Review on OEMTOOLS 24338 100A Battery Tester by Telly Roden

This device is so easy to use that I can't believe I waited so long to receive it. Sure, he's trying to add a little more to the meter scale, but it's pretty clear what the point is. The only weakness I found was that it doesn't work very well with smaller batteries like lawn mowers. Even if they are brand new, they show up as marginal. It is very difficult for these small batteries to deliver the promised 280 amp hours - 200 amp hours is the limit and hardly shows up on the meter. This tester works very well with all types of car batteries at 12VDC. and higher, but at a lower voltage, e.g. B. 6 V DC, the performance is worse. one leaves when it has no chance of serving properly and will soon fail. This tester is worth every penny spent.
