More info

With this handy Rayovac battery tester, you're never surprised. Is it now the battery or the hearing aid? This tester gives you quick security. Because of the convenient storage compartment, you can always make sure you have 2 spare batteries.

Some key features of this tester are:
Performed as a keychain.
For all 1.4 Volt batteries.
Suitable for all sizes & types of zinc-air hearing aid batteries.
The Rayovac battery tester has a digital display.
Small storage compartment for 2 spare batteries.
Very easy operation.

The operation is quite simple:

  • You place the battery on the front face.
  • Slide the battery against the bracket for making contact.
  • The tester shows how much energy the battery contains.

Note!: NOT suitable for rechargeable batteries.
Hearing Aid batteries are usually of the type of zinc / air and as soon as you remove the stick, air is in the air and that reacts with the zinc. This means that if you remove the sticker you basically use the battery and the quality becomes less, stickback backing will not help. So do not remove the sticks until you use the batteries.
