Discharge One cycle refer to one charge period and then one discharge period. Test condition: Charge: 0.2C to 4.2V 300 Times 5 Cycle Life Discharge: 0.2C to 2.75V The cycle life is the cycle times when the discharge capacity is about 80% of the rated capacity. After standard charging, storied at 6 Self-discharge Residual Capacity>90% 25C0.5C for 30 days, then measure the capacity as item 4. Typical: 52m After standard charging, measure the 7 Impedance internal resistance with AC1KHz Max. Charge 8 1C Current Max. 9 Discharge 1C Current Discharge 10 Cut-off 2.75V Voltage Cells must be storied at 3.6V-3.9V. During long period storage, cells should be Operating maintained every 90 days. The method Discharge:-10C ~ +55C 11 is to do a charge-discharge cycle with Temperature Charge: 0 C ~ +43C standard method, then charge to 3.7 3.9V.
