Thanks guys. BTW Autozone does NOT have them. Radio Shack ALWAYS had this stuff. My office is close to a KMART. Vacant for a year, took down the giant K this week. End of an era. When I was in college the Kmart had a talking mynah bird. Taught by college kids he could swear in English and Spanish.

Well I went to the website of the people who made your doodads.

That gave me an image of Duracell Medical N Battery.

So I googled where to buy Duracell Medical N Battery and got tons of hits.

Try These
.
Hopefully one of these sellers will have them in stock and get them shipped out to you asap.

Clean It Supply seems to have them, they have their phone number listed, call them.
Best wishes to you.

Thanks Gene. BTW I too had Depression Era parents. I am usually prepared. I had not been to the Range in a long time, and lo and behold one of the earpieces started whistling when I picked it up.

^^^^^ You're welcome
