Product Information

The Sony brand is a well recognized leader in electronics, computing, and photo equipment. But did you know that Sony is also one of the largest micro battery manufacturers in the world.

Designed and developed specifically for hearing aids, Sony zinc air batteries will power up your hearing aid with long lasting performance and reliability you can count on.

All Sony button cells are made to Japan battery specifications. The superb performance of these hearing aid batteries will pleasantly surprise you.


Why zinc air technology?

Zinc air batteries have an especially high energy density and exhibit an almost flat drain curve. They are therefore the ideal power supply, especially for today’s digital hearing aids.

The air holes of the battery are initially sealed with a protective tab. They are kept in this way, in an “inactive state”, until they are needed. The inherent self-drain of zinc air batteries with protective tab attached amounts to a mere 3% a year. The film is removed when the battery is inserted into the hearing aid. After several seconds of activation time, the battery begins to produce current.

In the activated state (with protective tab removed), zinc air batteries can only be stored for a limited period and should be used as quickly as possible.

After removing the tab, please wait for 5 minutes so that the battery can fully activate and function at peak performance.
