A fresh hearing aid battery will keep your device working to its maximum capability. It’s always a good idea to carry a spare or two with you, too, so you can make a quick change if your power begins to run down.

What you should know about hearing aid batteries?
Keep your batteries sealed until you’re ready to use them. If you remove the label, they will start to lose power and be exhausted after 4 weeks or so, even if you don’t use your hearing aid at all during that period.

Store your batteries in a cool, dry place away from children and pets; batteries are dangerous if swallowed. And store your hearing aid with the battery door open to make sure it’s not using battery power when it’s not in your ear.

When it’s time to change to a new battery, remove the label and let the battery ‘breathe’ for 60 seconds before placing it in your hearing aid. Change your hearing aid battery in a flat, uncluttered place with a soft surface; a kitchen table with a tablecloth is ideal.
