Handling batteries

So-called zinc-air batteries are used today almost exclusively

in hearing instruments to mini- mize environmental damage.

These batteries require oxygen for operation, which they ab-

sorb from the air. The battery is activated as soon as the

protective foil is pulled off and is used up even if you do not use your hearing instrument.

You should always pull off the protective foil only if you actually use the battery. Also, do not leave the batteries in your hearing instruments if you do not use them over a longer period. The batteries can leak and damage the instruments. The batteries keep for from a few days up to several weeks according to the way they are used. You can recognize when a change of batteries becomes necessary, because your hearing instru-ments become noticeably quieter towards the end of the battery’s life. Then it is time for new batteries. Two warning tones sound once per minute, indicating that you must insert a new battery.

Your hearing instrument specialist can switch off the warning tones if required.

Zinc-air batteries which are almost completely used up show the following behaviour: After switching on the instruments they function completely normally, but then rapidly become quieter. The more the battery is used up, the faster the gain falls off. You must then replace such batteries by new ones.
