How do I know when the batteries are flat?
When the batteries have lost all charge (or ‘gone flat’), the hearing aid will simply turn itself off.
Most recently fitted hearing aids are fitted with an alert signal which will activate just before the battery goes flat. The warning alert (usually a series of beeps) is set by your audiologist at the time of programming your hearing aid. If your hearing aid switches off and you did not receive a warning signal, please check with your audiologist if your hearing aid has this feature.
