a.
An individual’s
hearing loss
As severity increases, increased amplification
is required. This increases battery current, and therefore reduces battery
life.
b.
Sound
Environment
The noise around you can affect battery life.
A battery will drain less in a library as compared to a restaurant or rock
concert. Also, if the volume is “maxed out” on your hearing aid this will
prematurely drain the battery.
c.
Personal hearing
aid usage
Two things to take into account:
How many hours a day do they wear their hearing aid?
How many hours a day do they wear their hearing aid?
How many days a week do they wear their
hearing aid?
d.
Device
differences
The more advanced the hearing aid is, the
more power is required. Features in today’s digital instruments like wireless
streaming, Bluetooth connection and noise cancellation all require high current
to function. Below you can see how the current demands on the hearing aid
batteries change as the more advanced features are used.
e.
The
Natural Environment
Dryness As humidity is reduced,
batteries may dry out, reducing the battery life.
Temperature As
temperature is reduced, hearing aid battery voltage is lowered, which reduces
battery life.
High Humidity As
humidity increases, batteries may take on moisture, interfering with the
natural discharge expansion.
Altitude As altitude increases,
the percentage of oxygen in the air is reduced. This can cause the battery to
reach the endpoint earlier.
