Zenith No. Z Hearing Aid "A" Battery
The Zenith No. Z 1˝ volt hearing aid "A" battery was made by the
Zenith Radio Corporation of Chicago, IL for use in their
Regent hearing
aid that came out in 1952.
The Zenith No. Z battery weighed 0.5 oz. (16 g), and measured 1
15/16" high
by ⅝"
in diameter (5.0 x 1.6 cm).
It was the same length as an AA battery but had a greater diameter
(and capacity) and thus lasted longer than AA-sized batteries.
