Hearing Aid Batteries

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.
