Well, I operate of hours at lunch periods and on tops of mountains with
my 509 argonaut.. both CW/SSB and have no problem with the car off.. I
also use a small 4ah gel cell that I picked up at a ham fest for $5.00
and that will run for hours with my small CW transceivers.. I have gone
for days with the 7ah battery.

Many times in the Smokeys I will have a few QRP transceivers in a case
and bring my portable PVC vertical and pull over and operate using a
small gel cell.
