6.1 Electrical characteristics  
NO.ItemsTest Method and ConditionCriteria 
1Standard ChargeCharging the cell initially with constant current at 0.2C and then with constant voltage at 4.2V till charge current declines to 0.02C
2Rated CapacityThe capacity means the discharge capacity of the cell, which is measured with discharge current of 0.2C with 3.0V cut-off voltage after standard charge.
3Cycle LifeTest condition:
Charge:  0.2C to 4.2V
Discharge: 0.2C to3.0V
80% or more of 1st cycle capacity at 0.2C discharge of Operation
4Self-dischargeAfter the standard charging, storied the cells under the condition as No.6.4 for28 days, then measured the capacity with 0.2C till 3.0V
Residual capacity >90%
 5Initial impedance of cellInternal resistance measured at AC 1KHz after 50% charge    
,AC 1KHz
1. According to item 4.1.1, at 25±5ºC.
2. Capacity comparison at each temperature, measured with constant discharge current 0.2C with 3.0V cut-off. Percentage as an index of the capacity compared with 100% at 25ºC
-20ºC: ≥50%
25ºC: 100%
