※ Every month, recommend inspection every battery voltage.
Discharge （A）≥1.0C
Current (A) （A）≤0.2C 0.2C＜（A）＜1.0C
※ Every three months, recommend equalization charge for one time.
Equalization charge method:
Charge the batteries at least once every six months,

if they are stored at 25 C. Discharge: 100% rate capacity discharge.
Charging Method: Charge: Max. current 0.3CA, constant voltage 2.4-2.45V/Cell charge 24h.
※ Effect of temperature on float charge voltage: -3mV/℃/Cell.
