Ear Center: Hearing Aid Battery Troubleshooting

Having trouble with your new hearing aid batteries?

Your new batteries are not dead. They just need to be "activated"!

Modern hearing aid batteries are a type of battery called a "zinc-air" battery and are non-rechargeable. Zinc-air batteries replaced mercury containing batteries that were prevalent in the 1970-1980's.

Zinc-air batteries are activated and powered by air. They must be "activated" before using them in your hearing aid or BAHA/Ponto sound processor. To charge your zinc-air batteries, you must:

  • Remove the sticker from the surface of the battery
  • Blow into the hole in the battery or shake the battery several times in the air
  • Wait 2 minutes before inserting the new battery into your hearing aid or BAHA/Ponto sound processor

Zinc-air batteries are not used to power cochlear implant sound processors. Cochlear implants use rechargeable batteries. Common rechargeable batteries are lead–acidnickel cadmium (NiCd), nickel metal hydride (NiMH), lithium ion (Li-ion), and lithium ion polymer (Li-ion polymer), not "zinc-air" batteries.
