Overview

The NOCO Genius GEN5X3 is a compact and powerful 12V 15A 3-Bank onboard marine battery charger and maintainer. The GEN5X3 is designed to safely support 12-volt lead-acid and lithium-ion batteries of multiple chemistries such as flooded, gel, maintenance-free and AGM batteries, as well as multiple battery types such as starter, deep-cycle, marine, and more. This 15-amp charger is ideal for boats, pontoons, jet skis, fishing vessels, sailboats, motorboats, and other onboard applications as it has a fully-sealed, IP68 waterproof design. A simplified mounting system allows for quick and easy installations in any direction, and has an integrated anti-vibration backing to isolate shock, vibration, and noise. The GEN5X3 also features selectable charging modes—including 12V, 12V AGM, 12V Lithium, and 12V Repair Mode—and automatically detects sulfation and acid stratification, delivering optimized performance to support different battery types and extend battery life. This fully automatic, multi-chemistry charger includes an integrated thermal sensor that adjusts output based on ambient temperature, preventing overcharging in hot climates and undercharging in cold ones. Charge batteries from as low as 1V, or for dead battery recovery, Force Mode allows manual charging from 0V, enabling you to revive batteries that most chargers cannot detect. Built for demanding environments, the GEN5X3 delivers rugged, reliable, and safe charging for marine battery applications.
