BATTERIES (CONTINUED)
Zinc-Air Batteries
Hearing amplifiers use commonly-available #10
zinc-air hearing aid batteries. They are easy to
find in pharmacies, online and other retail
locations, including Radio Shack.
• Zinc-air batteries have a long shelf life, but once
the tab is removed, battery life is about 9 days
for continuous operation.
• Battery life is about 2 weeks if the devices are
turned off after each use.
• Once the tab is removed, zinc-air batteries may
self- discharge in about 4 weeks whether used
or not.
• The discharge rate varies with temperature and
humidity.
• It is sometimes possible to prolong the life of a
battery by replacing the tab over the air holes,
but results vary.
