The Power-One zinc air hearing aid batteries contain no mercury.
The world's largest and most modern hearing aid battery plant is located in Ellwangen, Germany, where the Power-One MERCURY-FREE battery cells are created.

They provide eco–friendly battery technology, produced under clean room conditions, with an Enhanced Safety & Performance housing coating.

Power-One MERCURY–FREE battery cells are manufactured using only high–grade and refined raw materials. Their energy management system is certified in accordance with ISO 50001. With the new international standard, energy consumption and energy policy are placed center stage.

Power-One MERCURY–FREE means, for you, hearing aid energy with premium performance and durability – of course with the patented stable high level of voltage that power one provides.



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