Schumacher Electric 100A Car Battery Load Tester and Voltmeter, Charging System Diagnosis, 6V/12V Sport, Auto, and Marine Batteries, BT-100

I bought my BT-100 Battery Load Tester aproximately 1 month ago and was really pleased with overall quality and design of the unit, it is easy to use, is very well constructed and will I'm sure be a treasured piece of my electrical arsenal of test equipment for many years to come. Yes there are cheaper devices on the market but after looking at 3 or 4 others I decided to go for the better quality albeit slightly pricier Schumacher BT-100 and am very pleased with it's performance, quality and ease of use.

I'm a do it yourselfer and responsible for keeping our three vehicles in top running order. Over the years I used a basic multi-meter to monitor battery/alternator voltage. However, I was never was able to perform a load test unless I had my wife or son crank while I read multi-meter. I recently had an a cranking issue with one of the vehicles. Although the battery reflected 12.4 volts(engine not running) it simply wouldn't crank. After checking alternator output and ruling out starter, I realized that I had experienced this issue before...weak/damaged battery. Rather than waiting for my wife to return from work to perform the load test I decided to buy the the BT-100 at a local store. Bought the BT100 and charged the battery. Hooked up the BT-100 and performed the load test. Just as I thought, the battery was a goner. The BT100 is a vital tool to assist any user with keeping their auto in top running shape. Performing easy maintenance testing using the BT-100 will prevent potential no starts down the road. It's easy to use this tool. I highly recommend the BT-100.
