ABSTRACT:
This invention deals with a multipurpose hearing aid maintenance device. Its brush is used to clean a hearing aid, especially the receiver tube opening. The magnetized electrical terminal or an optional magnetic tip serves to hold small (size 13 or smaller) batteries to place them in a heating aid battery compartment or remove them from the compartment. Also, the magnetized electrical terminal holds the cell and serves as one of the two electrical terminals to test (GO/NO GO) electrical charge of the cells. Finally, the device can store one or two spare batteries.
