Cycles Life

Under the temperature of 25±2°℃,charge the cell with 1.0C
when the voltage reaches up to 4.0V charge with constant
voltage until the current≤0.05C,then stop charging,rest for
0.5h,then discharge with 1.0C to 2.0V.Cycle with the above
mode,the test shall be terminated when Discharging Capacity
<70%of Initial Capacity in three consecutive cycles.

≥3000Cycles
