I've used big brand name battery testers for over 3 decades now. Other than ridiculously high purchase prices, I've never given any thought to them. They just work. But this tester changed all that! Accurate readings, no gimmicks to get those readings (i.e. turn headlights on, rev engine, etc.), and it reads actual amp load.
