Activation of a new battery, charging 12 hours correct misunderstandings 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. ? ? 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, now with mobile phones and digital camera batteries: The mainstream mobile phones are essentially lithium-ion battery, the latest from our impression should be 3210, with the nickel-metal hydride batteries, could not find around us like nickel hydrogen battery cell phone. Digital Camera Ni-MH and Li-ion batteries each half. ? ? 3, 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 a high rate already had enjoyed, but also must be receptive of the idea. 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. ? ? to GB/T18287 2000 under the national standard, 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. Laptop BatteryACER Laptop Battery Dell Laptop Battery HP Laptop Battery TOSHIBA Laptop Battery
