How do I insert the batteries?
The first step is to remove the protective foil from the batteries. It takes around two minutes after this for your battery to reach full power, so you might choose to wait before you insert them into your hearing aids. Make sure you insert the batteries with the minus and plus sides the right way round. If you find that the battery compartment won’t close, or is difficult to close, it’s usually because you’ve got the plus and minus back to front!
If your hearing aid doesn’t seem to be working even after you’ve fitted the new battery, try checking that there’s no contamination in the battery compartment, as this can interfere with the connection. You could also try a different battery in case it’s a manufacturing problem.
