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.

They arrived quickly and work well. I like that they don't have a battery to replace.

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!

Came exactly as described. Works well. Would recommend. Is smaller than i thought but i like it bc it takes up less space and you can take it places if you want. Very simple and easy to use and understand. Went through my pile and found some batteries that weren't dead that I thought were. Came with two.

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

Thought it was working well until I realized it was lying to me. It would tell me my rechargeable batteries were fully charged and then go to use them and they weren’t. Good thing there was 2 in the pack. Started using the second one and it worked for a minute…. (I think) and same thing. Digital maybe better???? 🤷🏻‍♀️

Simple easy to use requires no power source other than the battery to be tested. Is compact and works well.

These battery testers work well though they do appear a bit flimsy. Can’t beat the price!
