A few years ago, the hearing
aid battery industry standardized battery
sizes and came up with a color code to help
you remember your battery size.
On the back of each battery is a tab that
you pull off to "activate" the battery. Each
color corresponds to a different size. Now
the numbers and colors for each size are all
standard. Sometimes you may see other
letters after the numbers, but those are
arbitrary letters. The most important thing
to remember is size and color as noted in
the table below.
If you can't remember your size, keep the
color in mind. Your (hearing healthcare
professional) will also have this
information in your chart and can look it up
for you any time.
