Universal Digital Battery Tester with LCD Display

Quickly Check Battery Power with Clear Digital Accuracy

The Universal Digital Battery Tester provides a fast, accurate way to check the remaining power in your everyday batteries. Featuring a clear LCD bar graph display, it allows you to see battery status at a glance, so you can immediately tell whether a battery is good, low, or needs to be replaced or recharged.

Designed for versatility, this tester supports a wide range of common battery types, including C, AA, AAA, D, N, 9V (6F22), and 1.5V button cell batteries. It is suitable for carbon, zinc, alkaline, and rechargeable batteries, making it a practical tool for both home and office use. Compact and lightweight (approx. 2.48 x 0.55 x 3.62 inches), it fits easily in a toolbox, desk drawer, or gadget bag. The unit operates within a working temperature range of 0°C to 40°C and is powered by an included 1.55V button-type battery, so it is ready to use out of the box.

Use the tester to quickly verify batteries from remote controls, toys, flashlights, wireless accessories, and more. By checking batteries before disposal, you can reduce waste and avoid discarding cells that still have usable charge. This simple diagnostic step helps prevent misdiagnosing devices as faulty when they only require a fresh battery.
