In Truth, What is a Typical Life for Hearing Aid Batteries?

Hearing Loss BlogEven though it might seem to be a straightforward question to ask just how long hearing aid batteries are good for, it isn’t. How long hearing aid batteries will last is determined by quite a few variables. Battery life will depend on the model of your hearing aid, and may vary widely across models developed by the exact same manufacturer. The way you use your hearing aid will also affect battery life; the more hours each day yours is turned on, the more often you will use up batteries.

The batteries themselves are a key factor. Batteries the exact same size from different manufacturers will have different lives. And there will be variance within one battery manufacturer if they offer premium or extended-life lines. Some hearing aid batteries will not start to deplete their power resources unless they’re plugged into a hearing aid that is powered on, and some (such as zinc-air batteries) will begin to burn power the moment you pull off the adhesive tab on the bottom of the battery, and will continue to lose power even if the hearing aid is not turned on.

If you are looking for a new hearing aid, you might wish to do some research in advance to see which have the best ratings for battery life, because that may influence your decision about which type or which model of hearing aid to buy. If you have an existing hearing aid and are searching for the most long-lasting batteries for it, the Internet can be a great source of comparative ratings and reports.

Hearing aidand battery manufacturers have worked to make things simpler by standardizing their sizes and using unique color codes for each size which is the same for every manufacturer. The times listed below for each size are estimates, but can give you a basic idea of how long hearing aid batteries of each size should last given normal use:

  • #675 – Blue – 300 hours
  • #312 – Brown – 175 hours
  • #13 – Orange – 240 hours
  • #10 – Yellow – 80 hours

Don’t forget to turn your hearing aid off when you aren’t using it for the longest battery life. Store your unused hearing aid batteries at room temperature, indoors, and in their original, unopened packaging to ensure their longest possible life.
