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.

    Best Trickle Charger I own

    I own several trickle chargers, and by far this is the best one. AGM, lead acid, it does all batteries. Highly Recommend

    Great product for EV/Plug-ins 12vdc.

    Great product for EV/Plug-ins for those who don't drive enough to keep their 12 volt dc AGM battery charged. AGM batteries are different then lead acid of times gone by.
