Hearing Aid Batteries

Vicon Type "N" Phantom-Dummy Hearing Aid Battery

This phantom-dummy type "N" battery eliminator was probably made by or for the Vicon Instrument Company for use in their higher-powered hearing aids that could use either one or two batteries, depending on the desired power output. This one came with the Vicon Model M-8 transistor body aid.

This phantom-dummy battery eliminator was the standard type "N" size and weighed 0.1 oz. (6 g).

Basically all it consists of is a piece of aluminum in the shape and size of a type "N" battery.

There are no identifying marks on this battery eliminator, so I cannot be sure it was for Vicon hearing aids. However, since it came with the Vicon model M-8 hearing aid, that is a good indication it was either made by or for Vicon.

The ?Vicon phantom-dummy type "N" battery eliminator (right) was exactly the same size and shape as a standard type "N" hearing aid battery so it could fill one battery slot.

The ?Vicon phantom-dummy type "N" battery eliminator shown filling the rear battery slot in the Vicon model M-8 hearing aid.

It's purpose was to fill one battery position so in low-power mode, the hearing aid would run on one 1.4 mercury battery.

In high-power mode, it was taken out and a second type "N" battery inserted in its place raising the voltage to 2.8 volts, thus increasing the power of the aid.

This is how it was used when this aid was set to low power.

This dummy battery was donated by James Cost, Folsom, CA. Thanks Jim!
