Battery Question
I recently bought a 01' 2500 CTD, 175,000 miles
I parked it for a week, a cold snap came through, down to about 40f (I know, that's not cold compared to up north)
When I started it, it cranked slowly but fired okay, next morning, same. I checked the battery, 12.3V before starting ing cold. The glow plugs drew it down to 10.8V before I started it, after it started the alt. did the job fine up to 14.2.
Question: Does the 10.8V draw down, and the slow crank mean the batteries have reached the end of they're lives?

nope, the draw you see is the grid heaters. there like a toaster coils in your intake. this is why you never use starting fluid on a cummins (unless you unplug the grids).
they will crank slower in the cold.

Your batt. should hold a better charge the 12.3 after sitting over night. 40* is not that cold to really strain a batt. Take the battery and have it load tested. It will save you alot of problems when you need it and it wont start.
