The Best Tips on How to Maximize Hearing Aid Battery Life

Published on Feb, 13, 2019

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.

Factors affecting hearing aid battery

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.

Steps to maximize hearing aid battery

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. 
  • Also, after inserting new batteries, let the hearing aids sit for at least two minutes before putting them in your ears.
  • To reduce the power consumption of your batteries when you aren’t using them, remove the batteries from your hearing aids each night.
  • Turn off advanced features like audio streaming when not in use, as these functions drain batter life fast.
  • Purchase batteries that are as fresh as possible. Look for expiration dates.
  • Open the battery door when the hearing aids are not in use. Besides minimizing battery drain, this allows moisture to escape.
  • Do not remove the sticky tabs from the batteries until you’re ready to use them.
  • Use a hearing aid dehumidifier; this protects both the hearing aids and its batteries.

Another option is to switch to rechargeable hearing aids and never have to worry about batteries again! The convenient, eco-friendly, and easy to use technology is readily available at a clinic near you.
