BatteryMINDer Model 1500: 12V 1.5 AMP Battery Charger/Maintainer/Desulfator with SmarTECHnology Designed for Cars, Trucks, Boats, Motorcycles, Snowmobiles, Jet Skis, Golf Carts, etc. FEATURING SMARTECHNOLOGY  Model 1500 features a SmarTECHnology plugn run 1.5 AMP battery charger/maintainer with full-time automatic high frequency pulse desulfator. EXTENDED BATTERY LIFE - Automatic full time desulfator reverses sulfation (a buildup of lead sulfate crystals) the primary cause of early battery failure by using a patented range of high frequencies to safely remove sulfation and recondition weak batteries. Sulfated batteries once considered beyond recovery can now be brought back to long-term useful condition. Extending battery life up to four times when compared to new batteries not being properly maintained. AMBIENT TEMPERATURE SENSOR  Installed temperature compensation precisely adjusts battery voltage based on temperature sensor readings. This ensures your battery will always be properly charged and maintained no matter what conditions it is subject to. Reverse polarity, short-circuit and over temperature protection. WORKS WITH A VARIETY OF BATTERY TYPES  Flooded, sealed, maintenance-free starter, deep cycle, Optima brand sealed AGM, and marine batteries. Model 1500 can maintain up to four batteries at a time when connected in parallel. Requires the use of Y-Connectors 27879 or 18ga (sold separately). Ideal for winterizing Cars, Trucks, Motorcycles, ATV, Boat, etc. The 90-240V AC 47-63 Hz input allows for worldwide use. FCC CERTIFIED - Certified by the California Energy Commission as meeting the current efficiency standards, which means it meets strict energy efficiency guidelines set by the US Environmental Protection Agency and the Department of Energy.
