Review on Amprobe 4589825 BAT 250 Battery Tester by Sean Pierre

Two major problems with this tester: (1) Design. You insert the battery between two contact points on the side of the device, one of which slides to accommodate a different size battery. Holding the device and battery, manipulating the slider to make good contact, and reading the result is more of a challenge than it looks. It is very easy to drop the battery in this case. The only good way around this is to lay the device on its side and put the battery on top of the device, but even that balances it out a bit and also makes the result hard to read. (2) It is unreliable. It worked fine at first, but after a few months it became apparent that the new branded batteries to the right of the box were weak. I was going to return the batteries until I thought to check with another tester. You were fine. This device was wrong. Then I checked this device again and suddenly it now showed that the batteries were fully charged. It still sometimes shows that the battery is low, and sometimes it shows that the very same battery is strong. I'm definitely not doing anything wrong or anything. The device itself is simply unreliable, no matter how incomprehensible it may seem. He cannot be trusted, which of course makes him completely useless.
