Battery testers are available if you want to buy one. This is a device that has proved to be very useful to users of Hearing Aid. It is essential that you know when to change the batter because the quality of your sound depends on the power of the battery. It is not always easy to tell when the battery is running low.

These devices can also be used to ‘troubleshoot’. You could be changing the battery unnecessarily. The actual problem with the hearing aid might not the battery at all. It may be the unit itself.
