A D battery has about 2 amp-hours at 1.5 volts.  If you put this into your
car battery most efficiently, and could retreave it without loss you would
get about 7 amp-minutes at 12 volts.  Your starter motor draws on the order
of 100 amps(depends on the car).  At best you could get a few seconds of
cranking power.
