A hearing aid is an electroacoustic apparatus that typically fits in the ear (ITE) or behind the wearer's ear (BTE). The apparatus is designed to amplify and modulate sounds for the wearer. A hearing aid primarily has three main parts, the microphone to receive sounds from the surroundings, and the amplifier to amplify and modulate the sounds, and the receiver or speaker to reproduce the amplified sound. The device's electronic circuits are powered by a battery. Currently, the batteries for hearing aids are mostly disposable. Non-disposable batteries are usually permanently sealed within the hearing aid shell. A novel solution introduces a concept of replaceable, rechargeable battery cartridges using mobile devices with internal power source that applies to both custom hearing aids and BTEs (see Figure 1). The mobile battery charger contains internal, high capacity power source. The charger's internal power source can be either a rechargeable or a disposable battery. The mobile battery charger contains multiple ports for batteries or battery cartridges with batteries enclosed within standard housing for easy replacing. Charging of each battery/cartridge is controlled separately.
