This tester is well built. It is accurate and does exactly what it is supposed to do. Cables are short but so are most load testers. She warms up good as they do but the coil handles it well. Would recommend. GOOD VALUE HERE

I've seen these around for years and when a shop would check my car battery, they would use one almost exactly like this model. I figured, if it was good enough to be used by a repair shop, it would be good enough for me. Worked flawlessly and as advertised. Clamped the leads to the battery posts, flicked the switch and it indicated that the battery had to be replaced on my sump pump battery backup system. Saved me a lot of time not having to check the Wayne backup system components. Now I have to get another battery and I'm good to go. It's a tool that you may rarely use, but if you have one, it pays for itself in allowing you to diagnose your battery and charging system without going to a shop or risking getting stuck in the middle of nowhere with a dead battery. Just be careful, follow instructions and always wear safety goggles when working around any lead/acid batteries.
