All in One - Fully Automatic 6-Amp 12V Automotive Battery Charger Intelligent, smaller design with high power output. Functions as a battery charger, battery maintainer, trickle charger, and battery desulphator. Charges various 12V lead acid deep cycle batteries, including AGM, GEL, SLA, and standard lead acid types. Suitable for use with cars, trucks, SUVs, motorcycles, lawnmowers, boats, and other vehicles. Not compatible with lithium batteries. Built-in repair mode helps recover weak or inactive batteries and extend their lifespan. Utilizes high and low frequency pulse technology for effective desulphation and battery activation. Note: Cannot activate fully dead batteries or repair physically damaged cells. Features a backlit LCD display that clearly shows charging status and battery condition. Integrated thermal sensor adjusts charging based on ambient temperature to prevent overcharging in hot environments and undercharging in cold conditions. Equipped with smart memory function that retains the last used settings after power is restored. Repair mode does not include memory functionality. This device is for charging only and cannot start a vehicle. Includes multiple safety protections: overload, overvoltage, overcurrent, short circuit, reverse connection, overheating, and undervoltage protection. Charging cables contain heat-resistant copper wiring resistant to oxidation and breakage. Selectable winter and summer modes for optimal performance in varying climates. Switch to winter mode when temperatures fall below 10°C (50°F) for proper charging in cold weather. Switch to summer mode when temperatures rise above 28°C (82.4°F) to prevent overloading in warm conditions. Integrated cooling fan ensures efficient heat dissipation during extended operation, maintaining safe operating temperatures. Durable flame-retardant ABS housing provides electrical insulation, corrosion resistance, and added safety.
