The question of precisely how long hearing aid batteries can be expected to last isn’t as simple to answer as it seems, because battery life depends on a large number of factors. Battery life will depend on the model of your hearing aid, and can vary widely across models created by the exact same manufacturer. The actual life span of a hearing aid battery also depends on the amount of time each day that the hearing aid is turned on. Not surprisingly, the more you use the hearing aid, the more rapidly the batteries will be used up.

There are even different battery lives in the exact same size of hearing aid battery depending on the manufacturer, and depending on whether you are purchasing that manufacturer’s “premium” line or their “normal” line. Battery type is another main factor in longevity. For example, zinc-air batteries will start to lose stored energy the instant you remove the tab on the bottom and will continue losing power even if the hearing aid is turned off while other battery types will only drain when they’re inside a hearing aid that is powered on.

If consider 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 determine the best choice. If you have an existing hearing aid and are searching for the most long-lasting batteries for it, the Internet can be a wonderful source of comparative ratings and reviews.

Hearing aidand battery manufacturers have worked to make things easier by standardizing their sizes and using specific color codes for each battery size that is the same for every manufacturer. Take a look at the estimated battery life below to get a basic idea of how long hearing aid batteries of each size can be expected to last:

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

For the longest battery life, remember to turn your hearing aid off when you are not using it. Store your unused batteries at room temperature, indoors, and in their original, unopened packaging to ensure their longest possible life.
