4) The battery need to be charged every 6 months if out of use

5) Keep the battery against dropping, turning over and serious stacking during loading.

3. Product Performance

Testing Conditions: Ambient Temperature: 25±5℃ (68℉~86℉); Huminity:45%~75%.

Normal charge:Charge battery under CC(0.33C)/CV(58.4V) mode until over charge protection or the charge current reduce to 0.05C, and then rest for 1h.

NO Items Criterion Condition
3.1 Normal Capacity 40Ah After Normal charge, discharge @0.33C current to the end of discharge voltage.
3.2 Internal Impedance ≤50mΩ @50% SOC @1kHz AC internal resistance test instrument.
3.3 Cycle life @DOD100% ≥2000 cycles After Normal charge,discharge @0.33C current to the end of discharge voltage. Repeat above process until discharge capacity reduce to 80% of initial value.
