There shall be no such defects as deep scratch, crack, rust, discoloration or leakage, which may adversely affect the commercial value of the cell. 6.1 Standard Charge

Unless otherwise specified, “Standard Charge” shall consist of charging at constant current of 1200mA. The cell shall then be charged at constant voltage of 4.2V while tapering the charge current. Charging shall be terminated when the charging current has tapered to 50mA. For test purposes, charging shall be performed at 23ºC ± 2ºC. 6.2 Standard Discharge

“Standard Discharge” shall consist of discharging at a constant current of 480mA to 3.0V. Discharging is to be performed at 23 ºC ± 2 ºC unless otherwise noted (such as capacity versus temperature). 6.3 Initial Capacity

Cells shall be charged per 6.1 and discharged per 6.2 within 1 hour after full charge. Initial capacity shall meet the following requirement.

Initial Capacity ≥ 2380 mAh 6.4 Cycle Life

Cells shall be charged at constant current of 1200mA to 4.2V with end current of 50mA. Cells shall be discharged at constant current of 1200mA to 3.0V. Cells are to rest 10 minutes after charge and 20 minutes after discharge. A cycle is defined as one charge and one discharge. Discharge capacity shall be measured per 6.1 and 6.2 after 300 cycles.

Discharge capacity (301th Cycle) ≥ 80 % (of minimum capacity in 3.1)

6.5 Initial AC Impedance
