The Miracle Ear ME9Z zinc-air hearing aid battery is really a No. 675

by Dahlberg, Inc. of Golden Valley, MN. These batteries probably date
from the 1990s.
The ME9Z 1.4 volt batteries had a capacity of 520 mAh.
These zinc-air batteries were the same size as other No. 675 batteries
and weighed around 0.09 oz.
and measured 0.455" in diameter

Bottom view of the Miracle Ear ME9Z zinc-air battery showing the
positive (+) terminal. Note the three holes in the bottom. These holes
let air into the battery to activate it. That is why it is called a
zinc-air battery.
Once the blue tab (below) is removed the battery starts working (and
thus running down) whether you use it or not. |

blue tab covering and sealing the 3 air holes so the battery is not
activated and thus has a long shelf life. The blue tab is the
standard color for all 675-sized zinc-air batteries, no matter who makes
them.
