Even though it might seem to be a straightforward question to ask just how long hearing aid batteries are good for, it isn’t. Precisely how long hearing aid batteries last depends on numerous factors. Just how long a battery lasts is dependent upon who manufactured the battery, and will vary between hearing aid models from the same manufacturer. The actual life of a hearing aid battery also depends on the length of time the hearing aid is powered on. Not surprisingly, the more you use your hearing aid, the faster the batteries will be depleted.
Additionally, there are variations in battery life between battery manufacturers, and the same manufacturer may have different lines of batteries, some which are supposed to last for a longer period of time than others. Battery type is yet another main factor in longevity. For example, zinc-air batteries will begin to burn power the second you remove the tab on the bottom and will continue to lose charge even if the hearing aid is powered off while other types will only discharge when they’re in a hearing aid that is turned on.
If consider new hearing aids, it’s a good idea to do some research on the different models and the types of batteries they use to help you make the best choice for your lifestyle. Similarly, a bit of time invested in research may help you locate longer-lasting batteries for your existing hearing aids. Thankfully, when shopping for hearing aid batteries, their manufacturers have made things a lot simpler for you by standardizing their sizes and color-coding each size; the identical color codes are used by all manufacturers. The following list of battery life is estimated, of course, but it should give you a general idea of how long batteries of each size should last:
- Yellow – #10 about 80 hours
- Orange – #13 about 240 hours
- Brown – #312 about 175 hours
- Blue – #675 about 300 hours
Don’t forget to turn your hearing aid off when you are not wearing it for the longest battery life. Store your unused batteries at room temperature, indoors, and in their original, unopened packaging to ensure their longest possible life.
