- Meet the GENIUS2 - Similar to our G1100, just better. It's 30% smaller and delivers 140% 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.
