Even though the battery life for hearing aids might sound like an easy question to answer, in truth it hinges on many factors. Just how long a battery will last is dependent upon who manufactured the battery, and can even vary across models from the same manufacturer. The actual 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 your hearing aid, the faster the batteries will be used up.
The hearing aid batteries themselves are a key factor. Batteries of the same size from different manufacturers will have distinct lives. And there will be variance within one battery manufacturer if they offer premium or extended-life lines. Hearing aid battery life also depends on battery type; for example some types are only discharging power when they are in a hearing aid that is on, and other types (such as, zinc-air batteries) start losing power as soon as you take away the adhesive strip on the bottom of the battery and they are in contact with oxygen, regardless of whether the hearing aid is on or not.
If you are in the market for a new hearing aid, you may 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 purchase. If you have an existing hearing aid and are searching for the longest lasting batteries for it, the Internet can be a fabulous source of comparative ratings and reports.
Thankfully, when shopping for hearing aid batteries, the companies that manufacturer them have made things a lot simpler for you by standardizing their sizes and color-coding each size; the exact same color codes are used by all hearing aid battery manufacturers. 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 – Size 10 – 80 hours
- Orange – Size 13 – 240 hours
- Brown – Size 312 – 175 hours
- Blue – Size 675 – 300 hours
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 batteries you’ve already purchased 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.
