Introduction

Hearing Aid Batteries: Size and Information

Hearing aid batteries are an essential part of your hearing aids. Without batteries, your hearing aids won't be powered and won't work. There are different types and sizes of batteries that are used for different models of hearing aids.

Batteries for hearing aids are much smaller than typical batteries by necessity. That's because hearing aids are very small devices. Despite their size, hearing aid batteries are able to power very technologically advanced hearing aids.

Choosing size

Hearing Aid Battery Sizes

There are four different battery sizes that you can get for your hearing aids. The size is helpfully indicated by colour coding across all brands and hearing aids. The reason why there are different sizes of batteries is because of the different types of hearing aids.

Larger and more powerful hearing aids, such as Behind-The-Ear hearing aids, require larger batteries. Smaller hearing aids, like In-The-Ear hearing aids, need smaller batteries so the hearing aid can still fit in your ear.

Yellow size 10 hearing aid batteries are the smallest battery size at 5.8mm x 3.6mm. They are meant for smaller, less powerful hearing aid models:

  • Receiver-ln-The-Ear (RITE) hearing aids
  • Completely-ln-Canal (CIC) hearing aids

Due to their smaller size they also have the shortest battery life. One size 10 battery will last around 3 to 5 days, depending on the daily hours of use.

  • Avoid hot, humid areas and do not refrigerate.
  • Wash hands before touching batteries to prevent contamination.
  • Keep batteries away from metal objects.
  • Remove dead batteries promptly to avoid corrosion.
  • Clean your hearing aids regularly for optimal performance.

Extend battery life

Extending the life of your hearing aid battery

To maximize hearing aid battery life:

  • Keep battery doors open when not in use.
  • Remove labels only before use.
  • Use a dehumidifier overnight for your hearing aids.
  • Avoid expired batteries; purchase what you'll use timely.
  • Use older batteries first to prevent expiry.
The two types of Hearing Aid Batteries

Hearing Aid Battery Types

There are two types of hearing aid batteries: disposable zinc air batteries and rechargeable batteries. There are pros and cons for each.

Disposable Zinc Air Batteries

Disposable zinc air batteries are made for one-time use. After the power runs out, you need to replace and dispose of them. You should never just throw out used hearing aid batteries in the garbage, as they are bad for the environment. Instead, you can drop them off at our clinics when you pick up new battery packs as part of our free exchange program. We make sure the batteries are properly recycled.

Pros:

  • Most hearing aid models are meant to use disposable batteries.
  • They are easy to use and don't require any recharging station.

Cons:

  • They aren't as environmentally friendly.
  • You will need to constantly buy replacement batteries and dispose of used ones.

Rechargeable Lithium-ion Hearing Aid Batteries

Rechargeable technology is becoming more popular, but typically the batteries are not removable from the hearing aid unit. Instead of removing batteries to recharge them, you simply place the entire hearing aid in the charging station.

Lithium-ion batteries are great because they have a long shelf life. You can recharge and reuse them for a long time before needing to replace them with new batteries.

Pros:

  • More environmentally friendly.

Cons:

  • Battery replacement needs to be done by the manufacturer.
Replacing Batteries

Replacing Hearing Aid Batteries

  • You'll hear a warning sound when the battery is low.
  • Place the battery and hearing aid on a clean, flat surface.
  • Remove the battery's label and wait a few minutes before use; it's on the shiny, positive side.
  • Start using the battery immediately after removing the label to prevent power loss.
  • Store used batteries in a container to return to our clinic.

Instructions vary by hearing aid type; contact your clinic for help or watch our video guides for BTE and ITE models:

Disposing and donating

Disposing and donating of hearing aid batteries

When replacing hearing aid batteries:

  • Safely dispose of used ones, as throwing them away may be illegal.
  • Store used batteries in a sealed container to prevent loss or accidental ingestion.
  • Bring old batteries to our clinic for eco-friendly recycling when getting new ones.

We accept donations of unused hearing aid batteries at our clinics for clients in need, whether due to discontinued use or a loved one's passing.
