Battery Cell Performance Criteria

Electrical Characteristics

1)Standard Charge---->Charing the cell initially with constant current at 0.5C andthen with

constant voltage at 4.2v till charge current declines to 0.05C.

Criteria----> N.A

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.

Criteria----->≥1200mAh

3)Cycle Life----------------->Test Condition:

Charge:0.5C to 4.2v

Discharge:0.5C to 2.75v

60%or more of 1st cyle capacity at 0.5C discharge of operation

Criteria------>≥500

4)Self-discharge----------->After the standard charging,storied the cells under the condition as No.4.4

for 30days,then measured the capacity with 0.2C till 2.75v

Criteria------>Residual Capacity>90%

5)Initial impedance------>Internal resistance measured at AC 1KHz after 50%charge

Criteria------->≤80mΩ
