Batteries

January 28, 1946

Tiny dry battery that powered the “handie-talkie” used by Army Signal Corps has now been developed into the commercial model shown in the picture, used principally in hearing aids.

Chemical reaction of zinc and mercuric oxide operates the cell; conventional cells use zinc and carbon.
