My C4500 6.6 needs new batteries... It's a 2005 with orginials Delco 750cca (2). What replacement batteries do you recommend? Stay with the Delco or is there others as good or better?
Also, is the setup a parallel or series?
Thanks,
Dan

I replaced mine with a set from Costco. Termination is a bit different but it can be handled. The batteries are in parrallel.
