Performance Specification
4.1.1 Standard Charge
Unless otherwise specified, “Standard Charge” shall consist of charging at constant current of 1,425mA. The cell shall then be charged at constant voltage of 4.2V while tapering the charge current. Chargingshall be terminated when the charging current has tapered to 50mA. For test purposes, charging shall be performed at 25ºC ± 2ºC
4.1.2 Standard Discharge
“Standard Discharge” shall consist of discharging at a constant current of 570mA to 2.5V. Discharging is to be performed at 25 ºC ± 2 ºC unless otherwise noted (such as capacity versus temperature).
4.1.3 Fast Charge / discharge condition
Cells shall be charged at constant current of 1,000mA to 4.2V with end current of 100mA. Cells shall be discharged at constant current of 6,000mA to 2.75V. Cells are to rest 5 minutes after charge and 5 minutes after discharge.
