I'm wondering if @bobbiefriend received criticism from someone for changing hearing batteries in public. I wear hearing aids in both ears. By the time I get the signal that the battery in a hearing aid is going to quit I have about 30 minutes to change the battery. I need my hearing aids to hear effectively in public places where there is lots of background noise. The batteries are so tiny that I need a table or other safe surface. Like Julie said, how is this any different than cleaning your glasses?
