The average hearing aid user wears their device for 8.6 hours per day, and most batteries last between 80 to 220 hours, depending on the hearing aid brand, how often you use streaming services, and your maintenance routine. While 220 hours may seem like an extremely long time, you’ll probably be changing the batteries every week or every other week.

However, make sure you change your hearing aid batteries before they die. Dead batteries tend to swell, which can easily damage a hearing aid.

Activate The Battery

After taking the battery out of the packaging, you’ll see a sticker label with a “+” sign on one end of the battery. Pull it off so that the battery is exposed to oxygen. Most hearing aids use what is known as a zinc-air battery. Zinc-air batteries require oxygen to function, so let it sit outside of its packaging for a few minutes before placing it into the hearing aid. Note that once you take the seal off the battery and expose it to air, the battery’s lifespan is ticking.

Remove The Old Battery

Your hearing aid should have a very small tab in the back. Push it open so that the old battery is exposed. Turn the hearing aid upside down, and the old battery should fall out. If not, there is a small hole above the battery drawer. You can use a needle-thin object to push the old battery out.

Insert The New Battery

Once you’ve removed the old battery, insert the new battery with the “+” sign facing upwards.

The door should close with ease. If it’s stuck, double-check that the battery is facing the correct direction. Never force the door shut. It should make some noise to indicate that the new battery is ready to go.

How Can I Make My Hearing Aids Last Longer?

While you will have to change your hearing aid batteries eventually, there are some tricks you can use to make them last longer.

Before you go to sleep, open the battery door to reduce moisture build-up and turn the hearing aid off.

Never store hearing aid batteries in your pockets or wallet where they could be exposed to keys, coins, or other metals. The metals can cause the zinc-air batteries to short circuit and die.

Like any batteries, avoid storing them in extreme cold or heat.

Dropping the batteries can also damage them, so be sure to always change them on a soft surface like a towel or rug.


Hearing aid batteries are becoming increasingly advanced, and new research shows that even zinc-air batteries may become rechargeable soon. In addition, the zinc-air batteries are more environmentally friendly than traditional batteries as they do not use organic electrolytes

In the meantime, always keep a few extra batteries on hand. With a little bit of practice, you’ll be changing your batteries in a matter of seconds.
