Thanks also for the tip on putting the battery in a bag.
As I think more about the Paragon battery issues, the following come to
mind:
In a pinch, an alkaline battery could be used, if you make up an adapter
cable with a diode in series with it to prevent charging current from
going into the battery.
Maybe it would be better to relocate the battery outside the
transceiver. There is a place on the back for an RS-232 connector, if
that option is installed. One could fabricate a new cover plate with a
jack on it to connect to an external battery. This would also allow for
a bigger battery pack.
