How long do hearing aid batteries Last?

As all hearing devices use batteries it is important to consider their cost and replacement. In some devices, rechargeable batteries are available however, in the majority of hearing aids, you will need to replace the batteries every 10-30 days.

There are a range of variants that can affect how long your battery can last, these include; how much you use your hearing aid, what settings your hearing aid is on, the battery type and the type of hearing aid.

Are there ways to minimise battery drain?

There are multiple ways to minimise drain on your battery, which will reduce the number of times you have to change it.

This includes:

  • Remove the battery completely if you aren’t using your device for an extended period of time
  • Overnight, turn off your hearing aid and open the door to the battery compartment
  • Keep batteries away from coins or other metal objects which can discharge the batteries
  • Keep out of extreme hot or cold temperatures

How do I know if I should change the batteries?

While your batteries can lose charge very quickly, there can be several indicators that you need to change the batteries in your hearing device.

Some hearing aids emit a low beeping tone to alert you to the need of the batteries to be changed, other indicators include the sound you receive becoming distorted or all sound ceasing.

Due to the capacity of hearing aid batteries to quickly discharge it is a good idea to carry spare batteries with you at all times.

Your Hearing Technology Experts

Hearing aid batteries should be stored at room temperatures in a cool, dry place and away from other metal objects. It is important to remove dead batteries immediately as they can swell and become trapped in the battery compartment.
