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.
Claims3
A tool for removing and installing batteries in electronic devices comprising:
- A cylindrical housing having a fore-and aft-end, and also having conduction means along said housing connecting a first point at the aft-end, and also having conduction means along said housing connecting a first point at the aft-end of the housing to a second point midway along the interior of said housing.
- A steel core mounted lengthwise inside said housing and protruding from said housing's fore-end by a predetermined length.
- An insulated wire coil wrapped around said core, bonded on one end to said second point midway along the interior of said housing and bonded on the other end to the core near the fore-end of the housing
- A power-source housed inside the aft portion of said housing, having a positive terminal and a negative terminal proximately disposed near the aft end of the housing.
- An activation means disposed at the aft-end of said housing, said activation means connecting the negative terminal of said power source to the first point of said conducting means when in the “on” position.
