Meet the GENIUS5 – Similar to our G3500, just better. It’s 34% smaller and delivers 65% 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, lawnmowers, ATVs, lawn tractors, trucks, SUVs, boats, PWCs, classic cars, and more.
