Experienced mechanics know that a powerful wheeled battery charger is an essential ingredient for a well-equipped home garage. The Schumacher Electric 4-in-1 6-Volt/12-Volt 300-Amp/200-Amp Wheeled Battery Charger and Engine Starter (SC1400) features 300-Amp 12-Volt engine start, 200-Amp 6-Volt engine start, 60-Amp boost, and 6A 2A charge/maintain rates. The engine start packs more than enough power to start most cars, SUVs, and small trucks. The 60-Amp boost mode works to quickly add charge to a deeply discharged battery. Fully automatic and microprocessor controlled, the SC1400 automatically adjusts Amperage while charging and maintaining. It also offers auto Voltage detection, multi-stage charging, float mode monitoring, and reverse hook-up protection. Heavy-duty copper clAmps and 4-Gauge copper output cables ensure a reliable engine start every time.
