Review on Maximize Vehicle Performance with Performance Tool W1657C Deluxe Battery Tester, Black by Harry Katab

Waste of money. Spend a little more and get a decent product. I bought this about 3 months ago to help me troubleshoot my electric golf cart batteries. When I first used it with some effort, I was able to collect enough fluid and get measurements that helped me identify the faulty cell. My first impression was that you get what you pay for so I was satisfied. After changing the battery and then using it for some time I decided to check all 6 batteries (in my 48 volt wagon) and found that the bulb was too weak to get enough fluid all the time. , and the measurements are inconsistent. I needed it again today to fix my son's car and now it says all cells are bad even after a full 12v charge. Doubting it, I checked my truck's battery, which works fine. and you guessed it, same results. It's going to the dump!
