how to distinguish battery is 4.1V or 4.2V

how to distinguish battery is 4.1V or 4.2V: consumers do not distinguish between

, depending on the products of batteries manufacturers specifications. Some brands of batteries are 4.1V and 4.2V common, such as A & TB (Toshiba), the domestic manufacturers is basically a 4.2V, but there are exceptions, such as Tianjin power of God 4.1V (but also by a 4.2V).

5, the rechargeable batteries 4.1V to 4.2V happen: will increase battery capacity, feels good to use, standby time increases, but will shorten battery life. Such as the original 500, reduced to 300. Similarly, the 4.2V rechargeable batteries have also shortened life expectancy. Lithium-ion batteries is very delicate.

6, since the battery inside a protective plate, we can rest assured it: No, because the cut-off parameter is the protection board 4.35V (this is good, the bad to 4.4 to 4.5V), protection board is to meet in case, and If each overcharge, the battery will soon decay.

7, how much charge current be appropriate: In theory, the smaller the more the battery is good. But you can not order a battery charging 3 days now. GB provides low-rate charge is 0.2C (standard arbitration charge), but also to the above 1000mAh capacity battery, for example, is 200mA, then we can estimate only the battery over 5 hours to fully charge. (MAh = current capacity mA time h)

Identification of national technical supervision departments lithium capacity, high-rate charge based on 1C to 0.2C low-rate discharge, to calculate the capacity value of time, test 5 times, with capacity of 1 end of the trial. (That is, 5 times, and if the first test to pass, and the back 4 times not to) allow for a pre-test before the cycle is to 1C constant current charge to 4.2V cease, but not behind the constant pressure to 0.01 C process, not 14 hours.
