Introducing the GENIUS1, making it one of our most powerful, highest-performing, energy-efficient, and compact charger yet. The GENIUS1 is a 6-volt and 12-volt battery charger, battery maintainer, trickle charger, and battery desulfator, rated at 1-amp for all types of lead-acid and lithium-ion batteries, including flooded, gel, and AGM, as well as, marine and deep-cycle batteries.

• Meet the GENIUS1 – Similar to our G750, just better. It’s 35% smaller and delivers 35% more power. It’s the all-in-one solution – battery charger, battery maintainer, trickle charger, plus battery desulfator.
• 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 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.
• Restore your battery – Automatically detects battery sulfation and acid stratification to restore lost battery performance for stronger engine starts and extended battery life.
• Beyond maintenance – It’s not just a trickle charger, it’s an advanced battery maintainer. A fully-automatic, worry-free battery charger for everyday use – 24/7 – with zero overcharge.
• Compatible with all types of vehicles – Charge and maintain cars, motorcycles, lawn mowers, ATVs, lawn tractors, trucks, SUVs, boats, PWCs, classic cars, and more.
