Hearing Aid Batteries

Hearing aids get their power from batteries. Depending on the hearing aid, it may be powered by disposable zinc-air batteries or rechargeable silver-zinc or lithium batteries. No matter what type of hearing aid battery you need, Modern Audiology carries a full range of batteries to keep you powered up and ready to engage in life around you.

Rechargeable batteries

You can expect silver-zinc rechargeable batteries to last about a year. When they can no longer hold a charge, it’s time for a replacement. Just bring your hearing aids in, and Modern Audiology can change out the battery while you wait.

Lithium-ion batteries are long-lasting rechargeable batteries. The battery itself can last up to five years, and a single charge can power your hearing aids for more than a day.

Hearing aids with rechargeable batteries are more and more popular. That’s because new battery technology produces a battery that can hold a charge longer than ever before. In addition, people with vision and dexterity problems are freed from the hassle of handling small, button-sized batteries and fumbling with battery doors. Talk to the audiologist at Modern Audiology and see if hearing aids with rechargeable batteries are right for you.

Disposable batteries

Despite the rising popularity of rechargeable batteries, disposable batteries are still the most popular way to power hearing aids.

Shopping for hearing aid batteries is easy. Each size is identified by a number and color-coded to avoid confusion. The smaller the hearing aid, the smaller the hearing aid battery and the shorter the battery life. Larger hearing aids with more features require larger hearing aids. The most common disposable hearing aid battery sizes are as follows:

  • #675 Blue  batteries are the largest of the disposable hearing aid batteries. They are used by the largest hearing aids and can last up to 300 hours.
  • #13 Orange batteries power behind-the-ear (BTE) and in-the-ear (ITE) hearing aids. These batteries can provide up to 240 hours of use
  • #10 Yellow batteries are used by in-the-canal (ITC) and completely-in-canal (CIC) hearing aids. The yellow battery provides about 80 hours of use before replacement.
  • #312 Brown batteries are the smallest batteries for hearing aids. They are used for ITC and CIC hearing aids. You can expect about 175 hours of use before a battery change is necessary.
