I have this same very problem.  From my experience, I think this is 
Duo Battery Voodoo.  I have several batteries that I know are good 
(from previous use and conditioning).  however, I cant get one of my 
Duos to run off of any of them right now.  My PRAM charge is good.  I 
think you sometimes have to get the duo and battery "familiar" with 
each other.

Try this:  with the battery in, put the duo to sleep.  Then remove 
the AC and see if the battery can wake the unit up.  Try several 
times.

or

Try Battery Recondition.  If it doesnt work at first (crashes 
machine) do it again.  And again.  Between the recondition and teh 
sleep trick, you should be able to get the battery back in order.

Having a Lind Supercharger2 also helps.  It can help whip batteries 
back into shape.
