10ºC~15ºC 0.2C Max
15ºC~25ºC 0.5C Max
25ºC~45ºC 0.5C Max
Standard Charging method CC/CV 0.2CCC(constant current) charge to, thenCV(constant voltage 4.2V) chargetill charge current decline to ≤ 0.05C
Cycle Life ³500 Times
One cycle refer to one charge period and then one discharge period.
Test condition:
Charge:0.2C to 4.2V
Discharge: 0.2C to 2.8V
The cycle life is the cycle times when the discharge capacity is about60% of the rated capacity.
Initial
Impedance
£380mΩ Internal resistance measured at AC 1KHz after50% charge
Max. Discharge Current 0.5C
Discharge Cut-off Voltage 3.0V
