I'm pretty sure the batteries need replacing but to be sure I need some numbers first.
Batteries read 12.6V. While the engine's cranking, the amps through the positive cables read about 390 A at most. I've heard somewhere that the CCAs need to at least be the size of the engine and diesels need more. I'm not even reaching my 6.9's 420 so I'm kinda worried. The batteries are supposed to have 625 ccas and 725 ccas at 0 degrees, I think. The 625 is a 3 year old Diehard Gold and the 750 is an Autocraft Silver bought last July. They're both charging and I'll give it another shot when they're ready.
Does this sound like they need to be replaced?

), and might look seriously into redoing the cables (as I kick myself for not swapping battery cables before I sold my old van) as well...
