Features and Benefits:

• Similar to our G4, just better. It's 40% smaller and delivers 140% more power. It's the all-in-one 4-bank solution - battery charger, battery maintainer, trickle charger, plus battery desulfator.
• A four-bank battery charger maintainer rated a 8-amps - 2-amps per bank with a 40Ah capacity range - designed to charge and maintain multiple vehicles like cars, motorcycles, boats, ATVs, RVs, lawnmowers, 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.
