4. Setup

1. Prepare the Battery: Ensure the battery terminals are clean and free of corrosion. If necessary, clean them with a wire brush.
2. Connect the Charger to the Battery:
   • Connect the RED positive (+) clamp to the positive (+) battery terminal.
   • Connect the BLACK negative (-) clamp to the negative (-) battery terminal.

   Ensure a secure connection. If connecting to a vehicle battery, connect the negative clamp to the vehicle chassis away from the battery and fuel line if the battery is not removed from the vehicle.

3. Connect to Power: Plug the charger's AC power cord into a standard AC 100-240V, 50/60Hz electrical outlet. The charger will power on, and the LCD display will illuminate.
4. Select Charging Mode: Proceed to the Operating Instructions section to select the appropriate charging mode for your battery type.

5. Operating Instructions

Once connected, the charger will perform an intelligent detection. Use the 'MODE' touch button to cycle through the available charging programs.

5.1. Selecting a Charging Mode

Press the MODE button to select the correct charging program for your battery:

• CAR Mode: For standard 12V lead-acid automotive batteries.
• AGM Mode: For 12V AGM (Absorbent Glass Mat) batteries.
• MOTO Mode: For 12V lead-acid motorcycle batteries.
• LiFePO4 Mode: For 12V Lithium Iron Phosphate batteries.
• Repair Mode: For 12V lead-acid batteries that are sulfated or stratified. Do NOT use this mode for lithium batteries.

The selected mode will be indicated on the LCD display. The charger will automatically begin the charging process.

5.3. Intelligent Digital Display

The LCD screen provides real-time feedback on the charging process:

• Voltage (V): Displays the current battery voltage.
• Current (A): Shows the charging current.
• Temperature (°C): Indicates the internal temperature of the charger, which influences temperature compensation.
• Battery Full: Displays 'FUL' when the battery is fully charged. The charger will automatically stop charging.
• Repair Mode: Displays 'PUL' during the pulse reconditioning process.
• Error Codes: May display 'E--' or other codes for specific issues (refer to Troubleshooting).
