How to replace batteries in hearing aids

It is very likely that as a live-in carer you will be caring for a client who wears hearing aids. These are great while they are working, but eventually the batteries will need to be replaced.

Typically, the batteries in a hearing aid will need to be replaced every three to ten days. This depends on how much they are used and the style of the hearing aid. 

What should you hear?

On many hearing aids you will hear a few short beeps when the batteries need changing. This beeping is repeated at intervals until the battery has completely run out.

You may also hear four beeps. This is often the last warning before the battery is completely flat and may come right after the pre-warning or within a few hours.

What happens after the battery is changed?

Once you have put a new battery into the hearing aid and closed the battery door, you should hear a short jingle. The hearing aid may also whistle when held in your hand.

Note that when not in use it is better to turn the hearing off. This is done by simply opening the tiny door. This will ensure that the battery lasts for longer.

How to test the hearing aid battery

There are two ways to do this, namely with a battery tester and without one.

With a tester

Place the hearing aid battery on the tester surface, making sure that the positive (+) side is facing upwards. Now slide the battery in the direction of the small arrow and you should be able to read the result on the display area.

Without a tester

Place the battery into the hearing aid and close the door. Close your hand over the hearing aid and place it near your ear. You should hear a squealing sound coming from the hearing aid. This is an indication that the battery is still working properly.

Final thoughts

Once you have changed the batteries, they should be discarded immediately and safely according to local regulations where you are staying.

It is very important to note that batteries can be fatal if swallowed by children and pets, and you should keep them out of reach of both animals and children.
