Review on ⚡ OTC 3180 Battery Load Tester: Reliable 100 Amp Testing Power by Rob Bishop

I've seen these for years and when the shop checked my car battery they used almost the exact same model. I figured if it's good enough for use in the workshop then it's good enough for me. Works perfectly and as advertised. I clipped the wires to the battery terminals, flipped the switch and it indicated the battery in my sump pump backup battery system needed replacing. I saved a lot of time by not having to check the components of the Wayne backup system. Now I just have to get a battery and I'm good to go. It's a tool that you might rarely use, but if you have it, it pays off by allowing you to diagnose your battery and charging system without having to visit a store or risk ending up with a dead battery in the middle stuck in nowhere Just be careful, follow the instructions and always wear safety goggles when handling lead-acid batteries.
