2 Pack Battery Tester, Universal Battery Checker for AA/AAA/C/D / 9V / 1.5V Button Cell Batteries Household Battery Life Level Testers Power Monitor Meter (Requires No Battery for Operation)

These little guys work great! They are super compact so don't take up much room in your junk drawer. Super easy to use and have a straight forward guage so they are super easy to read and you know right away what the battery your testing is putting out. They work off the juice of the battery so in my opinion they are really accurate. Both units show the same levels when testing side by side. Really cheap but do exactly what you need from a tester.

I recently purchased the 2 Pack Battery Tester, and it has become an indispensable tool in my household. This universal battery checker is a game-changer when it comes to managing the plethora of batteries we use daily.The convenience of having a single device to test AA, AAA, C, D, 9V, and 1.5V button cell batteries is fantastic. No more guessing or searching for specific testers – this one does it all. The clear and easy-to-read display provides accurate readings of the battery life level, allowing me to identify which batteries need replacement.What sets this battery tester apart is the fact that it requires no additional batteries for operation. This not only saves money on constantly buying replacement batteries for the tester itself but also ensures that you'll never be caught in a situation where your tester is out of power when you need it the most.The compact design and the inclusion of two testers in the pack make it convenient for home use and also for keeping one in the car or taking it on trips. It's a simple yet effective tool that brings peace of mind, knowing that I can quickly check the status of any battery in my household without any hassle.If you want a reliable and hassle-free way to monitor your battery life levels, the 2 Pack Battery Tester is a must-have. It's a small investment that pays off in convenience and efficiency, making it easier than ever to keep your devices powered up.

These simple battery testers work well for AA, AAA, 9V, and button cells. The analog needle is easy to read and gives a quick good/bad indication. No power needed, just press and check. Great value for a 2-pack!

Simple device that works as intended. Awesome if you use rechargeable batteries in your devices.

I love these things. I was happy to get two, keeping one in my camper and one in the house. They are accurate. As an example, I had a device that used four (4) AAA batteries and the device wasn't working. I thought I would replace all of them but remembered I had this tester. I pulled the batteries out and started checking. Only one (1) of the four (4) was bad and the other three (3) tested as fully charged. I then only replace the bad one and the device has been working for over a week now. No problems and no batteries wasted.

The media could not be loaded. The packaging was ok but the build quality is very cheap. You can see the poor components open eye. It is easy to use and gives some good usability. I have tested my battery and it works normal. As a battery tester, it is a ok product. But the build quality is super poor and open for vulnerability.

Good price little hard to use but works great. Use it all the time I find batteries laying around can figure out whether they’re good or bad quick

Great value for a simple, reliable battery tester.
