Why choose zinc-air technology for hearing aid batteries? Zinc-air hearing aid batteries have a particularly high energy density and provide an almost flat discharge curve. Therefore, they are the optimal power supply, especially for hearing aids. The air holes of the battery are initially covered with a protective film, keeping it in a "standby" state until it is needed. The self-discharge rate of zinc-air batteries with the protective film applied is only about 3% per year. The film is removed when inserting the battery into the hearing aid. After a few seconds of activation time, the battery begins to discharge. In the activated state (with the protective film removed), zinc-air batteries have a limited shelf life and should be used as soon as possible.
