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. Suitable 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 35% smaller and delivers 35% more power. And it’s simpler and easier to use than ever before.
• Do more with Genius. Designed for 12-volt 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 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, ATVs, boats, classic cars, and more – you name it.

Ultimate versatility.

Four battery chargers in one.

Other brands require a separate battery charger for AGM batteries, and yet another for lithium-ion batteries. With our versatile multi-purpose battery chargers, as your needs and vehicles change, your charger won’t. With a simple push of a button, you’ll have the power to switch between charging modes with one battery charger.
