Hearing aid batteries generally last around seven days, however their lifecycle can be as short as five or as long as 10 days. If you’re keen to extend the life of your new hearing aid batteries, you’ll be pleased to hear there’s plenty you can do.
Leave the tab on
Your new hearing aid batteries should come with a plastic tab. Once the tab is removed, the zinc in the battery interacts with the oxygen in the air which is what makes the battery active. Only when you are ready to use the battery should you remove the tab. Then let the battery sit for one minute to power up before inserting it into the hearing aid battery compartment.
Grease and dirt can damage both your batteries and hearing aids and shorten their lifespan. Ensure your hands are clean and dry before handling batteries.
Keep moisture out
Moisture can damage both your hearing aid and its batteries. When not in use, for example overnight, open the door to the battery compartment to allow moisture to escape and keep the batteries dry.
Turn off your hearing aid when not in use
Sounds obvious, but it’s something many people forget. If you leave your hearing aid switched on when you’re not using it, you will waste battery power. Make a habit of always switching off your hearing aids as soon as you remove them.
Keep track of how long your hearing aid batteries are lasting. If they run out before five days it could be a sign that your hearing aid needs repair, so if you notice this is happening check with your local hearing centre.
