4.1 Test condition
4.1.1 Rated Charge
Unless otherwise specified, “Rated Charge” shall consist of charging at constant current of 0.5C(1500mA). The cell shall then be charged at constant voltage of 4.20V 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 25ºC.
4.1.2 Rated Discharge
“Rated Discharge” shall consist of discharging at a constant current of 0.2C(600mA) to 1.50V. Discharging is to be performed at 25ºC unless otherwise noted (such as capacity versus temperature). Charging and discharging are to be performed at 25ºC
4.1.3 Standard Charge / Discharge condition
Cells shall be charged at constant current of 1.0C(3000mA) to 4.2V with end current of 50mA. Cells shall be discharged at constant current of 3.33C(10000mA) and 6.67C(20000mA) to 2.5V. unless otherwise noted (such as capacity versus temperature). Cells are to rest 10 minutes after charge and 45 minutes after discharge at 25ºC.
