A battery assembly is constructed of an elongated plastic shell irregularly shaped to fit optimally in anatomical cavities, particularly ear canals. The battery assembly relies structurally on a thin plastic shell which is designed to be inexpensively formed in a variety of complex shapes, thus offering superior volumetric utilization and energy capacity when compared with conventional metal button cell designs. In preferred embodiments, the shell is domed to distribute axial stresses so that it can be thin and still provide sufficient strength to avoid breakage in an extended wear environment despite its plastic composition. A preferred embodiment of a hearing device incorporating the battery assembly is disposable, to be discarded upon depletion of the electrical energy of the battery assembly.

Miniature plastic battery assembly for canal hearing devices

A miniature battery assembly for canal hearing devices is constructed of a cylindrically elongated metal shell having oval cross section. The elongated oval design offers superior volumetric utilization and energy capacity in the ear canal when compared with conventional button cell designs. In a preferred embodiment, the battery assembly is comprised of an elongated anode can with an inward bottom ledge holding a cathode cup. The anode can is tapered on the top and oval in cross section for fitting optimally in the bony part of the ear canal. The hearing device incorporating the battery assembly is disposable to be discarded upon depletion of the electrical energy of the battery assembly.
