循环寿命
Cycle life
在环境温度为 25℃±2℃条件下，以 3A 充电，当电池端电压
达到 4.2V 时，改为恒压充电，截止电流为 0.05C，总时间
不大于 8h，搁置 0.5h，然后以 3A 电流放电到终止电压，放
电结束后，搁置 15min，再进行下一个充放电循环。
Charge the battery at 3A at ambient temperature of 25 ℃
±2 ℃ until voltage reaches 4.2V, and then charge at
constant current to current less than or equal to
0.05C.Total charging time should not be more than 8
hours. After that, store the battery for 0.5 hour and
discharge at 0.5C to the cut-off voltage. When the
discharge is finished, store the battery for 15 minutes
before proceeding to the next charge and discharge cycle.
