Dlyfull Universal Battery Tester with LCD Display, Multi Purpose Small Battery Checker for AA AAA C D 9V CR2032 CR123A CR2 CRV3 2CR5 CRP2 1.5V/3V Button Cell Batteries

Good quality and easy to use.

Perfect, does exactly as described. So handy.

It does the job .tests a wide selection of batteries . Build quality is a bit cheap.don’t know how long itll last. But for the money excellent

Very good. Easy to use, I sorted all post xmas batteries and it's saved me money.

My wife likes how easy it is to use. It is reasonably accurate as well.

I had loads of batteries of varying sizes and was convinced that they still had power left in them and needed a way to be sure rather than just chucking them away. I opted for this battery tester because it can test most battery sizes. When it arrived I was pleased to see that it was fairly sturdy and after looking it over I tried all of the old batteries and found that most had power still in them. Only a couple need binning. I had also mixed up some new batteries which after testing confirmed that they were still full. so saved throwing our perfectly good batteries. The only concern that I found was that some of the batteries showed more than half life but in reality performed poorly when reused. I was pleased to say that I did save about 10 2025/2032 coin batteries which I had no idea if they were still ok or not. In conclusion you could continue to just test in other items but I found this tested was good to test loads of batteries I had stored like many people do. Will I get the money paid for this back-probably not.

Works well

Battery tester works well a little bit flimsy to use but ok

This tester works great. I bought it to replace a different tester that I was using. This tester is so easy to use. And I like how it can test so many different size batteries.

I have a number of battery-operated devices and like to take the battery out when not used over a period of time (previous bad experiences with leaked battery juice). This device works on all my battery types and I can tell in an instant which battery is good even though they are all mixed up in my battery storage compartment.

Pretty cool! Especially at this low price. I had a bunch of AAA batteries, some dead, some not, that motivated my purchase. It made them easy to sort into Keep/Discard. Same for some AA. Haven't tested all other sizes yet, but based on AAA and AA I can say that the device's "fit" to the battery is not "perfectly snug", may require a little jiggling to be sure if one is dead, but it does work.

I like that all the batteries you can test on this tester are easy to use. Fast delivery. I like it sooooo much
