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.
