5. Operating Instructions

5.1 Automatic Charging

After connecting the charger to the battery and AC power, the charger will automatically detect the battery type (12V or 24V) and current temperature. It will then enter the appropriate charging mode.

• Temperature Compensation: The charger automatically adjusts charging voltage and current based on ambient temperature. Below -10°C, it enters Winter Mode; above 26°C, it enters Summer Mode.
• Automatic Shut-off: The charger will automatically stop charging when the battery is fully charged to prevent overcharging.

5.2 Manual Mode Selection

Press the "Mode Selection" touch button to cycle through the available charging modes:

• Vehicle Mode: For standard car batteries.
• AGM/GEL Mode: For AGM or GEL type batteries, often found in start-stop vehicles.
• Motorcycle Mode: For smaller capacity motorcycle batteries.
• Repair Mode: For desulfation and reconditioning of old, weak, or idle batteries.

5.3 Pulse Repair Function

The pulse repair function is designed to dissolve sulfuric acid crystals that can build up on battery lead plates, which can reduce battery capacity and lifespan. To use this function:

1. Connect the charger to the battery as described in Section 4.
2. Select "Repair Mode" using the Mode Selection button.
3. The charger will begin the repair process. This can take several hours or even a day, depending on the battery's condition. Monitor the display for progress.
4. Once the repair process is complete, the charger may switch to a maintenance charge or indicate completion.

Note: The repair function may not be able to restore severely damaged or dead batteries.
