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.
