About this product

The GENIUS5 is the ultimate all-in-one solution for battery charging, maintenance, and restoration, delivering 34% more power in a 65% smaller design compared to its predecessor, the G3500. Designed for 6-volt and 12-volt lead-acid (AGM, gel, flooded, and deep-cycle) and lithium-ion (LiFePO4) batteries (up to 120 amp-hours), it is compatible with a vast array of vehicles, such as cars, automobiles, motorcycles, dirt bikes, scooters, mopeds, lawn mowers, ATVs, UTVs, tractors, trucks, SUVs, RVs, campers, trailers, boats, PWCs, jet skis, snowmobiles, golf carts, classic cars, and more; including automotive brands like BMW, Mercedes-Benz, Porsche, Bentley, Maserati, Lexus, Audi, Ford, Chevrolet, Corvette, Cadillac, Prius, Toyota, Subaru, Nissan, powersport vehicles such as Harley-Davidson, Honda, Yamaha, Kawasaki, Ducati, Indian, KTM, Husqvarna, Vespa, Polaris, Seadoo, as well as lawn and garden vehicles such as John Deere, Kubota, Toro and more. Featuring an integrated thermal sensor, the GENIUS5 adjusts its charging profile based on ambient temperature, ensuring optimal performance by eliminating the risk of overcharging in hot climates and undercharging in cold ones. It's capable of charging batteries as low as 1 volt and offers a Force Mode for manually charging completely dead batteries (as low as zero volts). With precision pulse charging, the GENIUS5 restores battery health by reversing sulfation and acid stratification, improving performance and extending battery life. Its advanced monitoring system allows for safe, indefinite connection, making it perfect for long-term maintenance. The package includes a 5A charger (120-240VAC), 72-inch AC cable, 80-inch DC cable with battery clamps, and integrated eyelet terminals, mounting bracket and screws, all backed by a three-year warranty. Proudly designed in the USA, the GENIUS5 combines power, reliability, and convenience in a compact design to keep your batteries ready for whatever lies ahead.
