The difference between hearing and understanding

Hearing Aid Batteries

Today’s digital hearing aids are smaller and more powerful than ever. And powerful hearing aids need powerful batteries. No matter the type of hearing aid you wear, it is powered by a replaceable or rechargeable battery. As part of the fitting process, Hearing Rehabilitation Center will show you how to recharge or change your batteries.

Rechargeable hearing aid batteries

If your rechargeable hearing aid has a battery door, it uses a silver-zinc battery. This rechargeable battery is about the size of a standard disposable hearing aid battery. It charges in three to four hours, and a single charge can last 24 or more hours. This type of rechargeable battery needs to be changed once a year.

If your hearing aid does not have a battery, it uses lithium-ion technology. This battery is sealed in your hearing aid and will last three to four years. It takes about three to four hours to charge this battery fully and once charged, will last at least 24 hours.

If you ever have a problem with your rechargeable hearing aid battery, bring your hearing aids to Hearing Rehabilitation Center, and we can help.

Disposable hearing aid batteries

Disposable hearing aid batteries come in different sizes. Don’t worry; buying the right hearing aid battery is easy. Each size battery is color-coded, so you only need to remember the color. Disposable batteries are available in the following sizes:

  • Orange (#13): Used by ITE and BTE hearing aids. Batteries last about 240 hours. 
  • Yellow (#10): Used by ITC hearing aids. These batteries are good for about 80 hours of use.
  • Blue (#675): Used by full and half shell ITE hearing aids. Good for up to 300 hours. 
  • Brown (#312): Used by the smallest ITC hearing aids. Lasts about 175 hours.

Tips to extend battery life 

Whether you use disposable or rechargeable batteries, you want the most life from each charge or battery change. Follow these tips to extend battery life.

Always wash and dry your hands before changing batteries. You should always wash and dry your hands before handling your hearing aids as the oils and moisture from your hands can damage the battery and the hearing aid. 

If your hearing aids have a battery door, store your hearing aids when not in use with the battery door open and the device in the “off” position. This reduces the drain on the battery when not in use. 

Don’t store your hearing aids in the bathroom. The humidity and moisture from showers can speed corrosion and shorten battery and hearing aid life. 

Keep your extra batteries at room temperature. Do not keep batteries in the refrigerator. This can cause them to condensate and corrode.

Disposable batteries use zinc ion technology that only activates when exposed to air. So, when changing batteries, make sure the battery is fully exposed to air. Remove the tab and wait at least one full minute before installing the battery.
