I have an old TPX 720 handheld radio. It was sitting for 20 + years
and the rechargable batteries were shot. They are 1.2 v nicads, 10 of
them. Before I go out and buy more, does anyone know if I can just
put regular aa cells in it to see if it works? The nicads are 12
volts total, and the dry cells would be 15. I don't want to fry the
radio.

Thanks

Kurt
