Handling batteries
in hearing instruments to minimize environmental
damage. These batteries require oxygen for operation,
which they absorb 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 of time. The batteries can leak and damage the instruments.
