Built with a pure copper coil and durable metal and ABS housing, this heavy-duty battery charger is compatible with 4–300Ah 12V and 24V lead-acid batteries, including AGM, Gel, Wet/Flooded, EFB, Calcium, MF, and deep-cycle types. It automatically detects battery voltage and provides 7-stage smart charging with FAST mode for larger batteries and SLOW trickle charging for smaller batteries. Designed for cars, trucks, motorcycles, boats, marine vehicles, RVs, and lawn mowers, it offers convenient plug-and-play automatic operation without constant monitoring.
The charger also features battery repair and desulfation functions to help restore weak, sulfated, stratified, or long-idle batteries above 3V and extend battery service life. Auto shutoff helps prevent overcharging, while Winter Mode supports more reliable charging in cold conditions. A clear LCD displays voltage, current, and charging percentage, and the unit can also be used for electrolysis projects, cast-iron restoration, rust removal, and as a 12V DC power supply. Built-in protection guards against reverse polarity, short circuits, overcharge, overheating, over-voltage, and over-current, and the charger is backed by a 3-year warranty.
