battery voltage

What is the minimum voltage we need to see at start-up. I have a SCT TSX and it is showing 11.5-11.7 v while key is in the on position and while cranking jumps to 10.7 v and after the truck starts it stays roughly at 12.5v for half a minute or more then it jumps to 13.7 - 13.9v. Is it the glow plugs dragging this down?
