PERFORMANCE SPECIFICATION
4.1.1 Standard Charge
Unless otherwise specified, “Standard Charge” shall consist of charging at constant current of 1500mA.
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 600mA to 2.5V. 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 4000mA to 4.2V with end current of 100mA. Cells shall be
discharged at constant current of 10000mA and 20000mA to 2.5V. Cells are to rest 10 minutes after
charge and 30 minutes after discharge.
