Activair Button Cell Hearing Aid Battery Tester
The Activair button cell hearing aid battery tester was produced by/for
Activair, one of the companies making zinc-air hearing aid batteries.
This tester was made in Korea, probably somewhere around 1980.
It was designed to test zinc-air hearing aid button batteries in
common use such as 675, 13, 312 and 10 batteries.

The Activair button cell hearing aid battery tester was quite large for
just testing button cells. It measured 3 5/16" x 1¾" x ⅞" (8.4 x
4.4 x 2.2 cm) and weighed 1.2 oz. (34 g).

Close up of the meter of the Activair button cell hearing aid battery
tester. This meter was easy to read. If the needle remained in the red,
the battery was bad and needed to be replaced. If the needle moved to
the green, the battery was good. |

Close-up of the bottom front of the Activair button cell hearing aid
battery tester showing a
slot where you placed the battery to be tested. The top of the battery
(- terminal) went to the left.
The slot was bigger than the largest zinc-air hearing aid battery,
the No. 675, so the battery would readily fall out after testing.

so in order to get contact with both terminals, you pushed a button on
the right side.

To Test" button pushes the positive plate about half way into the
battery slot before it makes contact with the tiny battery. You could
even test the miniscule No. 5 zinc-air battery, the smallest battery
made for hearing aids, but at this point, that battery had not yet been
made.
