Hearing Aid Batteries

Batteries are the source of life for your hearing aids, and they are necessary for proper functionality.

Understanding how hearing aid batteries work will help you keep your devices functioning effectively day in and day out.

Take a look at these important facts to get a better understanding of hearing aid batteries and how to use them.

  • Most hearing aids use disposable zinc-air batteries. These batteries are all coded by color and number, so replacing your hearing aid batteries is a simple and easy-to-understand process. Different sizes, styles, and models of hearing aids use varying types of batteries. The most common types are 5 (red), 10 (yellow), 13 (orange), 312 (brown) and 675 (blue).
  • Hearing aid batteries are easy to buy. All common types of hearing aid batteries are available from online retailers and in most drug stores. You can also get your device batteries directly from your audiologist’s office.
  • Zinc-air batteries require oxygen to power your hearing aids. These batteries come in air-sealed packaging, so they aren’t activated until you open the box. Once the package’s seal is broken, the batteries should be left in the open air for at least 60 seconds before insertion into your hearing aids.
  • Hearing aid batteries usually last 5–10 days. Because their lifespan is so short, you should always have two or more spare batteries on hand for unexpected replacements. Before changing the batteries in your hearing aids, wash your hands well to avoid transferring dirt or grease, which can decrease the lifespan of the battery.
  • There are several possible signs that your battery needs replacement. While it’s easy to understand when your hearing aid battery is completely dead, other signs indicate it’s time to replace your battery as well. These include reduced volume, sound distortion or occasional beeps, which let you know your battery is low on some hearing aid models.
  • You can take steps to extend the life of your batteries. Batteries kept in a dry, room-temperature environment will last longer than batteries exposed to extreme heat or cold. In addition, you should store batteries away from metallic and magnetic objects, including coins and keys, to avoid discharging and short-circuiting. Once batteries are in use, you can increase their lifespan by turning off your hearing aids and opening their battery casings at night.
  • Lyric hearing aids have a battery lifespan of four months. If changing your hearing aids’ batteries weekly sounds like a challenging task, it’s worth considering the many benefits of Lyric devices. These cutting-edge disposable hearing aids are implanted deep within the ear and worn for about 120 days before replacement.
    • With a better understanding of your hearing aids’ batteries, you can maximize the value and effectiveness of your devices.
