Operating Modes

The COREBOX charger offers various modes to suit different battery types and charging needs. Use the "Mode Switch Button" (indicated by 'M' or gear icon on the display) to cycle through the available modes.

• STD (Standard): For ordinary lead-acid batteries and maintenance-free batteries.
• AGM/GEL: For AGM and GEL batteries.
• Motorcycle: Optimized for motorcycle batteries.
• LiFePO4: Specifically for Lithium Iron Phosphate batteries.
• Repair: This function is for batteries that cannot be charged normally due to sulfation or acid stratification. The charger uses pulse technology to attempt to restore these batteries.
• Supply Mode: Press the mode switch button for 3 seconds. When the "SUPPLY" indicator appears and the screen displays "SUP", the supply mode is on. This mode can provide power to any DC12V devices such as a car refrigerator. Press the mode switch button again to exit supply mode.

The charger also features automatic seasonal modes (Summer/Winter) based on ambient temperature, adjusting charging parameters accordingly.
