Inside the air connects to the contained zinc. Zinc oxide is formed. The result of the chemical reaction is therefore the energy required by your hearing aid in the form of electricity.
For protection, however, the holes of this battery are sealed ex works with a protective film until you get it delivered. As a result, the air can only penetrate when the energy is also to flow. As soon as you remove the slide and use your hearing aid, the power for the power supply runs. For you, however, this also means that the battery discharges from this point on.
