Proper battery handling and maintenance
Individual zinc air cells are stored with an adhesive
tab. The factory seal must not be peeled off until the
battery is required for use.
The tab seals the air hole on the battery. Once the tab is
removed, it takes approximately 30 seconds before the
battery is activated. Wait until the battery is ready.
If you do not use the hearing
instrument for a week or longer,
remove the battery and put the tab
back on its plus (+) end. Place the
battery with the plus (+) sign facing
down and store the battery in an
area that sustains approximately
60 percent moisture. If you fail to
do this, the battery will deteriorate
quickly and will be completely
exhausted in about a month.
If the battery is running low, the hearing instrument will
make an alert or warning chime.
If the battery has not been used for a long period of time,
it may swell. A weak or dead battery can severely affect
the functioning of your hearing instrument. Replace it
with a new one immediately.
The amount of battery life varies depending on the type
and amplification of your hearing instruments and the
number of hours of use.
Moisture accumulation in the hearing instrument causes
not to function correctly. Wipe clean with a dry cloth.
With or without an adhesive tab, do not stack more than
three batteries on top of each other or let them come in
contact with each other.
