PERFORMANCE SPECIFICATION
4.1.1 Standard Charge
Unless otherwise specified, “Standard Charge” shall consist of charging at constant current of 1,250mA.
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 25ºC ± 2ºC.
4.1.2 Standard Discharge
“Standard Discharge” shall consist of discharging at a constant current of 520mA to 2.75V. 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 1,250mA to 4.2V with end current of 125mA. Cells shall be
discharged at constant current of 2,500mA to 3.0V. Cells are to rest 30 minutes after charge and 30
minutes after discharge.
