Hearing Aid Batteries: What You Need to Know

Batteries are one of the key components to keep your hearing aids performing to their potential. While most battery sizes and colors are universal they are still designed to fit certain styles of hearing aids. They are easily available at most drug stores or department stores but rest assured Nola Hearing keeps them in stock for our patients. In case you are not able to head to our office, you can purchase new ones as long as you remember either the color or the number. If you are unsure, always pick up the phone to call our office at 504-309-8322 for assistance. We are happy to help!

The corresponding numbers and colors are as follows:

Corresponding Battery Numbers and Colors

10: Yellow

13: Orange

312: BROWN

675: BLUE

There are a few exceptions to this rule. Occasionally, there will be a smaller or larger lip on the batteries that will prevent the contacts inside your hearing aid from meeting, thus keeping the instrument from working properly or at all. 

If you find that you have purchased the incorrect size batteries or you are having another issue, please bring them to us and we will exchange them for you at no additional charge. That’s the Nola Hearing promise!

Important Battery Information

How long do hearing aid batteries last?

The standard hearing aid battery’s typically last anywhere between 3 to 22 days, depending on the type of hearing aid. It also depends on the battery type and capacity, how often you are using the hearing aid and how much Bluetooth streaming you do. There are a few tips to maximize the battery’s life.

How do I know when to change my batteries?

It depends on how often you use your hearing aids but you may need to change then once week or even twice a month. You can change the battery’s if the sound starts to become distorted or you find yourself having to turn up the volume more than normal. The low-battery beep or voice sound comes on which indicates the battery is low and needs to be changed.

What is the protective seal on the hearing aids for?

The small, sticky, colored tab on each battery is also a protective seal which is extremely important to your hearing aids battery life. They keep the batter from discharging power. A hearing aid battery starts to discharge as soon as the seal is removed so best practice is to not remove until ready to replace.

How can I maximize my battery’s life?

When not wearing your hearing air, turn it off or open the battery door at night. It’s best practice at night to allow moisture to escape as well as helping to keep the battery from corroding. If you find yourself not needing to use your hearing aids for a extended period of time, take the battery out completely. You can store them in the protective case for your hearing aids. You should avoid storing any batteries and hearing aids in extreme temperatures, hot or cold. They can quickly drain battery power and shorter a battery’s lifespan.

What about rechargeable hearing air batteries?

With technology ever so changing and evolving in hearing aid instruments, more and more allow rechargeable batteries or feature rechargeable technology. They are the most sought out feature for hearing aids as a late. Ask about which hearing aids we have available that feature rechargeable technology.

Useful Hearing Aids Battery Care Tips

  • Store hearing aid batteries at normal room temperatures out of any weather elements.
  • Do not refrigerate.
  • Wash hands thoroughly before handing batteries. Grease, oils, and dirt on the battery can damage your hearing aid.
  • Leave the battery door open at night to allow moisture to escape preventing the battery from corroding and damaging the hearing aid. 
  • Remove dead batteries immediately. A competely discharged battery can expand becoming difficult to remove and may cause damage.
  • Hearing aid batteries may suddenly lost power, so it’s smart to carry extra batteries at all times.
  • Keep extra batteries away from coins, keys, or other metal objects to prevent discharge of power.
