6.2 Mode Selection

Press the MODE button to cycle through the available charging modes:

• Vehicle Mode: For standard 12V car, truck, and SUV batteries.
• AGM/GEL Mode: Specifically for AGM and GEL type 12V batteries.
• Motorcycle Mode: For 12V motorcycle batteries.
• Repair Mode: Used for desulfating and reconditioning old, sulfated, or deeply discharged batteries.

6.3 Charging Process and Display Indicators

During charging, the LCD will display various parameters:

• Temperature: Current ambient temperature.
• Voltage: Real-time battery voltage.
• Current: Charging current being delivered to the battery.
• Charging Status: Battery icon will show progress.
• FULL: Indicates the battery is fully charged. The charger will automatically switch to trickle charge/maintenance mode.

6.4 Pulse Repair Function

If your battery is old, has reduced endurance, or has been idle for a long time, the Repair Mode can help. Select this mode to attempt to activate and maintain under-voltage batteries by reducing sulfation and acid stratification.
