One charger to rule them all! The Genius 1 Allround 6 / 12 V Lithium / Gel / Lead Smart Battery Charger, can charge every battery! But is does not stop there!

Introducing the all-new GENIUS1, one of our most powerful, highest-performing, energy-efficient, and compact chargers yet. The GENIUS1 is a 6-volt and 12-volt battery charger, battery maintainer, and battery desulfator rated at 1-amp for lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries. 

• Meet the GENIUS1 - Similar to our G750, just better. It's 25% smaller and delivers over 35% 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.
