PRIMARY HEARING AID BATTERY LIFESPAN CONSIDERATIONS

The question of precisely how long hearing aid batteries can be expected to last is not as easy to answer, as it seems, because battery performance hinges on a large number of factors. Battery life depends on the model of your hearing aid, and may vary widely across unique models created by the same manufacturer. The way you use your hearing aid will also influence battery life; the more hours a day it is switched on, the more rapidly you will consume batteries. There are even different battery lives in the same size of hearing aid battery depending on the manufacturer, and depending on if you’re buying that manufacturer’s “premium” line or their “normal” line. Battery life also depends on battery type; for example some types are only being drained when they are in a

hearing aid that is switched on, while other types (such as, zinc-air batteries) start losing stored energy as soon as you take away the adhesive strip on the bottom of the battery and they are exposed to oxygen, regardless of whether the hearing aid is on or not. Because the expense of hearing aid batteries adds up, if you are looking for a new hearing aid, you should do

some research to see which types and models of hearing aids are known for the best battery life, because that could influence your choice. Similarly, a little time invested in research may help you uncover better batteries for your existing hearing aids. Hearing aid and battery manufacturers have worked to make things simpler by standardizing their sizes and using specific color codes for each size, which is the same for every manufacturer. The following list of battery life is an approximation, of course, but it should give you a basic idea of how long hearing aid batteries of each size should last: • 80 hours – Yellow – #10 • 175 hours – Brown – #312 • 240 hours – Orange – #13 • 300 hours – Blue – #675

To ensure the longest life for your hearing aid batteries when they are in the hearing aid, turn the hearing aid off when you’re not using it. And to make sure hearing aid batteries you have already bought but have not used yet remain fresh and retain their power as long as possible, store them indoors in their original unopened packages, and at room temperature.
