And I don't know where you got that last part but even with a dead short on a battery you will not drop to 0 volts immediately. Unless you mean over time. But you won't get to 0 before the battery has serious issues I'd imagine.

Anyways can't go wrong witb any nsb.

hours). At the 1 hour rate, the NSB40FT silver will support a load of
28.5 amps for 1 hour to an end point voltage of 10.5 volts
(28.5*1=28.5 Amp hours). The short circuit current is the load in Amps that will drive the
terminal voltage to zero
