Review on 🚗 Cutting-Edge Wireless Bluetooth Car Battery Tester for Android & iOS - Analyze, Diagnose, and Optimize Automotive Battery Performance of Regular Flooded Batteries, Auto Cranking and Charging Systems, Covering All 12V Vehicles & Boats by Chad Michels

I'm still playing with him and trying to decide if he can be trusted. On some batteries this gives me pretty plausible results, but on some I've gotten some weird readings, like a 200 CCA battery saying this thing is 900-1000+ CCA (see screenshots), either this some sort of super battery or . ? Another weird thing was that the lawnmower battery was dead for a long time, the tool sure tells me it's in bad shape BUT the test shows 9.5 volts when my voltmeter shows 11.06 which is a quite a discrepancy. So the jury is still out on the accuracy, I don't know. The app is ok, easy to use but a bit unreliable. The battery monitoring test crashes the app, so I can't seem to use that test. However, the app is much simpler than tapping the built-in small Gameboy screen like other models, and it's nice to be able to take screenshots of the results for reference. You can take a battery snapshot and then run a test, and then take a screenshot of the result. and later when I look at my photos everything is there. The device itself seems well made but it makes me laugh, they have this THICK insulation on tiny 24 gauge wires that lead to huge battery terminals/jaws, pretty weird but I think it looks in a tool box cool if not more. I'll keep playing with it and we'll see if it turns into something I trust for battery health.
