1. Input Data:
1.1 Input Voltage & Frequency: Input Voltage 110~230VAC,Frequency 50Hz~60Hz;
1.2 Efficiency:More than 85%(load current of charger is 3.0A);
1.3 Input current:below 2.5A, when battery is being charger
1.4 Input Surge Current: When Voltage is 120VAC,Input Surge current is less than 50A;
1.5 Input Current Leakage: when voltage is 120VAC,leak current is less than 0.25mA;
1. Check if your local mains supply conforms to charger's input voltage 110 or 230V. Then connect the charger system to a wall socket. If charger has switch with OFF position, it MUST be set to ON.

2. LED1 RED confirms AC power on, and the LED2 GREEN confirms charger connects well.

3. Connect the plug or the DC Output cord to battery terminals. LED2 RED confirms charger is charging, LED2 GREEN confirms battery fully charged. (N -> Positive ; L -> Negative ; Brown -> +ve terminal, Blue -> -ve terminal).

Output Charging Characteristic:
Note: This chart is based on 4 12V20Ah battery. Charging time should be determined by battery amp hour capacity.


1. This charger is designed for Lead Acid or Silicon type batteries only.

2. Avoid charging the wrong type of battery.

3. The battery may be damaged if LED2 cannot be changed to green after a long time of charging.

4. Always place the charger in well-ventilated and dry environments.
