the current situation of mobile phone batteries are equipped

In many parts of the forum, have seen this argument

, seems to have become a classic. But the truth of certain conditions if left to become a fallacy. PANASONIC Camcorder Battery SHARP Camcorder Battery

1,12-14 hours of origin: the first generation of nickel-cadmium batteries, is the need to charge a small rate, is generally recommended charge current 1/10C, such as your battery capacity is 600mAh, then 1C is 600mA, 1/10C is 60mA . Therefore, the full power needs of more than 10 hours, the nickel-cadmium batteries, small rate charging is good.

2, the current situation of mobile phone batteries are equipped with: mainstream phones are essentially lithium-ion batteries, the latest from our impression should be 3210, with the nickel-metal hydride batteries, could not find around us like the phone with a nickel-metal hydride batteries .

3, the lithium-ion battery knowledge: we can only say that the capacity on the one hand. Measure of the capacity of a lithium-ion battery has two detection methods: 1C charge, 0.2C discharge; 0.2C charge, 0.2C discharge, regardless of what charging standard, should be standard. Because the lithium-ion battery is different from the previous nickel-cadmium batteries, 1C charging high rate already had enjoyed, but also must be acceptable to the. If a 600mAh battery with 1C charge, about 1 hour should be sufficient full, direct charge if the phone is so designed that (many of which are 0.5C-0.8C) ,12-14 hours is nonsense.

National standards required to GB/T182872000, when the constant current charge to 4.2V, switch to constant pressure, when the current drops to 0.01C when the charge is considered terminated. For example, the charging current is 0.5C, 600mAh rechargeable battery, 2 hour charge current will be reduced to 6mAh, then that is fully charged. Why is it down to 0.01C? As it is already full, this is a reflection of batteries.

In fact, on the nickel-metal hydride power, national standards have also been provided for high-rate charge and discharge of the indicator, and now I will not talk.
