Battery Tester

We're all guilty of hanging on to old batteries we're not sure about. Simple and dependable to use, this tester eliminates the guesswork, so you can finally see which ones are really worth keeping.

It works with any 1.2V to 9V battery, including rechargeables and most button-cells, giving an instant voltage reading you can compare to a chart on the side of the tester. Because it's powered only by the battery being checked, it always works – even a blank screen tells you right away that the battery is fit to be discarded.

Highly recommended.
