Setup
Mounting the Charger (Optional)
The charger can be permanently mounted using the provided screws. Choose a secure, well-ventilated location away from direct heat or moisture. Ensure sufficient space for cable connections.
Connecting to Batteries
- Ensure Power is Off: Disconnect the charger from the AC power outlet before making any battery connections.
- Choose Connectors: Select either the battery clips (alligator clamps) for temporary connections or the ring terminals for permanent installation.
- Connect to Battery Terminals:
- Connect the RED (+) charger output cable to the POSITIVE (+) battery terminal.
- Connect the BLACK (-) charger output cable to the NEGATIVE (-) battery terminal.
- Secure Connections: Ensure all connections are tight and secure. Repeat for each battery bank you intend to charge.

Operating Instructions
Starting the Charging Process
- Connect to AC Power: Once all battery connections are secure, plug the charger's AC input cable into a standard 120V AC electrical outlet.
- Automatic Detection: The charger will automatically detect the connected battery's voltage and type. The indicator lights for the detected battery type will illuminate.
- Select Charging Mode: For each bank, press the "MODE" button to cycle through the available battery types (SLA/AGM, Lithium, Calcium) until the correct mode for your battery is selected. The corresponding LED will light up.
- Charging Indication: The charging progress will be indicated by the LED segments. Each segment typically represents a percentage of charge.
- Completion: Once the battery is fully charged, all LEDs for that bank will be solid green, and the charger will switch to maintenance mode.
Force Mode (for deeply discharged batteries)
If a battery's voltage is below 1V, the charger may not automatically detect it. In such cases, use Force Mode:
- Connect the charger to the deeply discharged battery.
- Plug the charger into AC power.
- If the "12V Repair" indicator light illuminates, press and hold the "MODE" button for that bank to enter "Repair" mode. This will initiate charging for dead batteries.

| Indicator | Problem | Solution |
|---|---|---|
| Over Voltage (U+) | Input voltage exceeds 15V. Charger will not operate. | Verify the battery voltage is within the acceptable range (12V nominal). Disconnect and reconnect. |
| Bad Battery | Battery is short-circuited or severely damaged. Charger will not charge. | Inspect battery for physical damage. Test battery with a multimeter. If severely damaged, replace the battery. |
| Over Temperature | Internal temperature exceeds 100°C. Charger will power off. | Allow the charger to cool down in a well-ventilated area. Ensure no obstructions are blocking airflow. |
| Reverse Connection | Positive and negative terminals are connected incorrectly. Charger will not charge. | Immediately disconnect the charger. Reconnect the RED (+) clamp to the positive terminal and the BLACK (-) clamp to the negative terminal. |
| No Charge Indication | Charger is connected but no lights are on or charging is not initiated. | Check AC power connection. Ensure battery terminals are clean and connections are secure. For deeply discharged batteries, try Force Mode. |
