Brand NEW in Original Box. Please note it is for 24Volt Systems. Pulse Genetech Nanopulser Desulfators condition batteries for better performance while maintaining higher capacities and longer battery life. They apply a weak but sharp electrical pulse that inhibits the buildup of hard lead-sulfate crystals while decomposing existing crystals without damaging the battery plates. They are ideal for use on boats, RVs, cars and trucks, construction equipment, forklifts, golf carts, and more. They are safe for regular flooded, AGM or GEL lead acid batteries and can revive older, sulfated batteries.
