So how much current do you think they're actually capable of
delivering--say with the little battery fairly fresh and fully charged?


Too many variables. What is the amp hour rating of the battery?

Tiny in automotive terms.

What is the internal resistance of the switch?

Dunno

The resistance of the
cables?

Mine has 16mm² cables. The resistance of the alligator clamps is more
likely the limiting factor.

The resistance of the starter motor? The temperature? How
clean are the battery clamps, and what is the resistance of the battery
cables? The resistance of the starter solenoid?

Non of which matters since the power pack makers claim a maximum output.
