Why zinc-air technology for hearing aid batteries? Zinc-air hearing aid batteries have a particularly high energy density and offer an almost flat discharge curve. They are the optimal power source, especially for hearing aids.

The air holes of the battery are initially covered with a protective film to keep them in a "standby" state until 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 supply power. In the activated state (protective film removed), zinc-air batteries have a limited shelf life and should be used as soon as possible.

Wireless tested Rayovac Extra 13 hearing aid batteries. Wireless technology is now indispensable for hearing aids. Speech signals are transmitted to your hearing systems via hearing aid accessories. This data transmission requires a consistently high power supply. Rayovac Extra 13 hearing aid batteries provide the quality and stability necessary for uninterrupted transmission.
