Cycle number Charge Stand in charged Condition Discharge
1 28mA for 16h None 70mA for 2h20min
2-48 70mA for 3h10min None 70mA for 2h20min

50 28mA for 16h 1h to 4h 56mA to 1.0V/cell
1. Befor the endurance in cycles test, the cell shall be discharged at 56mA to a final voltage of
1.0V/cell.
2.The following endurance test shall then be carried out, in an ambient temperature of 20℃±5℃.
5.3 Humidity
The battery shall not leak during the 14 days which it is submitted to the condition
of a temperature of 33±3℃ and a relative humidity of 80±5%.
6. OTHERS
6.1 We recommend you to set the cut-off voltage at 1.0V/cell.
6.2 If the cut-off voltage is above 1.1V/cell, the battery may be underutilized resulting
insufficient use of the available capacity.
6.3 If it is below 1.0V/cell the battery may have discharge or reverse charge to the cell.
