Performance Specification
4.1.1 Standard Charge
Unless otherwise specified, “Standard Charge” shall consist of charging at constant current of 0.5C. 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.
4.1.2 Standard Discharge
“Standard Discharge” shall consist of discharging at a constant current of 0.2C to 3.0V. Discharging is to be performed at 23 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 0.5C to 4.2V with end current of 50mA. Cells shall bedischarged at constant current of 0.5C to 3.0V. Cells are to rest 10 minutes after charge and 20 minutes after discharge.
