Zenith Type "N" Phantom-Dummy Hearing Aid Battery
This phantom-dummy type "N" battery eliminator was probably made for
the Zenith Radio Corp. for use in a couple of their higher-powered
hearing aids that could use either one or two batteries, depending on
the desired power output. Two likely candidates were their Regent (1955)
and Royal Regent (1964) transistor hearing aids.
This phantom-dummy battery eliminator was the standard type "N" size
and weighed 0.1 oz. (5 g).

Top view of the ?Zenith phantom-dummy type "N" battery eliminator
showing the positive terminal. Basically all it consists of is a metal
rod in the center surrounded by plastic.
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.

showing the positive terminal sticking out (right). There are no
identifying marks on this battery eliminator, so I cannot be sure it was
for Zenith hearing aids. However, since it came with some Zenith hearing
aids and parts, I think it was for use in Zenith Regent & Royal Regent
hearing aids.
