I'd say that sounds like consensus!  Optimistic = 16 hours, pessimistic, 
probably under 4.  Although, I've never seen a battery in reasonable 
shape not able to run a car stereo for several hours.  Not to say it 
could start a car afterwards...

Anyway, aren't there going to be many vehicles there?  Anything wrong 
with jumping the "stereo" battery with a running car once in a while? 
Or rotating the stereo battery in and out of a car before it's too 
whacked to start the car?  Or using two batteries? etc. etc.
