Review on TOPDON BT200 Car Battery Tester: Accurate 24V 12V Load & Alternator Testing for 🚗 Automotive Vehicles - Digital Auto Battery Analyzer for Car Truck Motorcycle ATV SUV Boat Yacht by Jeff Kersey

I think this is a good product that gives accurate readings. I also have a Midtronics PBT-300 and the conductivity readings are very close. I like the fact that it gives internal resistance values. Also appreciate the battery, alternator and starter test functions, the fact that it tests both 12V and 24V batteries and is compatible with regular flooded / VRLA / GEL / AGM / EFB batteries is. For the DIY enthusiast, this is a good tester to detect battery problems early and before charging the generator. It is important to ensure that the clamps make good contact, otherwise you will get erroneous results. If you get weird readings or really bad numbers, move the clamp connections and test again. The Car Care Nut on YouTube (Toyota Master Mechanic) has a great review of this tester.
