新电池激活（New battery activated） In many places of the forum, see this argument, seems to have become a classic. But if you leave a particular truth The condition becomes false. The origin of 1, 12-14 hour: the first generation of the nickel cadmium battery, charging rate is small, generally recommended 1/ charging current 10C, for example, your battery capacity is 600mAh, then 1C is 600mA, 1/10C is 60mA. Therefore, full charge takes more than 10 hours, for nickel cadmium batteries, small power charge. The battery 2, at present the mainstream mobile phone: mobile phone is basically a lithium ion battery, from our recent impression should be 3210, with the NiMH batteries around us cant seem to find a mobile phone for nickel hydrogen batteries. 3, lithium ion battery knowledge: we only said a capacity. A measure of the capacity of the lithium ion battery has two detection methods: 1C 0.2C 0.2C, charging; charging, 0.2C, no matter what the charging standard, should be standard. Because the nickel cadmium battery lithium ion battery is different from the previous, high rate of 1C has been charged can usually accept, but also must be accepted. If a 600mAh battery with 1C charging, 1 hours should be enough, if the mobile phone charge is designed (many of which are 0.5C-0.8C, 12-14 hours is groundless statement). GB/T18287 2000 stipulated in national standards, when the constant current charge to 4.2V, turn the constant voltage, when the current drops to 0.01 C that charge termination. For example, the charging current is 0.5C, 600mAh battery, 2 hours charging current will be reduced to 6mAh, then that charging is completed. Why would drop to 0.01C? Because it is full, this is a reflection of the electrical core. The nickel metal hydride power, national standard has also provided high rate discharge indicator. 4, what is activated? The lithium ion battery itself is live, if the design capacity of 600mAh, although I charge 2 hours full, then can get the discharge capacity of 60
