NOCO GENIUS2D: 2A 12V Onboard Battery Charger, Maintainer and Desulfator

The NOCO GENIUS2D is a compact, direct-mount onboard battery charger designed for under-the-hood installation, delivering effortless year-round battery maintenance and reliable charging for virtually any vehicle. Securely mounting near the battery with a rugged snap-fit bracket and included self-tapping screws, the GENIUS2D becomes a permanent part of your vehicle’s charging system. It provides 2 amps of fully-automatic charging power and doubles as an advanced battery maintainer and reconditioner—not just a trickle charger. An integrated digital thermal sensor monitors ambient temperature and adjusts charging to prevent overcharging in heat or undercharging in cold weather. It intelligently detects and charges batteries as low as 1-volt, or use Force Mode to activate charging down to zero volts. Advanced repair technology automatically identifies battery sulfation and acid stratification, restoring battery performance, improving engine starts, and extending service life. Compatible with all types of lead-acid batteries—flooded, gel, AGM, and maintenance-free—the GENIUS2D is ideal for cars, trucks, SUVs, and powersports vehicles, and can be paired with NOCO’s GCP Series AC Port Plugs for convenient remote charging access. Whether parked or in daily use, the GENIUS2D keeps your battery in peak condition—24/7, worry-free.
