In the real world, I've seen golf car batteries produce around 1300-1500 
amps for short periods (that's approximate; it was kind of hard to read 
the 
ammeter at that point). 

The internal resistance of a golf car battery is about 0.003 ohms.  By 
Ohm's 
law, I = E / R => 6 / .003 = 2000.  So a golf car battery should be able 
to 
produce 2000 amps into a short circuit. 

But it isn't gonna like it!  If you ask a golf car battery to deliver more 
than about 500 amps very often and for long periods of time, it tends to 
live a short, unhappy life.
