.
In addition, because the vostro 1400 battery is easy to run out of power, but only a majority of laptop batteries, therefore, part of the pen to the computer manufacturers to develop a fast charge feature that lets users run out of power after power with the fastest speed to add . For example, Dell laptops have ExpressCharge feature, you can recharge in one hour more than 90%. Why not 100%? Because, according to Li-ion battery charge and discharge characteristics, if the regular fast charging to 100%, the battery life on the big report shorter, so the back of 10% will be replaced by the slow-fast-charge before the charge to extend battery life.
Without this function for a standard laptop, the best way is to charge off, charge off shorter than start charging more than 30% charge time.
Third, the laptop battery tips
How to make good use of dell laptop battery battery, how to extend their use of time and the life of the other issues, no doubt troubled by the majority of laptop users in the heart of a problem.
(A) to sleep fast
Temporarily using a laptop computer, to save battery power, we can set the power management options, allowing the system to sleep after a period of time, but shorter or longer will have to wait a few minutes, there is no way to make the notebook computer system immediately enter the sleep state?
The notebook computer system to sleep, a quick and easy way is to directly turn off the display. Press display just little things, you can immediately make the laptop sleep, effectively conserve battery power. When you need to re-use, simply open the display, the system will automatically return to the state before the operation.
(B) screen-saving mode
TFT screen is the largest notebook computer power components, in order to reduce the use of the battery when the power it consumes, notebook computer manufacturers of all kinds of devices, but in general are based on the lower screen brightness, and even off-screen method.
In some laptops the power management settings you can customize the brightness of the screen, most laptops can be specific shortcut keys adjust the screen brightness, generally 6 to 8 level brightness adjustment.
(C) energy-saving settings
Desktop using the AC, the computer most people may not attach great importance to energy-saving features, but need to use Universal External battery-powered notebook computers, the use of energy-saving features should be taken seriously. How to design more energy-efficient computer hardware, this is not the user to solve the problem. The user can do is set the computer on the effective use of energy-saving options.
Energy-saving setting, there are two require the user to adjust: First, the computer's BIOS setup program on the energy saving mode setting; the most important is in the operating system has many energy-saving settings and operation. In the practical implementation of computer systems, Windows systems should give priority to energy-saving settings in the CMOS settings.
1. BIOS settings in the Energy
In the CMOS settings and large have a "Power Savings", which you can select "Maximum Battery Life" and "Maximum Performance" and other options. "Maximum latitude d630 battery Life" is the default power saving mode setting. Laptop power saving mode in several states, such as Idle Mode Idle Mode, Standby Mode standby (wait) mode, Suspend Mode suspension (sleep) mode. These settings on the laptop, able to regulate power consumption, mainly in the computer power state, the timely closure of some facilities without the use of the system. If the wait state, turn off the monitor and hard drive; to sleep, in addition to turning off the display and hard drive, but also the contents of memory can be saved to the hard disk, the basic maintenance of the entire computer system off, once activated, or restart the computer, the desktop return to the exact state before sleep. Energy-saving settings in the CMOS is mainly set by the Idle Mode Standby Mode to enter the Standby Timeout time set by the Standby Mode Suspend Mode to enter the Suspend Timeout time. Phoenix BIOS laptops use the majority. Different BIOS settings may be somewhat different energy, should carefully read the screen prompts.
2. Windows in energy-saving settings
For general users, in the Windows system may operate better understanding of energy management simpler. Windows help file, in the "management of hardware and software" entries, there are two energy-saving notebook computers with the content: "Managing energy consumption" and "use of portable machine" in the "management of portable computer power." Energy-saving settings during Windows, should read these.
In the Windows "Control Panel", click "Power Management", you can open the "Power Management Properties" dialog box. In the "Power Management Properties" dialog box, should be "power scheme" set to "Portable / Laptop" and reasonable arrangements "system waiting for", "Close the Monitor," "Turn off hard disks" option . The computer can manipulate the different options will have some differences, the new factory and the latest computer software will be more operational options, a detailed set of functions should be based on the computer itself and the Windows help file to.
In addition, if your laptop built-in infrared port, when not to ban it, you can extend acer laptop battery life.
(D) alarm settings
Set the battery alarm in time to give prompt the user to save the information. Method is to click open the "Control Panel", double-click "Power" option, click on "alert" menu bar, "Low battery alarm" column for the Windows 98 default 10%, "a serious shortage of battery alarm" column for the Windows 98 default 3% can make the appropriate changes as needed. Click on both the [Alarm Response] button, the "Sound Alarm" and "message" is selected, the "power level" is optional. This is used when the battery alarm limit, a warning window will pop up, and the buzzer alarm will sound to prompt the user to save information in a timely manner. Finally click [OK] button to exit the power management settings.
(E) on energy-saving function
In the "extended HP f2299a laptop battery life technology" section, we have introduced energy-saving feature is a CPU usage of the technology, which allows the performance of laptop computers will play its battery to achieve the best balance between.
Most new models of notebook computers in the BIOS, the CPU energy-saving technologies are given support is enabled by default, if not open as long as the BIOS will support the option to open it OK.
(F) the use of third-party software to monitor battery status
In addition to Windows built-in power management features, there are a lot of utility to monitor battery status. For example, PowerCenter is a power monitoring tool, available for free download (http://me MBers.xoom.com / TimothyBug / powercenter / index.htm). Only 800KB, is a service designed for notebook software. PowerCenter not only shows the percentage of battery capacity, but also to show the actual hours and minutes the time available.
There are three kinds of PowerCenter display.
(1) FullDisplay: In the open window displays detailed information, including the use of battery or AC power, the percentage of battery remaining and available time.
(2) CompactDisplay: in use is always displayed at the top of the window.
(3) MinimizeDisplay: PowerCenter reduced to make the Windows taskbar, and the information is relatively simple.
PowerCenter is also attached to a control center, can make up to six kinds of warning. When the battery - down to a certain extent, timely warning to the user, save the file being processed. In order not to waste electricity and CPU resources, PowerCenter automatically detect the battery status changes.
(G) intentionally run out of battery
Regularly run out of battery, in order to ensure a full charge. If you need to completely run out of battery power, which would be: In the Power Management dialog box, select the Battery Drain this particular power mode, all of its three Running on Batteries options are set to Never, this laptop is the computer on will continue to run. Select the mode, then enter the Alarms tab, cancel the Low Battery and Critical Battery Warning check box check mark (so that when Dell inspiron 1410 ac adapter battery power is low, the machine will not enter the suspended state). Next, let the computer run the CPU-time tasks, such as the computer automatically run some of the computational complexity of the 3D demo program, which will soon run out of battery power remaining, of course, these disposal Do not forget to unplug the AC the plug.
(H) How to calibrate battery
To enable the battery to achieve the best performance, certain models of notebook computer provides a battery calibration feature, the first time using the battery, this feature can be used to calibrate the battery. Power calibration procedure will be exhausted, and then re-charged, which would enable the correct Windows battery meter to monitor inspiron 1545 battery status. Calibrate the battery as follows.
(1) into the power adapter.
(2) Restart the computer, start screen appears, press F2 to enter BIOS setup.
(3) in the BIOS, select the Exit item, and select BatteryAuto-Learning option.
(4) Press Enter, select BatteryAuto-Learning option (it will appear in front of a "√").
(5) Select the Exit project SaveandExit option to save your settings and exit the BIOS Setup.
(6) The system will reboot and start battery calibration.
(I) how to test battery-powered time
Mastered how to make the longer the battery can supply, many laptop users are also very much like to master the battery performance and understanding of their batteries in the end how much time to work, so as not to appear when the batteries need to use it, "strike" situation. But how can a proper understanding of their own battery time? We can use BatteryMark4.0.1 software to test the dell xps m1710 charger battery life.
, Methods of laptop battery repair
(A) cause damage to the battery
Laptop battery a long time, I am often dissatisfied with battery charge, and even show the battery is damaged, specific performance is larger resistance in the charging voltage rises faster at both ends. So easy to determine the charge control circuit has been filled, the capacity falls. Since relatively large battery internal resistance, discharge voltage drop, high speed, so the system is not easily mistaken for voltage, low battery. In that relatively short battery life, should take appropriate measures.
(B) the battery refresh program to restore the battery discharge time
Big brand laptop has a battery refresh program, we can use it to repair the battery. For example: a IBMThinkpad390/262650 based laptop, the Sony vaio vgn-cr140e battery with a nickel-metal hydride (Ni-Mh) batteries, as usual charge and discharge properly, causing the battery discharge time is short, only less than 5 minutes, if carrying a laptop to work, then it is very inconvenient, what can restore the battery discharge time?
For the above, we can use the IBM has launched a battery refresh program to refresh the battery to discharge recovery time, specifically as follows.
(1) the use of AC power to the notebook computer, the first to ftp://fip. pc. ibm. com / pub / pccbbs / mobiles / isbr01ww. exe to download IBM provides TP390/390e/390x series laptop battery for Dell XPS M1330 refresh program.
(2) Restart your computer, press F8 to enter boot menu, and select safe DOS mode.
(3) into the directory where the file you just downloaded, perform a battery refresh program isbr0lww, exe, reading the warning message, insert the floppy disk as required, and then press the Enter key to execute the self-extracting operations.
(4) Boot the computer with this floppy disk, the screen StartingPC-DOS. . . Prompt information.
(5) Follow the prompts to unplug the AC power, the program will automatically Ni-Mh battery discharge, the discharge is completed, the system will automatically shut down.
(6) The battery temperature is high at this time, should not immediately start, let the battery cool for a while, plug the AC power.
(7) Boot the computer with a floppy disk, the Autoexec. bat file will run automatically refresh program, and asks the user whether to proceed. Select yes and press Enter.
(8) At this point, the program began to refresh the battery for Lenovo IdeaPad Y550A refresh, the process soon, when the returns to the DOS prompt A:> when that refresh is complete.
(9) Turn off the computer and charge the battery until the light turns green so far.
(10) The above procedure was repeated three times to get the best results.
In addition, many lithium battery pack failure is the result of a failure of energy-saving core, this phenomenon can not be avoided. Because each cell batteries can not be exactly the same nature, with some slightly lower quality long after the beginning of aging, and destroyed the whole (the series after) the discharge curve. Interest and ability of the reader can try to open the battery pack, with the help of the multimeter, you can quickly find the damaged batteries (abnormal voltage). If conditions permit, according to the corresponding parameters of replacement Lenovo 92P1213 AC Adapter batteries can be qualified product.
The use of nickel-metal hydride Dell xps m1330 battery, which must control the charge time should be careful not to frequent over-charging, otherwise it will shorten battery life. In addition, Ni-MH battery should be fully discharged before charging, the charge should also be fully charged, and in normal use before, but also required to complete three complete charge and discharge.

Depth analysis of laptop battery
Notebook how long the first charge is appropriate, the explanation must be in business more than 10 hours to ensure the laptop battery is fully activated. Although we are very careful to use our laptop batteries, but the books of the standby time is less and less. So how laptop battery charging is the most appropriate?
I give you a brief introduction:
Depth analysis of laptop battery materials
Lithium-ion battery cathode materials are usually composed of active compounds of lithium, the negative is a special molecular structure of carbon. Common cathode materials mainly composed of LiCoO2, charging, added to the Canon Bp-511 Battery positive pole of the electric potential of compounds to force release of lithium ions, embedded negative elements arranged in lamellar structure of carbon. Discharge, the lithium ion from the lamellar structure of the carbon in precipitation, re-cathode combination of compounds. Lithium-ion movement generates a current.
Although the principle is very simple chemical reaction, but in the actual industrial production, the practical problems need to be considered much more: the cathode material additives needed to maintain the activity of multiple charge-discharge, cathode materials needed to design the molecular structure level accommodate more lithium ions; fill in the electrolyte between the positive and negative, in addition to stability, but also has good electrical conductivity, reducing the HP Compaq Mobile Workstation nw9440 Laptop AC Adapter battery's internal resistance.
Although lithium-ion battery with little memory effect of nickel-cadmium batteries, memory effect is the principle of crystallization in lithium battery is almost no reaction. However, lithium-ion battery capacity after repeated charge-discharge will continue to decline, its causes are complex and varied. Mainly positive and negative changes in the material itself, from the molecular level, the positive and negative ion on the hole to accommodate the structure will gradually collapse, clogging; from the chemical point of view, is the active anode material is passive, there's another side to form a stable compounds. Physical cathode material will appear on the gradual falling off, etc., in short, ultimately reducing the Compaq 354126-001 Battery will be free to move in the charge-discharge process of lithium-ion number.
Overcharge and over discharge, lithium-ion battery anode cause permanent damage, from the molecular level, intuitive understanding, excessive discharge of carbon anode will lead to excessive release of lithium ion and makes its lamellar structure collapse, excessive Rechargeable lithium-ion will too hard to go into the negative carbon structure, while making some of the lithium-ion no longer be released.

So we need to calibrate the Samsung es70 Battery charge-discharge deep chips.
I give you a brief introduction:
Depth analysis of laptop battery materials
Lithium-ion battery cathode materials are usually composed of active compounds of lithium, the negative is a special molecular structure of carbon. Common cathode materials mainly composed of LiCoO2, charging, added to the Canon Bp-511 Battery positive pole of the electric potential of compounds to force release of lithium ions, embedded negative elements arranged in lamellar structure of carbon. Discharge, the lithium ion from the lamellar structure of the carbon in precipitation, re-cathode combination of compounds. Lithium-ion movement generates a current.
Although the principle is very simple chemical reaction, but in the actual industrial production, the practical problems need to be considered much more: the cathode material additives needed to maintain the activity of multiple charge-discharge, cathode materials needed to design the molecular structure level accommodate more lithium ions; fill in the electrolyte between the positive and negative, in addition to stability, but also has good electrical conductivity, reducing the HP Compaq Mobile Workstation nw9440 Laptop AC Adapter battery's internal resistance.
Although lithium-ion battery with little memory effect of nickel-cadmium batteries, memory effect is the principle of crystallization in lithium battery is almost no reaction. However, lithium-ion battery capacity after repeated charge-discharge will continue to decline, its causes are complex and varied. Mainly positive and negative changes in the material itself, from the molecular level, the positive and negative ion on the hole to accommodate the structure will gradually collapse, clogging; from the chemical point of view, is the active anode material is passive, there's another side to form a stable compounds. Physical cathode material will appear on the gradual falling off, etc., in short, ultimately reducing the Compaq 354126-001 Battery will be free to move in the charge-discharge process of lithium-ion number.
Overcharge and over discharge, lithium-ion battery anode cause permanent damage, from the molecular level, intuitive understanding, excessive discharge of carbon anode will lead to excessive release of lithium ion and makes its lamellar structure collapse, excessive Rechargeable lithium-ion will too hard to go into the negative carbon structure, while making some of the lithium-ion no longer be released. This is the lithium-ion HP Pavilion dv6-1100 Laptop AC Adapter batteries are usually equipped with charge and discharge control circuit causes.
Not suitable for the temperature, the internal lithium-ion battery will lead to other chemical reaction of the compounds we do not want to see, so many of the lithium ion battery between the positive and negative temperature with protective membrane or electrolyte additives.

Lithium battery charging principles
1 rechargeable lithium-ion laptop battery suitable for the requirements of the most current?
Requirements for lithium-ion battery (GB/T18287 2000 specification): First of constant current charging, the current is constant, while the battery voltage is gradually increased as the charging process, when the HP Compaq Business Notebook NX6310 Battery terminal voltage reaches 4.2V (4.1V), change the constant current charging for the constant voltage charging, the voltage must be current batteries according to the degree of saturation, with the charging process to gradually reduce, when reduced to 0.01C, that the charge termination. (C is the control current of the battery nominal capacity of a representation, such as the Panasonic Lumix Dmc-lc5 Battery capacity is 1000mAh, 1C charge current is 1000mA, note mA is not Ah, 0.01C is 10mA.) Why do you think the end of 0.01C for the charge: This is required by national standards GB/T18287-2000 also discuss the resulting. Used to be common to 20mA to end, the Ministry of Posts and Telecommunications industry standard YD/T998-1999 is such a requirement, that no matter how much battery capacity, stop current is 20mA. National standard will help charge of 0.01C fuller advantage through the identification of a party manufacturers. In addition, the national standard of no more than 8 hours charging time, that even if not yet reached 0.01C, 8 hours to, and also that the end of charge. (No problem, the quality of the battery, should be within 8 hours to reach 0.01C, poor quality of the Panasonic Nv-gs11 Battery, wait and meaningless) lithium-ion or lithium polymer rechargeable battery pack for the best rate of 1C, which means that a 1000 mAh battery pack is necessary to 1000mA of current for fast charging, charge rate can be achieved in this shortest charging time, without sacrificing the performance and shorten battery life. For increasing battery capacity, charge want to achieve this satisfaction rate, increase charge current value is inevitable.
(2) the requirements of lithium-ion Acer Aspire 3610 Battery charging voltage is the most appropriate number?
Lithium-ion battery nominal voltage 3.7V (3.6V), charging cut-off voltage 4.2V (4.1V, according to brand batteries have different designs) is how the difference between the battery 4.1V or 4.2V: consumers are indistinguishable, This depends on batteries manufacturer of the product specifications. Some brands of batteries is 4.1V and 4.2V common, such as A & TB (Toshiba), the domestic manufacturers is basically 4.2V. The 4.1V to 4.2V rechargeable batteries what will happen: Apple a1281 Battery capacity will increase, feeling useful, standby time increases, but will shorten battery life. Such as the original 500, reduced to 300. Similarly, the 4.2V batteries overcharge, will lower its short life. Lithium-ion batteries is very delicate. Since the battery inside a protective plate, we can rest assured it: No, because the protection board cut-off parameter is 4.35V (this is good, the bad to 4.4 to 4.5V), the protection board is to meet the case, and if each times have been charged, the Apple a1280 Battery will soon decay.

HP laptop batteries repair methods
Here are some commonly used HP laptop battery fix for one year is not aging batteries HP laptop batteries original batteries and compatible batteries are suitable for reference:
HP notebook battery repair case scenario:
Scene 1: HP laptop batteries do not long home, such as the battery drawer a few months, the battery life on the corresponding shorter, not serious on the charge into the electricity;
Scene 2: because of its aging batteries, choose the repair shop directly on the outside for batteries, this battery will need to do some self-recovery.
Scene 3: Because the battery for COMPAQ Presario R4000 for more than three months, but within a year, but only the use of time in 10 months, the battery standby time is shorter than the previous lot.
These scenarios are often encountered in life.
How to repair HP laptop battery:
hp laptop battery repair for Scene 1, refer to the following steps
First boot, press the "F2" to enter the BIOS menu; into the Power menu.
Step into the Power menu, find the "Start Battery Calibration" option, "Battery Calibration", or "proof battery," select it, enter execution.
Step into a blue screen and prompts in English, the laptop power adapter plugged in charging. So the battery is full, the screen prompts disconnect the power adapter. Continued after the laptop on latitude e5500 ac adapter discharge until the battery runs out.
Automatically shut down after the battery runs out, connect the power adapter to charge, but does not boot. Fully charged (charging indicator light goes out), the laptop battery calibration process is complete.
This behavior takes about 4-5 hours! Need books BIOS with this function.
hp laptop battery repair for Scene 2, refer to the following steps
If the laptop BIOS can not find the laptop battery calibration option.
The first step into the "Power Options." Select "power scheme" to "always open", set "Turn off monitor", "Turn off hard disks" for the shortest possible time, set "System standby" to "never"
The second step to cancel the "Power Options" and "warning" alert options for all
The third step is set up, close all applications, shut down WIFI, unplug the power adapter, battery-powered. Without any extra operations, until the battery for Dell XPS M1530 runs automatically after shutdown
This behavior is to be made an appointment a few hours. Discharged, with power adapter, the battery is full, complete a HP laptop battery calibration.
hp laptop battery repair for Scene 3, refer to the following steps
Download a software, called "BatteryMon", many versions of this material is designed for a small laptop battery monitoring software, you can display the discharge curve, and the installation will run automatically.
The first step to open: My Computer -> Control Panel -> Power Options -> Power schemes to use the battery all the time parameters selected as the "never"
The second step will be "alert" that the project to remove the hook
In doing the above settings, in accordance with the principle of full discharged battery charge and discharge, continuous discharge back and forth three times.
Remarks:
As a long time using a laptop with the AC, two days ago suddenly found to be charging a sony vaio pcg-fxa49 dc adapter battery check display 0, can not discharge the battery that is bad, check that the Internet is the need for a battery, cheap batteries also need 200 , so he had some way they want to repair, the results quite satisfactory, can not boot from the battery after the repair can now use more than 1 hour, following the repair method put me to share with everyone.
First check whether the battery is really damaged. Unplug the AC power, then press the laptop power button, see the battery light is flashing, if the flash, laptop battery under normal circumstances should be no problem. With a multimeter Measure the battery voltage, if the voltage is 11 volts, the dell xps m1530 battery charge and discharge due to the long wrong can not be discharged.
And is fully discharged. Remove the battery from the notebook, and then find a large resistor (you can also use routers, hubs, switches and the like), a full discharge, because I did not find major resistance, so to find a useless router discharge, the results were quite good, the router lights to show whether the above discharge fully, with the wires connecting the battery and the router, the router if the connection is correct light will light up, if you do not look down the right line on it. Even after completing the discharge is to wait for completion of voltage with a multimeter is best to look at the amount of a few tenths. Then install the HP Compaq Business Notebook 8510p battery to the laptop, for 8 hours of charging, red end power, unplug the AC power, so laptop own discharge, until the automatic shut down and then it just means full discharge, so that more than 3 consecutive full discharge your battery is basically back to the performance of the factory.
These are my own repair cells that experience, I hope useful.
