Hearing Aid Battery Life
Hearing aid batteries can last from 4-14 days, depending on the size of the battery, your hearing aid model, 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 that will be used.
You may be wondering why these batteries lose their power so quickly. Hearing aids perform complex functions to amplify the sound correctly to meet your needs and the varying listening environments you are in throughout the day. Watch batteries, on the other hand, may last years, but require little power to keep ticking.
Hearing Aid Battery Storage
The best place is right where you store your hearing aid at night, or when you take it out…in a bedside table or, if you have space, in a drawer in your bedroom. That way the batteries will be there when you put your hearing aids in first thing in the morning. Of course you may want to keep spares with you in your hearing aid carrying case, too.
And no, it’s not a good idea to keep batteries in the refrigerator. Condensation and moisture can harm them. Avoid extremes in temperature, too. Hearing aid batteries like room temperature—just like you.
