Get back on the road in minutes with the Stanley BC15BS 15 Amp car battery charger. With fast, high frequency technology, it delivers 3-stage charging - automatically switching from Bulk to Absorption and top-off. This battery charger is also perfect for motor homes, jet skis, lawn tractors, generators or vehicles that sit idle for months at a time. One of the most advanced chargers on the market, the Stanley Bench Charger features a digital LCD screen that displays charging status and battery status with easy to understand icons. It also includes a patented alternator check to evaluate the battery voltage under load to indicate if the alternator is maintaining battery level. While many other battery chargers require you to select various settings like battery type and size, the Stanley BC15BS 12-Volt battery charger is fully automatic and chargers up to 40% faster than other conventional chargers. There's even a patented Engine Start mode to instantly fire up your vehicle.
