All batteries have some internal resistance. Bigger ones usually have less than
little ones. When you connect two batterys in parellel that resistance is cut
in half. That resistance is part of the circuit just like external resistance
and when you connect to a big load which requires lots of amps the voltage drop
across the internal resistance becomes significant and it is subtracted from
the voltage that the battery puts out. Remember V=IR

plus, minus to minus; Bill, if that was my car, I'd
put the biggest battery I could get in there, to crank that baby!" And
he was right, the biggest CCA battery available cranked it and ran it
better than a smaller CCA alternative. Bill
