How to Prolong Hearing Aid Battery Life

One of the most common questions asked by people who use hearing aids, particularly first time wearers, is what they can do to maximize the lifespan of their hearing aid batteries. Hearing aid batteries may be relatively inexpensive and create just a small amount of waste when disposed of, but it’s still a good idea for both the pocketbook and the environment to help these little batteries last as long as possible.

A number of different factors can affect the length of your batteries’ lifespan. Size and activity level have the most obvious impact: smaller batteries (used in smaller hearing aids) will drain faster, while hearing aids which use more advanced, energy-intensive features for longer periods of time will also use up battery power more quickly. Batteries are strongly affected by humidity, either too much or too little, and can sometimes be impacted by extreme temperatures and altitude levels.

While you naturally will not want to compromise on your hearing aid’s size or features simply to get an extra hour or two of life out of your batteries, there are a few other simple steps you can take to help increase battery longevity.

  • The battery contacts inside your hearing aids should be kept clean and dry to avoid corrosion; you can dry them off using a cotton swab.
  • Fresh batteries should always be stored in a dry place at room temperature to prevent the protective stickers from prematurely peeling off.
  • Before inserting a new battery into your hearing aid, let it sit sticker side up for a few minutes with the sticker removed; this helps the battery come to full activation before you begin using it.
  • To reduce the power consumption of your batteries when you aren’t using them, remove the batteries from your hearing aids each night.


Also keep in mind that rechargeable batteries are a very convenient solution available in many of our hearing aid devices.
