Test all size hearing aid batteries

A portable, convenient way to carry your hearing aid battery tester!

This handy tester measures the remaining power of many common hearing aid button cell batteries. The unit is self-powered, drawing the energy it needs from the batteries tested. Simple insert a battery “+” up and gently push the battery against the metal bar under the words “Battery Tester”. The digital LCD screen displays a bar graph showing the remaining power for each battery tested.

And, as an added value, the Battery Tester has a slide-out battery compartment, which can hold 2 extra batteries, so you can always have a spare. And of course, the handy key chain link means you can keep the tester with you at all times, no matter where you go.
