But if you want to DOUBLE your COLD CRANKING AMPS... Hook the 2 batteries up the same way as described above BUT go to the starter (+) off of one battery and ground (-) off of the other battery.

Hahah WHAT?! U need to open some books. 2 batterys parralled stays 12v and combines both batterys cca. The way u describe leaves insuffent grounds. BOTH BATTERYS NEED A CRAP LOAD OF GROUNDS AND EITHER A COMMON BUT EQUIL + JUNCTION POINT or EQUAL POSITIVE BRANCHES OFF POSTS. To say neg off one and pos to starter is a frog leap away from a in series system. Your 2000 posts are impressive, but if they contain incorrect instructons whats the point?

The diagram below is how I've always hooked up my batteries to DOUBLE MY COLD CRANKING AMPS.
I've ran like this for over 30 years and have never had a problem.
