Charging the cell initially with constant current at 0.2C and then with constant voltage at 4.35V till charge current declines to 0.01C

2

Rated Capacity

The capacity means the discharge capacity of the cell, which is measured with discharge current of 0.2C with 2.75V cut-off voltage after standard charge.

≥680mAh
≥94%

3

Cycle Life

A battery unit shall be repeated 100 charge/discharge cycles, charged at CC-CV 0.2Cto 4.35V , laying the battery 5min, discharged at 0.2C to2.75V end voltage, After 100 cycles, recording the discharging  capacity.

100 time of discharging capacities keep

500 time of discharging capacities keep
