Performance Specification

4.1.1 Standard Charge

Unless otherwise specified, “Standard Charge” shall consist of charging at constant current of 1,075mA.  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 25°C ± 2°c

4.1.2 Standard Discharge

“Standard Discharge” shall consist of discharging at a constant current of 430mA to 2. 75V. Discharging is to be performed at 25 °C ± 2 °C unless otherwise noted (such as capacity versus temperature).

4.1.3 Fast Charge / discharge condition

Cells shall be charged at constant current of 2, 150mA to 4.2V with end current of 107.5mA. Cells shall be discharged at constant current of 2,150mA to 2.75V. Cells are to rest 30 minutes after charge and 30 minutes after discharge.
