The question of just how long hearing aid batteries can be expected to last isn’t as easy to answer as it seems, because battery life hinges on many factors. Battery life depends on the model of your hearing aid, and may vary widely even in models developed by the exact same manufacturer. The life of a hearing aid battery also hinges upon the amount of time each day that the hearing aid is turned on. Unsurprisingly, the more you use the hearing aid, the more rapidly the batteries will deplete.
Additionally, there are differences in battery life between battery manufacturers, and the exact same manufacturer may have different lines of batteries, some that last longer than others. Battery life also hinges on battery type; for example some types are only being drained when they are inside a hearing aid that is turned on, and other varieties (for example, zinc-air batteries) start losing power as soon as you take away the adhesive strip on the bottom of the battery and they’re in contact with oxygen, regardless of whether the hearing aid is turned on or not.
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 could influence your choice of 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 wonderful 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 that is the same for every manufacturer. Take a look at the estimated battery life below to get a general idea of how long hearing aid batteries of each size should last:
- Yellow – #10 – 80 hours
- Orange – #13 – 240 hours
- Brown – #312 – 175 hours
- Blue – #675 – 300 hours
Remember to turn your hearing aid off when you aren’t wearing it for the longest battery life. And to make sure hearing aid batteries you’ve already bought but have not used yet remain fresh and retain their power as long as possible, store them indoors in their original unopened packaging, and at room temperature.
