Hearing Aid Batteries and Accessories

Over time, the costs of hearing aid batteries can add up, especially if you don’t take care of them properly. Here are a few quick tips to keep your batteries longer.

How to Extend the Life of Your Hearing Aid Batteries

Figure Out What Is Draining Your Batteries

Usually hearing aid batteries work well for 3 to 6 days. If your batteries seem to fizzle out before then, consider whether you’re doing things that are draining them quickly. Here are the most common culprits.


  • Overusing advanced options. Advanced features can make the difference between hearing and hearing clearly. Don’t be afraid to use them…just make sure you’re only using them when you need them.
  • Changes in altitude. Switching from high to low altitudes can drain batteries, so consider whether they are worth wearing on the ski slopes.
  • Exposure to moisture. If you like wearing your hearing aids while working out, make sure to dry and store them correctly. In fact, if your hearing aid is exposed to moist environments on a regular basis, think about getting a dehumidifier.

Don't wait!

Early treatment is the most effective treatment.

A Few More Tips to Get More Out of Your Hearing Aid Batteries

  • Pull the tab only when you’re ready to use the battery. Once you expose the battery to air it is activated and will begin to drain.
  • Wait a few minutes before installing your battery. Once you’ve pulled the tab, let the battery sit on the counter for a few minutes to make sure it gets enough air before you install it. Most hearing aid batteries have zinc, which gets its charge by interacting with air. If you install it before it fully “charges” you’ll get less out of it.
  • Keep an eye on the expiration date. It’s so tempting to buy in bulk or on sale, but if you aren’t careful your batteries may be old before you even take them out of the box.

    Sensorineural Hearing Loss
    Sensorineural hearing loss is fairly common and might explain why you can hear a pin drop, but not be able to make out what your partner is saying. You’re born with tiny hairs called cilia in your inner ear that move when sound waves are present. Nerves translate the movement of these tiny hairs into information that goes to your brain where it gets interpreted into distinct sounds and frequencies.

    The better the movements are interpreted, the more easily you’re able to hear distinctions between sounds such as “D” and “T” or hear letters like “S”, “H” and “F”. Unfortunately, the cilia are extremely delicate and can be harmed by loud noise or other trauma.

    Cilia also help your brain determine how loud a sound is, where it’s coming from, and how far away it is.

    The Most Common Causes of Sensorineural Hearing Loss
    Sensorineural hearing loss happens when these tiny hairs are damaged. Often, this type of hearing loss is gradual, which is why many people associate it with aging. It’s thought that animals are able to regrow these hairs and regain their hearing when their cilia get damaged, but humans don’t seem to have this ability naturally.

    Common causes of sensorineural hearing loss are:

    Loud sounds
    Head injuries or other trauma
    Diseases like diabetes or autoimmune disease
    High blood pressure
    Some medications
    How to Deal with Sensorineural Hearing Loss
    While there are no current medical treatments to heal cilia, you can successfully address sensorineural hearing loss with hearing technology such as hearing aids.

    Why wait? You don’t have to live with hearing loss.
