Magnetic Battery Tester for Household Cells

This compact voltmeter checks AAA, AA, C, D, 9V and button cells using an internal power source. The magnetic tip secures each battery for a stable contact and accurate analog reading. It suits anyone who wants a quick, tool-free way to sort good cells from dead ones around the home.

Verify Battery Types and Sizes Before Use

Confirm the cells you test match the supported formats listed above. The device requires no external power, so no cables or chargers are needed. Ensure you have a flat surface to place the tester while the magnetic tip holds the battery in position for the measurement.

Replaces Guesswork and Disposable Testers

Unlike shaking a device or using a tongue test, this tool gives an immediate analog indication of remaining charge. The jump is worth it when you regularly discard batteries that might still have life, saving the cost of replacements over time.
