Hearing aid batteries

Colours, sizes and brand equivalents of hearing aid batteries

Choosing battery sizes can get confusing, as certain manufacturers will have different names for their products. But as each manufacturer is required to follow the colour-coded system, you’ll always know which is the right size for you, no matter what brand you choose. The four main sizes of hearing aid batteries are identifiable by the colour of their tabs – yellow, brown, orange and blue. So when you’re buying batteries for your hearing aid, all you need to look out for is your colour.

Tips for battery care

  • Turn off your hearing aids when you’re not using them (e.g. while you’re sleeping)
  • Leave the battery compartment door open overnight
  • Make sure you store your batteries at room temperature
  • Avoid keeping them in warm or humid places, like the bathroom
  • The best place to keep your batteries is in their sealed package – not loose in your bag or pocket

How long do hearing aid batteries last?

The shelf life of hearing aid batteries will depend on the size of the battery, hearing aid type, and how you use your hearing aid. For example, how loud it is and how long you wear them for each day. Generally, the larger the battery, the longer its lifespan.
