Batteries for hearing aids are disc shaped and about as small as an aspirin.  There are two choices when it comes to batteries and they are “disposable” or “rechargeable“.  If you get disposable batteries, then you need to open the battery door nightly and close the battery door in the morning before you use it.  When you select rechargeable batteries, then you never need to open the battery door.  Lansdowne Hearing will explain more about batteries below.
