The Battery Organizer TBO30343 Tester Universal Checker for AA AAA C D 9V 1.5V Button Cell Batteries

I put batteries in holiday decor and they are in there for maybe a month or more. Some are on timers and are not used that much. I have a battery drawer and have all different size batteries in there. I recently changed the batteries ( 8 of them ) in my label maker. I pulled out the used batteries, hoping some still had some power. It still wouldn't work. I ordered this product and checked the batteries and one of the 8 was totally dead. At least I didn't have to pitch out all 8 of the batteries. I am so happy with this product and its so easy to use.

Love this tester!i needed a new battery tester because my current one is at least 13 years old, it seemed to be inaccurate and does not test the smallest batteries used in watches and the lazer we use for our cats to chase the dot it makes on the floor. So I went to Amazon to find one. There I found many different ones and even the same one I currently have and not wanting the same type I chose the TBO battery tester. I ordered it and received it very promptly and tested the batteries in my tv controller that my old tester registered as good but the controller was acting up. Using the TBO battery tester it registered the batteries as poor. I put in new batteries and the controller worked much more efficiently. I am very happy with the TBO tester and recommend others to buy one also

I have an old battery tester that showed the strength of the battery by either a green, yellow, or red light, but it didn't seem very accurate. This battery tester has a needle to indicate the actual strength of the battery. I can also check button batteries. It is a good battery tester,.

You need to have very steady hands and good placement positioning. Not good for an older person with arthritis. Can’t hold battery in place. Accuracy when input correctly is good, but too difficult to manipulate.

Fantastic product! Easy to use. We have a drawer filled with excess batteries that we are not sure whether they work or not. Anyone that has young children knows how frustrating it can be to change a battery for a toy only to have the child come back to you two minutes later saying that its not working again. The battery tester is saving us money as well as saving our sanity!

This works well and is very reasonably priced. It will test a wide range of batteries, but some of them have to be carefully placed in or on the device to get a good reading. I recommend the device for anyone who uses batteries--and that is almost everyone.

The device is easy to use and very accurate for the price of the device.

This tester is O.K., but it won't allow you to check D batteries. I use some of those at Christmas-time and that was one reason I purchased it. It's not worth the effort to try to return, but I'm a little disappointed.

Ideal para no desperdiciar las baterías. Siempre tenemos la duda de cuánta batería le queda y este producto es idea para eso y super fácil de usar.

No funciona. Muy mala calidad.

Fácil de usar y cumple su función
