2-Amp Battery Charger, Battery Maintainer and Battery Desulfator

Introducing the all-new GENIUS2, one of our most powerful, highest-performing, energy-efficient, and compact chargers yet. The GENIUS2 is a 6-volt and 12-volt battery charger, battery maintainer, and battery desulfator rated at 2-amps for lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries.

Meet the GENIUS2 - Similar to the G1100, just better. It's 30% smaller and delivers 140% more power. And it's simpler and easier to use than ever before. Do more with Genius - Designed for 6-volt and 12-volt lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries. Enjoy precision charging - An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates.

Charge dead batteries - Charges dead 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. Simple to set up and use - Plug-in, connect to the battery, select a charge mode, and start charging your battery. A fully-automatic, worry-free battery charger for year-round use. Restore your battery - Detects sulfation and acid stratification and restores lost performance for stronger engine starts and extended battery life.

Compatible with all types of vehicles - Charge and maintain cars, motorcycles, lawnmowers, ATVs, tractors, trucks, SUVs, boats, classic cars, hot rods, and more - you name it.
