"Ok, now we're going to talk about general care and maintenance. We'll start with the batteries. There are four--basically--four different types of batteries for hearing aids: 675 blue, size 13 orange, size 312 brown, and size 10 yellow. The 675 is the battery that we use in the larger unit, and it's fairly easy to change. You just open the door, take the battery out, take the tab off the new battery, and put it back in.
