Abstract:
A device to transfer a tiny hearing aid battery to the battery compartment of a hearing aid. Pressure on a button at the top creates contact to a single AAA battery, thus energizing an electromagnet which then holds the hearing aid battery. When the pressure at the devices's top button is released, the AAA battery is turned off and the battery is released undisturbed in the hearing aid's battery compartment.
