Batteries

A battery provides electrical power to the hearing aid. The estimated battery life for a button battery varies with each device and its power needs. Estimated battery life is available from your audiologist. Batteries are made by several manufacturers. The hearing aid will require the same size battery every time, however the manufacturer of the battery does not have to be the same every time. An easy way to remember the battery size is by the colour of the sticker on the back of the battery:
