Just How Long Should My Hearing Aid Batteries Last?
Even though the battery performance for hearing aids might sound like a
straightforward question to answer, in truth it depends on a variety of
factors. One factor is the manufacturer of the hearing aid. Battery
performance differs by manufacturer and also by model from the same
company. The actual life of a hearing aid battery also depends upon the
amount of time each day that the hearing aid is on. As you would expect,
the more you use your hearing aid, the faster the batteries will be used
up.
There are even varying battery
lives in the same size of hearing
aid battery depending on the
manufacturer, and depending on if
you are purchasing that
manufacturer’s “premium” line or
their “normal” line of batteries.
Hearing aid battery life also
depends on battery type; for
example some varieties are only
discharging power when they are
inside a hearing aid that is on, and other varieties (such as, zinc-air
batteries) start burning stored energy as soon as you remove the
adhesive strip on the bottom of the battery and they’re in contact with
oxygen, regardless of whether the hearing aid is on or not.
If you are looking for a new hearing aid, you might wish to do some
research first to see which have the best ratings for battery life, because
that could influence your choice of which type or which model of hearing
aid to purchase. The same research suggestion holds true if you have an
existing hearing aid and are looking for the batteries with the longest life

for it; you can uncover a great deal from consumer ratings and
comparative reports.
Thankfully, when shopping for hearing aid batteries, their manufacturers
have made things a little easier for you by standardizing their sizes and
color-coding each size; the identical color codes are used by all
manufacturers. The hours listed below for each size are approximations,
but can give you a basic idea of how long batteries of each size ought to
last given normal use:
• Yellow – #10 about 80 hours
• Orange – #13 about 240 hours
• Brown – #312 about 175 hours
• Blue – #675 about 300 hours
To ensure the longest life for your batteries when they’re in the hearing
aid, turn the hearing aid off when you’re not wearing it. To ensure the
longest shelf life for hearing aid batteries you have purchased but haven’t
used yet, store them indoors, at room temperature, and in their original,
unopened packaging.
