• [12V/24V AUTOMATIC DETECTION & REPAIR] Instantly identifies 12V or 24V systems upon connection. Features a pulse Repair Mode to help activate old, idle, or stratified batteries and restore lost performance. (Note: Cannot activate a totally dead battery with 0V).
• [FORCED CHARGING MODE]if the voltage of a 24V battery is too low and mistakenly recognized as a 12V battery, you can manually activate the forced charging mode (refer to the manual or contact customer service)
