| All batteries
are toxic and dangerous if swallowed. Keep all
batteries (and hearing aids) away from children
and pets. If anyone swallows a battery it is a
medical emergency and the individual needs to
see a physician immediately. |

One question
often asked is "How long does the battery last?"
Typically they last 7-14 days based on a 16 hour
per day use cycle. Batteries are very
inexpensive, costing less than a dollar each.
Generally, the smaller the battery size, the
shorter the battery life. The sizes of hearing
aid batteries are listed below along with their
standard number and color codes.
- Size 5 RED
- Size 10 (or 230) YELLOW
- Size 13 ORANGE
- Size 312 BROWN
- Size 675 BLUE

| Today's hearing
aid batteries are "zinc-air." Because the
batteries are air-activated, a factory-sealed
sticker keeps them "inactive" until you remove
the sticker. Once the sticker is removed from
the back of the battery, oxygen in the air
contacts the zinc within the battery, and the
battery is "turned-on". Placing the sticker back
on the battery will not prolong its life. Since
many of today's automatic hearing aids do no
have "off" switches, removing the battery at
night assures that the device is turned off.
Zinc-air batteries have a "shelf life" of up to
three years when stored in a cool, dry
environment. Storing zinc-air hearing aids in
the refrigerator has no beneficial effect on
their shelf life, in fact, quite the opposite
may happen. The cold air may actually form
little water particles under the sticker. Water
is made of oxygen and hydrogen. If the water
vapor creeps under the sticker, the oxygen may
contact the zinc, and the battery could be
totally discharged by the time you peel off the
sticker! Therefore, the best place to store
batteries is in a cool dry place, like the back
of your sock drawer, not the fridge! |
