New in Box 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.
