Don't get stranded by a dead battery. The Schumacher Electric BT-100 puts essential battery diagnostics in your hands, letting you test load, battery condition, and starter motor draw with a single device. Safely test 6V and 12V batteries up to 1,000 Cranking Amps (CA), run a 50-amp load test on 6V batteries and a 100-amp load test on 12V batteries, and diagnose your vehicle's charging system in minutes. From your motorcycle to your RV, the BT-100 tells you exactly what's happening under the hood so you can fix problems before they leave you stuck. Connect the heavy-duty clamps, follow the steps for your chosen test, and read the results right off the clear-view analog meter. Built with a durable steel case, a baked enamel shell, and a rubber-insulated carrying handle, this car battery tester is engineered to take a beating and keep delivering reliable results. With over 75 years of automotive power expertise behind it, the BT-100 is a battery load tester you can count on when it matters most.
