Your hearing care professionals — that’s us — will tell you which size and color of hearing aid batteries you need.

Hearing aid batteries typically last about 5 to 7 days, depending on the size of the battery, your model hearing aid, level of hearing loss and the demands of the location where you use them. The more active your hearing aid is, the more battery power it will use. If you purchase rechargeable hearing aids they can last up to 24 hours.

Wrist watch batteries can last years because it requires little power to keep your watch ticking. Hearing aids, on the other hand, require more power to perform complex functions that amplify sound correctly to meet your needs in varying listening environments. If you feel you are changing batteries too frequently, ask us about rechargeable hearing aid batteries.

It’s easy. Keep at least a month’s supply of hearing aid batteries on hand, about eight to 10, and stop in once you’re down to four since they are included at no charge with the purchase of your hearing aids at Duncan-Nulph Hearing Associates. Also consider trying rechargeable hearing aids.

The best place is right where you keep your hearing aid at night: in a bedside table drawer. That way, the batteries will be there when you put your hearing aids in first thing in the morning. It’s a good idea to keep spare batteries with you in your hearing aid carrying case, too.

Yes! There are a number of companies now making rechargeable hearing aids and hearing aid batteries. While they are a bit more expensive upfront, rechargeable batteries can free you from having to buy and dispose of replacement batteries.
