The question of precisely how long hearing aid batteries can be expected to last is not as simple to answer as it seems, because battery life is dependent upon a large number of factors. One factor is the company manufacturing the hearing aid. Battery performance varies by manufacturer and also across models from the same company. The way you use your hearing aid will also impact battery life; the more hours each day it is switched on, the more often you will use up batteries.

The hearing aid batteries themselves are a major factor. Batteries of the same size from different manufacturers will have distinct lives. And there will be variation within one battery manufacturer if they offer premium or extended-life lines. Battery life also hinges on battery type; for example some varieties are only discharging power when they are in a hearing aid that is on, and other types (such as, zinc-air batteries) start burning stored energy as soon as you remove the adhesive strip on the bottom of the battery and they’re exposed to oxygen, whether the hearing aid is on or not.

Because the expense of hearing aid batteries adds up, if you’re looking for a new hearing aid, you should do some research to see which types and models of hearing aids have the best battery life, because that could influence your decision. Similarly, a bit of time invested in research may help you find better batteries for your existing hearing aids. Fortunately, 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 identical color codes are used by all manufacturers. The times listed below for each size are approximations, but can give you a general idea of how long batteries of each size should last given standard use:

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

Remember to turn your hearing aid off when you are not using it for the longest battery life. To ensure the longest shelf life for batteries you have purchased but have not used yet, store them indoors, at room temperature, and in their original, unopened packaging.
