NOCO GENIUS5 — 5 Amp Smart Battery Charger, Maintainer & Desulfator

Keep your batteries healthy, maintained, and ready for action with the NOCO GENIUS5 — a compact yet powerful charger designed for a wide range of battery types, from vehicles to marine crafts, RVs, lawn equipment, and more.

🔋 Key Features & Benefits

• Universal 6 V / 12 V support: Works with most lead-acid battery chemistries (flooded, gel, AGM, maintenance-free), deep-cycle, marine, and even lithium-ion (LiFePO₄) batteries — offering broad compatibility for cars, motorcycles, boats, ATVs, lawnmowers and more. 

• 5-amp intelligent charging: Provides efficient, stable charging for battery capacities up to ~120 Ah — powerful enough for standard vehicle batteries but gentle enough for maintenance and long-term storage.

• Automatic maintenance & desulfation: Multi-stage smart charging automatically switches from bulk to absorption and float/maintenance modes. It also includes a desulfation / “repair” mode to help rejuvenate sulfated or neglected batteries.

• Revive deeply discharged batteries: The GENIUS5 can detect and charge batteries as low as 1 volt. If needed, “Force Mode” lets you manually revive even completely dead batteries down to 0 V.

• Temperature-compensated for year-round charging: Built-in thermal sensor adjusts the charge rate depending on ambient temperature — safeguarding against over- or under-charging in cold or hot environments. 

• Compact, energy-efficient design: The unit is significantly smaller than older chargers (about 34% smaller than its predecessor), yet delivers up to 65% more power — making it easy to store in a garage or workshop without clutter. 

• Safe and user-friendly: Automatic operation — just plug in, connect to battery, and let the charger manage the rest. Includes safeguards such as reverse-polarity protection and overcharge prevention.

🚗 Why Choose GENIUS5 — Ideal For:

• Car, truck, or SUV owners who want a reliable charger/maintainer for regular battery maintenance.

• Motorcycle, ATV, lawn equipment, or seasonal-use vehicle owners who need to maintain batteries during storage or long idle periods.

• Marine, RV, or power-sport users who want a charger compatible with multiple battery types.

• Anyone who wants a small, efficient, and smart charger that can revive neglected batteries and keep them in top condition — without risk of overcharging or damaging the battery.

A smart upgrade from standard trickle chargers — the NOCO GENIUS5 ensures your batteries stay healthy, powerful, and ready to go, whenever you need them.
