batteries

Ok..'84 f250, 6.9idi, t-19, two batteries. I just bought a new battery for another car, turns out some wiring is fried, so poor thing will be headed for the trade in at a dealer...question: Am I looking for trouble if I take that brand new 750CCA battery out and install it in the truck along with the battery that is already in there...a 3 year old 850 CCAs...haven't measured the tray yet.... Both batteries in truck are working just fine....just don't want to see that new one go to waste...

not really a wise idea (not saying you can't get away with it)

here I searched it for you https://www.google.com/search?q=chan...+a+dual+system

this is the basic issue.........
"So unless they are in the same condition / same capacity / same state of charge, they won't be in an ideal charging situation because they are being treated (by the alternator/regulator) as one big battery instead of the two (or more) separate batteries that they really are."
