Unknown 2 Carbon Hearing Aid
This unknown make of carbon hearing aid was made around 1930,
probably by, or for, a British company as it came from the United
Kingdom.
The overall height of this hearing aid was 7⅛". The battery
compartment itself measured 3¾" x 2⅝" x 1". The whole hearing
aid (without the battery) weighed 7½ oz.

This hearing aid took a 4.5 volt battery that had flat brass springs
on the top to engage the corresponding brass springs in the top of the
battery compartment. This was common with British-made carbon hearing
aids of this era. The
Ardente
Hearing Aid Battery shows these springs. This battery fits this
hearing aid.
