performance, however hearing aid battery dimensions are
standardized within the industry. For instance, a size 312 hearing aid battery across manufacturers should fit in your

A zinc air battery uses air outside the battery as a source
of power. The factory applied tab seals the air holes in the
battery and ensures freshness until you are ready to use the
battery. Do not remove the tab until you are ready to use
the battery. To activate the battery, you simply remove the
tab. After removing the tab, wait about one minute prior to
inserting the battery into syour hearing aid. This allows
sufficient time for the air to enter and activate the
ingredients. Replacing the tab when the battery is not in
use will not extend the battery life.
