Not a dumb question; it would seem intuitive that it doesn't.  And in 
fact some people have had success with getting very old batteries to work 
again by reversing them.

But the positive and negative grids of modern batteries have different 
formulations.  When the negative plates are used as positives, they 
literally crumble.  A reversed battery should be "forwarded" as soon as 
possible, and in any case will have a shorter life and lower capacity.
