4.2 TEST METHOD AND CELL PERFORMANCES
4.2.1 APPEARANCE
No conspicuous stretches which influence the value of the battery.
4.2.2 CAPACITY
Charge with 0.1C for 14 hours then discharge with 0.2C to the end-voltage 1.0 V/unit,
the capacity shall be more than 1200 mAh.
4.2.3 OPEN-CIRCUIT VOLTAGE
The open-circuit voltage within one hour after full charge shall be more than 1.25V/unit.
4.2.4 INTERNAL IMPEDANCE
Within one hour after full charge, the internal impedance shall be less than 30 mΩ/cell.
4.2.5 HIGH RATE DISCHARGE
The capacity shall be more than 1080 mAh with the constant discharge current of
1200mA to the end voltage of 1.0V after the battery is fully charged.
4.2.6 SELF-DISCHARGE
The capacity shall be more than 720 mAh after the storage of 28 days for the fully
charged battery.
4.2.7 OVER-CHARGE
