The ZA675 is a
popular battery for behind-the-ear hearing aids. All manufacturers colour code
this battery blue for easy identification. However this should not be confused
with the high power ZA675P cochlear implant batteries that are also colour coded
blue.
What makes the Zinc Air battery unique is that it uses oxygen from
the atmosphere. It has a small hole in the case that allows air into the
battery, which is used as part of the chemical reaction. The battery is not
activated until the plastic seal is removed. Typical applications are hearing
aids, pagers and personal medical instruments.
