2.3.1 Note on the battery
A zinc air battery is used to supply the power for your hearing
aids. This type of battery is only activated when oxygen comes
through the air holes into the button cell and the chemical
reaction is started. During production, the air holes are sealed
with a protective strip. This means that the battery remains
fresh until use, and it lasts longer when it is sealed. Removing
the protective strip allows oxygen to enter and the chemical
reaction is activated.
2.3.2 Low battery warning
An audible signal indicates the end of the battery life (approx.
30 minutes before the end of the battery’s life).
Important notes:
Refitting the strip when the battery is not
in use will not extend its service life.
Your batteries should be stored at room temperature. Avoid
keeping them in hot places or rooms with high humidity
(e.g. bathroom). Storage in a cooled location is not neces-
sary.
Never carry batteries loose in a trouser pocket or a purse.
Metal objects like coins or keys could cause batteries to
short-circuit.
Old batteries may contain hazardous substances or heavy
metals that pollute the environment and harm health. Bat-
teries are recycled as they contain valuable raw materials
such as iron, zinc, manganese or nickel. Old batteries should
not be placed in household waste. Consumers are bound
to dispose of batteries at a collection point provided by the
local authority or sales outlet. After use you can also return
the batteries in the appropriate containers at the premises
of your hearing care professional for free.
