Meet the GENIUS2D, one of our most powerful, highest-performing, energy-efficient, and compact onboard universal battery chargers yet. The GENIUS2D is a 2-amp (28-watt) - 100-240VAC 50-60Hz - 12-volt heavy-duty battery charger, battery maintainer, trickle charger, float charger, and battery desulfator for up to 40 amp-hours. It's designed to charge and maintain all types of sealed lead-acid batteries, including flooded, gel, maintenance-free, AGM, SLA, VRLA, as well as automotive, marine, RV, powersports, and deep-cycle batteries. Its advanced battery repair regenerator mode uses slow pulse reconditioner technology to automatically detect battery sulfation and acid stratification, restoring lost battery performance for extended battery life. It can be mounted almost anywhere - under the hood, engine compartments, garage - to charge and maintain any battery. Its next-generation charging regime utilizes fast charging microprocessor technology to rapidly recharge batteries without any manual intervention. It's a completely automatic, worry-free, professional, and commercial-grade intelligent battery charger with zero overcharge. Designed to be dual purpose - both indoors and outdoors - providing weatherproof and waterproof protection from the outside elements during any time of the year, including winter. A digital display provides the charging status and tests diagnostics for multiple conditions such as a dead battery, bad battery, reverse polarity, and more. It comes with a 24-inch AC cable and a 24-inch DC cable with 3/8-inch eyelet terminals designed to be securely mounted near your battery. And it's compatible with all types of gas and diesel vehicles, including cars, automobiles, lawn mowers, ATVs, UTVs, lawn tractors, trailers, trucks, SUVs, boats, campers, RVs, jet skis, PWCs, wave runners, snowmobiles, 4-wheelers, generators, golf carts, classic cars, including BMW, Mercedes-Benz, Porsche, Bentley, Maserati, Lexus, VW, Audi, Ford, Chevrolet, Corvette, Cadillac, Jeep, Prius, Toyota, Subaru, Nissan, Honda, Polaris, Seadoo, John Deere and more. En español (ES): Conozca el GENIUS2D, uno de nuestros cargadores de batería universales a bordo más potentes, de mayor rendimiento, de bajo consumo y compactos hasta el momento. El GENIUS2D es un cargador de batería de servicio pesado de 2 amperios (28 vatios) - 100-240 VCA 50-60 Hz - 12 voltios, mantenedor de batería, cargador lento, cargador flotante y desulfatador de batería de hasta 40 amperios-hora. Está diseñado para cargar y mantener todo tipo de baterías selladas de plomo-ácido, incluidas las inundadas, de gel, sin mantenimiento, AGM, SLA, VRLA, así como baterías automotrices, marinas, de vehículos recreativos, de deportes motorizados y de ciclo profundo. Su modo regenerador de reparación de batería avanzado utiliza tecnología de reacondicionamiento de pulso lento para detectar automáticamente la sulfatación de la batería y la estratificación ácida, restaurando el rendimiento perdido de la batería para prolongar la vida útil de la batería. Se puede montar en casi cualquier lugar, debajo del capó, en los compartimentos del motor, en el garaje, para cargar y mantener cualquier batería. Su régimen de carga de próxima generación utiliza tecnología de microprocesador de carga rápida para recargar rápidamente las baterías sin ninguna intervención manual. Es un cargador de batería inteligente completamente automático, sin preocupaciones, profesional y de grado comercial sin sobrecarga. Diseñado para ser de doble propósito, tanto en interiores como en exteriores, brindando protección impermeable y resistente a la intemperie contra los elementos externos durante cualquier época del año, incluido el invierno. Una pantalla digital proporciona el estado de carga y prueba los diagnósticos para múltiples condiciones, como batería agotada, batería defectuosa, polaridad inversa y más. Viene con un cable de CA de 24 pulgadas y un cable de CC de 24 pulgadas con terminales de ojal de 3/8 de pu Meet the GENIUS2D - A direct-mount onboard battery charger for an under-the-hood battery charging. It's the all-in-one universal charging solution - battery charger, battery maintainer, trickle charger, float charger, plus battery desulfator.
