PowerOne is a well known brand name in the hearing aid battery market.
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.
