Wireless battery charging system for existing hearing aids using a dynamic battery and a charging processor unit

A method of converting a Prior Art hearing aid which uses disposable batteries into a rechargeable hearing aid, comprising the steps of:

• removing a non-rechargeable battery from a battery compartment of a Prior Art hearing aid,
• replacing the non-rechargeable battery in the Prior Art hearing aid with a rechargeable battery and inductive charging circuit comprising an inductive charging circuit formed within a first portion of a housing of a standard hearing aid battery cell and a rechargeable battery, formed within a second portion of a housing of a standard hearing aid battery cell,
• wherein the resulting converted hearing aid may be recharged by placing the hearing aid near an inductive charging station which induces a current into the inductive charging circuit formed in the combined rechargeable battery and inductive charging circuit so as to recharge the rechargeable battery.

A system for recharging small appliance batteries, comprising:

• in a removable battery case, a combined battery, inductive coil, and charging circuitry, contained within the battery case having the same dimensions and being interchangeable with, a standard non-rechargeable battery, for placement within a small appliance;
• and
• a charging unit, provided with an inductive coil, for generating an electromagnetic field such that when a small appliance with the combined battery, inductive coil, and charging circuitry installed is placed near the charging unit, a current is induced in the inductive coil of the combined battery, inductive coil, and charging circuitry, charging the battery.
