Acousticon No. 2-R Hearing Aid Battery
The Acousticon No. 2-R, 3 volt battery was used in
some carbon hearing aids from around 1910 through to the 1930s.
It weighed 6½ oz., and measured 2"
by 1" by 3½" high.
In the Acousticon Battery price list of June 1, 1935 it is listed as
selling for $0.45 each.

The top view of the Acousticon No. 2-R battery showing the battery
contacts—actually threaded nuts so you could screw in the contact posts
for the hearing aid you were using. The left side shows a post screwed
in, while right side shows the battery terminal itself. Incidentally, the two terminals have different sized holes so you
couldn't accidentally hook the battery up the wrong way. The right
contact is the larger size.

This newer version of the Acousticon 2R battery has straight push-in
sockets rather than screw sockets like the battery above. Again, the
right socket is the larger size. |

Rear view of another Acousticon 2-R battery showing advertising for a
newer hearing aid. As is true today, the ad is long on hype and short on
details. This ad reads:
