Standard Charge
标准充电
|
Charging the cell initially with constant current at 0.2C and then with constant voltage at 4.2V till charge current declines to 0.05C
先用0.2C恒流充电至4.2V,再恒压4.2V充电直至充电电流≤0.05C

Rated Capacity
初始容量
|
Measure discharge capacity with discharge current 0.2C to 3.0V cut-off within 1 hour after standard charge.
标准充电方式充电后,以0.2C电流放电至3V的容量
|
≥2000mAh

Cycling Life
循环寿命
|
Measure the capacity after 500 cycles of standard charge and discharge at 0.5C current to 3.0 V cut-off
标准充电方式充电后,0.2C放电至3.0V,如此循环500次后电池的剩余容量
|
≥ 80% of Rated Capacity
初始容量的80%
