Review on 🚗 KONNWEI KW600 Car Battery Tester: Professional 12V Load Analyzer, Alternator Tester, and Voltage Test for Automotive Batteries by Ray Adair

I immediately liked this gauge. Easy to read, smooth firmware update from website, easy to use. So far I've tested my motorcycle battery, car batteries, and a few small toy car batteries. I think the readings are correct. I compared the voltage with a meter with the same results. I believe the cca readings are correct based only on the age and wattage of the batteries I tested. A lot can be seen from the function of a signal, especially at the start. I like the review and print program, but I don't think I'll ever use it. It would be good for a business or handyman to keep track of many devices like I did in a past life. Overall I think this is a very good buy and other reviews suggest there is good customer support and a 3 year warranty.
