Even though it may seem to be a simple question to ask how long hearing aid batteries will last, it isn’t. How long hearing aid batteries will last depends upon a large number of variables. One variable is the manufacturer of the hearing aid. Battery life varies by manufacturer and also by model from the same manufacturer. How you use your hearing aid will also impact battery life; the more hours a day it is switched on, the more rapidly you will consume batteries.
The batteries themselves are a major factor. Batteries of the 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 drain their stored energy unless they’re inserted into a hearing aid that is turned on, and some (such as zinc-air batteries) will start to burn power the moment you remove 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 considering new hearing aids, it’s a wise idea to do some research on the different models and the types of batteries they use to help you make the best choice. The same research recommendation holds true if you have an existing hearing aid and are searching for the batteries with the best performance for it; you can uncover a great deal from consumer ratings and comparative reviews.
Thankfully, when shopping for hearing aid batteries, the companies that manufacturer them have made things a lot easier for you by standardizing their sizes and color-coding each size; the same color codes are used by all hearing aid battery manufacturers. See the estimated battery life below to get a basic idea of how long batteries of each size should last:
- 80 hours – Yellow – Size 10
- 175 hours – Brown – Size 312
- 240 hours – Orange – Size 13
- 300 hours – Blue – Size 675
To ensure the longest life for your hearing aid batteries when they are in the hearing aid, turn the device off when you are not wearing it. Store your unused batteries at room temperature, indoors, and in their original, unopened packaging to ensure their longest possible life.
