Rich,
I agree that the two 6 volt batteries in series would double the voltage
and not the amperage (basic electronics). However, I'm not sure that
cranking amps and amperage equate to the same thing.
Cranking amps actually refers to a power potential. Or so I believe. It is
a measure of a certain amount of power as a function of time. I'll ask the
battery guy when I decide to order. Unless someone on the list can offer
their expertise on the subject that knows how cranking amps are determined.
I just know that here in Montana, a 12 volt battery doesn't rate unless its
500+ cranking maps, although a MG may start on less at 20 below zero.
