1. Batteries of any size of 12V/24V can be charged. The current will be adjusted automatically.

2. The charging time depends on the true capacity of the battery. The larger the true capacity of the battery, the longer it will take to charge.

4 Charging Stage:

1. Constant Current: It means the battery voltage is lower than the set voltage of charger, then the charger supply constant charging current to maintenance both battery and charger

2. Constant Voltage: It is advanced pulse width modulation (PWM) technology. It controls the charger’s current and output voltage accurate, avoids overcharge

3. Floating Charge: When the battery is going to be full charged, the charger will stop charging, but still supply constant floating voltage and small current to the battery

4. Trickle Charge: When the battery voltage and current are approaching the set voltage and current, it will turn to trickle floating charge from automatic mode. It means full charged, but also can be charged by floating mode.

Charging operation:

1. Examine and make sure rated voltage of battery is conforming to output voltage of charger.

2. Connect correctly the charger and the battery.

3. Examine and make sure mains supply voltage is conforming to input voltage of the charger.

4. Connect mains supply and the battery, check if the indicator is on and the cooling fan is working when charging.
