    Customers are mixed about the battery. Some mention that it does what they need it to, with an easy-to-read display that provides accurate readings of the battery life level. They say there is no battery required and it allows them to identify which batteries need to be tested. However, others say that the light flimsy plastic makes the batteries fall right out of it, and the battery tester stopped working within the first six months.

    These household battery testers are made cheaply and are inexpensive, but you can't beat the price,
    2 for under $6. They are packaged well and were received within 24 hours of ordering. The best part is, they work great! Easy and inexpensive way to check batteries that are lying around your house before tossing them out. They're worth a try.

    5.0 out of 5 stars great battery tester
    Reviewed in the United States on January 8, 2024

    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.

    This tests batteries well, and it doesn't require a battery like the last one I had. I had been searching for months for a battery to make the last one work, and I finally gave up and bought this one, which doesn't require a battery. I tossed the other battery tester. It's so nice to be able to get my battery sorted out finally!
