Very easy to use. Gives accurate results. Lightweight and easy to storeGood value for the money.

Very easy to use, small in size so easy for storage. I’ve needed one of these for a while! Wish I got this sooner!

I got this tester to replace an old tester that stopped working. While this tester works fine, I do have 2 design suggestions that would improve this tester that my old one had: 1) there was a “channel” that you would place a cylinder battery in that held the battery in place, and 2) the slide lever that made contact with the battery was spring loaded, which also made it easier to keep the battery in place while testing it. Without these two design features, with this battery tester you have to be sure that you have the battery properly held in place, which is why I gave this tester 4 stars instead of 5. That said, it does the job it’s supposed to.

works great!! just what i needed

Perfect! the price was great

I bought this little tester for my Mom who had a box full of various sizes of batteries of unknown status. We tested them all and found many that were still full power and some that were ready for the trash bin. This tester is:-- accurate;-- quick and easy to use;-- battery size and orientation markings are easy to read and understand by anyone;-- very budget friendly!

Not a quality product

Very accurate once I figured which end goes on top.
