A four-bank on-board battery charger rated at 40-amps for 12-volt batteries, including marine, boat, starter, and deep-cycle batteries. Charging modes - Independently charge and control each battery bank with selectable charging modes - including 12V, 12V AGM, 12V Lithium, and 12V Repair Mode - for all types of lead-acid and 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. Redefined mounting - A simplified mounting system allows for quick and easy installations in any direction - even up-side-down - with an integrated anti-vibration backing to isolate shock, vibration, and noise. Designed for water - A fully-sealed and waterproof onboard battery charger with an ingress protection rating of IP68, but has survived brutal life cycle testing, including thousands of hours underwater.

We use this charger for our Seadoo scuba scooter batteries, and it’s been a game changer. Not only did it charge and maintain our batteries, but it also revived a couple that were thought to be "dead" by other chargers. It provides just the right voltage to get them back to life. Super easy to use with helpful modes like force charge and repair. While it’s not cheap, it’s already saved us money by restoring old batteries and keeping the good ones in top shape. Worth every penny!

This 3-bank battery charger works exactly as described. I tested it by charging two batteries of different sizes at the same time, and it handled both without issue. It’s ideal for boats with three 12V batteries stacked to provide the right amount of power. Very reliable!

Hubby loves this charger. He only has 2 batteries but likes that this one will charge 3 if he needs it. Highly recommend it.
