Standard Charge Test procedure and its criteria are referred as follows:
0.2C5A =940mA
Charging shall consist of charging at a 0.2C5A constant current rate until the cell reaches 4.2V. The cell shall then be charged at constant voltage of 4.2 volts while tapering the charge current. Charging shall be terminated when the charging current has tapered to 0.01 C5A . Charge time : Approx 7.0h, The cell shall demonstrate no permanent degradation when charged between 0 ºC and 45 ºC.
Standard Discharge
0.2C5A =960mA
Cells shall be discharged at a constant current of 0.2 C5A to 2.5volts @ 25º ± 5C
