Constant-current Constant-

voltage Controlled Charge

Phase 1 (Constant-current)

constant current charge at 24~31.2

amperes until the battery voltage measures

between 9.52~9.72 V/Battery(25°C) on charge

voltage.

Phase 2 (Constant-voltage)

constant voltage charge at 9.52~9.72 V/Battery(25°C) until

the current measures between 2.4~7.2 amperes.

Phase 3 (Constant-current)

constant current charge at 2.4~7.2 amperes until the battery voltage

measures between 10~10.8 V/battery(25°C) or until dV/dt reaches to less

than 0.035.

* END OF CHARGE at 110~120% of AH returned.

* Note : Charging condition(Voltage,Current, Time) will very depending on battery

size, charger(Charging Type, output) depth of discharge and temperchure.
