Product Description

The 12V 30A battery charger features an innovative boost-charge feature; this helps activate a battery with low voltage. The boost-charge feature will “wake up” a weak or flat battery to a suitable recharging voltage.

Product Detail

KOSUN AC to DC high quality 12V 30A battery charger choose the aluminium case for the durable function and cooling for charger for long time working.The 3 stage of smart charger as follow:
Stage 1 boost charge(constant current) supply the maximum rated current of the charger at a constant rate until the battery reaches the final charging voltage(absorption voltage) this ensures,that the battery is charged to approximately 80% capacity in the shortest amount of time.
Stage 2 absorption charge(constant voltage) the charging voltage is held constant for the remaining 20% capacity of the battery,and the current is gradually decreased as the battery approaches full charge;
Stage 3 Float charge:once the battery has reached full charge,the charger voltage is then lowered and held constant.This prevents over charging the battery and prolongs the life and the stage is often referred to as a maintenance mode,rather than charging a battery,it keeps an already charged battery from discharging while providing power to any additional loads connected to the battery,such as fridges and lights.
