Zinc Air battery type 13
This environmentally friendly type of battery has
about twice the lifetime of a mercury battery when
treated correctly. It can be stored up to two years,
as long as the sealing label is not removed. There-
fore, do not remove the label until just before in-
serting the battery in the instrument.
Once inserted, the battery will start functioning
after a few seconds.
Operate your hearing aid with the same battery
until it is exhausted (see p. 9).
On occasions, a new battery may be exhausted be-
cause it was not sealed properly. If your hearing
aid does not work after you have replaced the bat-
tery, try inserting a different new battery.
