At rest, with nothing turned on, ten minutes after a 20 mile drive, the battery puts out 12.01 V at the terminals. Sounds weak to me. But, in its defense I did kill it this morning and have to jump it. It has been driven about 50 miles since the jump. What do you folks think?

I have a 2, 10 or 15 amp charger that I could put it on overnight and see what I have in the morning. Would that be a reasonable route to take? This is not an AGM, its a standard (Interstate) lead acid. Electricity is not my gig, so I need some input!
