About this item

This heavy-duty charger/maintainer auto-senses 12V or 24V batteries and charges at up to 20A, covering everything from cars and trucks to motorcycles, boats, RVs and lawn mowers. It supports AGM, GEL, Flooded, EFB, Calcium, MF and deep-cycle lead-acid batteries (not lithium/LiFePO4), with a pulse REPAIR mode that can bring back batteries as low as 3V. A dedicated Winter Mode keeps it charging properly in freezing temperatures down to -4°F (-20°C), while auto shutoff protects the battery once it's fully charged. With 10 selectable modes and a color screen, it's built with a rugged aluminum casing and copper-coil transformer for long-term reliability.
