Hearing aid batteries and maintenance


It is important that you look after your hearing aid/s and clean them regularly. This will prolong their life and make sure they are in good working order when you come to use them.

There are two main types of hearing aid.

  • Behind-the-ear (BTE) hearing aids
  • In-the-ear (ITE) hearing aids

Behind-the-ear (BTE) hearing aids
Ideally, you should wipe the earmould with a soft dry cloth daily and remove and wash the earmould and tubing (NOT the hearing aid itself!) in warm soapy water and then rinse them on a weekly basis. Leave the mould and tubing to dry before fitting them back onto your aid. If you do not know how to disconnect the tubing from your hearing aid consult the organisation who supplied it. If you have two hearing aids, make sure that you know which earmould belongs to which hearing aid so that you can put them back together properly. 3,4

The tubing on your hearing aid will need to be changed every three to six months before it hardens, splits or causes problems. Your hearing aid centre or dispenser will advise you on how to change the tubing, or do this for you. 3

In-the-ear (ITE) hearing aids
This type of hearing aid has no earmould to detach. The entire aid should be cleaned with a dry cloth. Make sure that it does not come into contact with any liquid. Often the aid comes with a wax pick, which is a small piece of equipment for removing wax from the opening at the end of the hearing aid. The instructions that come with the hearing aid should say in detail how to clean it. 3


It is a good idea to have spare hearing aid batteries to hand at home and to carry them with you if you're going out. If the sound from your hearing aid gets fainter, disappears, becomes crackly, fuzzy or distorted, you should change the battery. Some aids give a warning signal (a bleeping or 'fluttering' sound) when the battery is just about to run out. A standard battery for a hearing aid lasts approximately 5 to 14 days, depending on the type of hearing aid, type of battery and how much the hearing aid is used.1

If you have an NHS hearing aid, new batteries are supplied free of charge. You can obtain new batteries from any NHS hearing aid centre but need to take your hearing aid record book with you for the audiologist to see which batteries you need and record how many batteries they give you. Someone else can collect batteries for you as long as they take your record book. Alternatively, you may be able to obtain batteries from the hearing aid centre by post or at a local health centre, ask your hearing aid centre for details. 2,3

Hearing aid battery testers and tools to help you extract and replace the battery are available.

Changing the battery

Many hearing aids have the battery compartment at the bottom of the hearing aid. If you push a little ridge then the battery swivels out into view as shown by the photo to the right. When replacing the battery follow the hearing aids instruction manual carefully. Many hearing aid batteries come with a paper tab stuck to the battery. This tab prevents the battery from draining while it is being stored. When you install the battery remove the paper tab.

To prolong the battery life switch off your hearing aid when not in use. If your not going to use it for a long period of time, you should remove the battery.1,2
