Should I Refrigerate My Hearing Aid Batteries?

Hearing aid batteries: to refrigerate or not to refrigerate?


I have been asked that question for over 15 years. Long ago it helped to refrigerate batteries to get longer life. With today's zinc air battery, it actually harms the battery. The zinc air battery has holes in the top and if you put hearing aid batteries in the refrigerator, the holes will allow moisture into the battery. The moisture fills up the battery and then you'll have premature failure of the battery. If you want to preserve the life of a hearing aid battery, keep them out of the refrigerator.
