NOCO Genius Onboard Battery Chargers are the perfect accessories for charging and maintaining your 12-volt Marine, Starter, or Deep-Cycle batteries. Waterproof, vibration/shock resistant, and ruggedly designed, NOCO Genius Onboard Battery Chargers can be mounted directly onto a variety of applications, such as a boat, trolling motor, or generator, in addition to a full range of industrial equipment and electric vehicles. Battery activity monitoring ensures the fast, efficient, and safe charging of Gel, Wet, AGM and Maintenance Free batteries without having to worry about overcharging. Some of NOCO's most advanced charging systems, they were designed for improved battery longevity and performance.

Efficient, compact design - Utilizes a mix of industrial design and electrical engineering to create a powerful yet compact on-board battery charger that can easy to mount anywhere in your boat or equipment. High-frequency switch-mode technology efficiently converts A/C power into safe D/C power for battery charging. An on-board microcomputer precisely controls the charging, minimizing power loss with an incredibly compact form factor.

Fully submersible - Completely sealed, 100% waterproof, saltwater tested to combat corrosion, and designed to operate in extreme conditions with a rugged vibration/shock resistant construction.

Optimization - Optimizing the battery's internal specific gravity stabilizes the internal battery chemistry for increased longevity and performance.

Maintenance Plus - A powerful battery maintenance charge actively monitors and manages charge cycles, and also provides a finishing charge every 24-hours to keep your batteries fully charged with no overcharge.

Recovery - When detected, it applies a high-voltage low-current pulse charge causing battery sulfation to convert back to the active material, regaining lost battery capacity.

Interactive - Allows for precision battery charging by dynamically altering the charging process based on organic battery feedback.

Safe - Protects against adverse and abnormal conditions, like overcharging, over-current, reverse polarity, sparks, short circuits, open circuits, and overheating.

Firewall - Redundant levels of safety protection ensure your battery remains safe after a major failure.

Ignition Protected - Non-igniting and temperature controlled onboard battery charger for worry-free and safe operation (meets USCG-33 CFR 183.410 requirements).

5 Year Warranty - NOCO onboard battery chargers are built to last, so they back it up with an unbeatable warranty and unparalleled customer service.
