Check Common Batteries Quickly and Easily

This universal battery tester is a simple way to check the condition of many popular household batteries. It works with AAA, AA, C, D, 9V, and button cell batteries, making it a useful battery checker for home, office, shop, and hobby use. Whether you are testing batteries from remotes, flashlights, toys, clocks, or small electronics, this tester gives you a quick visual reading without requiring any batteries of its own.

Easy-to-Read Analog Battery Tester

The built-in analog needle meter features a color-coded scale that is easy to understand at a glance. The green range indicates the battery is good, the yellow range indicates low power, and the red range shows the battery should be replaced. This makes it a practical battery tester for everyday users who want a fast answer without complicated controls or digital menus.

Works with Multiple Battery Types

This multi-size battery tester is designed to test standard 1.5V batteries, 9V batteries, and button cells. When testing 1.5V and 9V batteries, read the scale from the top. When testing button cell batteries, read the lower section of the scale. If the needle does not move, make sure the battery is touching both contacts properly before assuming it is fully dead.

Compact Handheld Design with Manual Sliding Contact

The tester features a sliding red contact that adjusts manually to help fit different battery sizes securely during testing. Its black plastic body is lightweight, durable, and easy to store in a drawer, toolbox, or workbench. Measuring approximately 4-1/2 inches by 2-1/2 inches, it is compact enough to keep close by whenever you need to test loose batteries.
