5.2 Mode Selection

Press the "MODE SELECTION" button to cycle through the available charging modes. The charger has an intelligent memory function that defaults to the last used mode after a power cycle.

• Car Mode (Standard): For standard 12V/24V lead-acid batteries in cars, trucks, SUVs.
• AGM/GEL Mode: Specifically optimized for AGM and GEL batteries.
• Motorcycle Mode (Moto): For smaller 12V batteries found in motorcycles, lawnmowers, etc.
• Repair Mode: An advanced mode designed to help recover old, idle, or sulfated batteries and extend their life. This mode uses high-frequency and low-frequency pulse technology.

Note: Repair mode cannot activate a completely dead battery or repair a physically damaged battery. It is not for Lithium batteries.

5.3 Temperature Adaptive Charging

The integrated thermal sensor detects the ambient temperature and automatically adjusts the charging voltage and current. This prevents over-charging in hot climates and under-charging in cold climates, ensuring optimal battery health and charging efficiency.
