Genius On-Board Battery Charger

A multi-functional design that allows you to charge in more ways. Effortlessly charge multiple battery voltages (6-volt and 12-volt lead-acid and lithium-ion batteries) chemistries (Flooded, gel, maintenance-free, and AGM batteries) and types (Starter, deep-cycle, marine, powersport, and more). Charges batteries as low as 1-volt. Or use the all-new force mode that allows you to take control and manually begin charging dead batteries down to zero volts. Automatically detects sulfation/acid stratification. Designed to fit battery terminals of any shape and size. Capacity range: Up to 30 amp-hours.
