4A 2-Bank Battery Charger

2-Bank, 4-Amp Battery Charger, Battery Maintainer, and Battery Desulfator Introducing the all-new GENIUS2X2, making it one of our most powerful, highest-performing, energy-efficient, and compact charger yet. The GENIUS2X2 is a 6-volt and 12-volt two-bank battery charger, battery maintainer, trickle charger, and battery desulfator. It's rated at 4-amps (2-amps per bank) for all types of lead-acid and lithium-ion batteries, including flooded, gel, and AGM, as well as marine and deep-cycle batteries. A two-bank battery charger, battery maintainer, trickle charger, and battery desulfator - the perfect all-in-one solution for battery maintenance. A two-bank battery charger maintainer rated a 4-amps - 2-amps per bank with a 40Ah capacity range - designed to charge and maintain multiple vehicles like cars, motorcycles, boats, ATVs, RVs, lawnmowers, lawn tractors, trucks, and more. 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. 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. 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. Automatically detects battery sulfation and acid stratification to restore lost battery performance for stronger engine starts and extended battery life. 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.
