Battery Tester for Cylindrical and Button Cells

The JJC magnetic battery tester checks voltage levels of 1.5V, 3V and 3.7V across a wide range of cylindrical and button cell chemistries. It supports AA, AAA, 18650, 14500, 16340, 10440, 20700, 26650, RCR123A, C, D, CR2 and CR123 types. Button cells covered include LR44, LR41, LR43, A76, CR2032, CR2025, CR1632, CR1616, CR2450, CR1225 and CR1/3N. A single press of the corresponding voltage button gives an immediate good, weak or poor indication.

Magnetic Contact and Voltage Selection

Strong magnets hold each cell firmly against the contacts while you slide the selector to 1.5V, 3V or 3.7V. Proper alignment of positive and negative terminals is required before pressing the test button. The tester must not be used with two or more batteries stacked together.

Pocket-Sized Health Check

The lightweight unit fits in a pocket or attaches to a keychain for on-the-go checks. It comfortably handles the listed cylindrical and button cell formats but cannot test 23A, 9V or larger pack batteries. Users needing to verify high-capacity packs or proprietary camera batteries will need a different instrument.

Questions about this item

What does the 1.5V 3V 3.7V range tell me about a battery once it is in the tester?

The tester shows whether the battery reads poor, weak or good by lighting bars after you press the button for the matching voltage index.

How does the magnetic contact interface limit what I can test?

You must align each battery's terminals with the magnetic port and test only one cell at a time; stacking cells is not allowed.

What physical space does the tester need to fit or mount?

It is small and light enough to carry in a pocket and the magnetic body lets it attach to a keychain for storage.
