    • MEET THE GENIUS2D A direct-mount onboard battery charger for an under-the-hood battery charging. It's the all-in-one charging solution - battery charger, battery maintainer, trickle charger, plus desulfator.
    • DO MORE WITH GENIUS Designed for 12-volt lead-acid (AGM, Gel, SLA, VRLA) batteries, including flooded, maintenance-free, deep-cycle, marine and RV batteries.
    • DIRECT MOUNT Securely attaches near the battery using a durable snap-fit mounting bracket and installs easily into most surfaces with truss-head self-tapping screws for a hassle-free, reliable setup.
    • ENJOY PRECISION CHARGING An integrated thermal sensor dynamically adjusts the charge based on ambient temperature, preventing overcharging in hot weather and undercharging in cold, ensuring optimal battery performance.
    • CHARGE DEAD BATTERIES Charge batteries from as low as 1 volt, or use Force Mode to manually charge completely dead batteries down to zero volts. Perfect for recovering deeply discharged or neglected batteries.
    • BEYOND MAINTENANCE Keep your battery fully charged without worrying about overcharging. Our smart charger constantly monitors the battery, allowing you to leave it connected safely - indefinitely - for worry-free maintenance.
    • RESTORE YOUR BATTERY Precision pulse charging automatically detects and reverses battery sulfation and acid stratification, restoring your battery's health for improved performance and extended lifespan.
