Introducing the revolutionary NOCO® GENIUS10 6V/12V 10A Smart Battery Charger, Maintainer, and Desulfator. The GENIUS10 stands out as 1 of NOCO's most powerful, highest-performing, energy-efficient, and compact chargers yet. The GENIUS10 serves up a 6V or 12V battery charger, battery maintainer, and battery desulfator rated at 10A for lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free batteries plus lithium-ion for unparalleled versatility. Precision charging integrates a thermal sensor that detects the ambient temperature and alters the charge to eliminate over-charging in hot climates or under-charging in cold climates. The GENIUS10 can charge dead batteries as low as 1V. Or, you can use the game-changing Force Mode that lets you take control and manually begin charging dead batteries at down to 0V. Fully automatic, worry-free operation means you can leave it for year-round use. Beyond charging and maintaining your battery, this NOCO GENIUS detects sulfation and acid stratification and restores lost performance for stronger engine starts and extended battery life.
