Modern hearing aids have come a long way, providing incredibly clear sound quality for those with hearing issues. Choosing the right batteries for your hearing aids will help to ensure that the quality of sound is maintained for as long as possible before you need to change the batteries. There are a range of different batteries available for use in hearing aids. In order to choose the right type, it is important to understand their usage, lifespan, and key features that will allow you to make an informed decision.

Types of hearing aid batteries

Batteries for hearing aids can be broken down into two main types, disposable and rechargeable.

Disposable batteries: Traditional zinc-air hearing aid batteries are activated by exposure to air. There are four standard sizes, and each is designed for a specific model of hearing aid. The larger batteries have a longer lifespan. There is an industry standard colour code to help you find the right size:
Size 10 = yellow – used in small hearing aids, these are usually expected to last for periods of 3-7 days
Size 13 = orange – suitable for use in larger hearing aids, these last between 6-14 days on average
Size 312 = brown – these are common for use with in-the-ear (ITE) and behind-the-ear (BTE) models and last between 5-10 days
Size 675 = blue – these are the batteries for powerful hearing aids and can last anywhere from 9-10 days

Rechargeable batteries: These are becoming a more popular choice and eliminate the need for such frequent battery changes, as they can last much longer.

What to consider when looking for batteries
There are several things to think about when it comes to looking for the right batteries for your hearing aid. These include:

  • Compatibility: Make sure that the size of the battery you choose matches the model of hearing aid that you have
  • Usage habits: If you have streaming features and frequent use of your hearing aids, then your batteries will drain much faster
  • Dexterity and handling: If you have limited dexterity, you should consider that smaller batteries can be trickier to manage.
  • Environmental impact: Batteries that are rechargeable are more environmentally friendly and can help to reduce waste. If rechargeable batteries are not for you then ensure that you dispose of your used hearing aid batteries correctly.

Maximise the life of your batteries
If you want to get the most out of your batteries, make sure that you store them properly in a cool, dry place. You should only remove the tabs when you need to use them, as zinc-air batteries activate when exposed to air. You should also turn off your hearing aids when not in use and avoid moisture to help conserve battery life.

When choosing hearing aid batteries, consider all the factors for optimal performance and longevity. With the right care, your batteries should last a little longer while still providing great hearing assistance.
