the car running, your alternator is working fine.
I would disconnect the battery, charge it, measure it disconnected, let it sit for 24hrs, measure it again. That removes any issue of parasitic draws from the car. As others say, it would be good to load test it also.
If the battery doesn't measure at least 12.7V after a full charge and being left sitting overnight, it is the battery at fault. From your description so far, I'd bet a donut that it is the battery.
I agree that jumpstarting and charging a failing battery with the alternator is not a great idea other than in a side of the road breakdown (what AAA is for - hence their advice)...
(now once you solve that, maybe you can help me solve my 11.9V battery voltage in my c900 with the car running and 0.03V drop B+ to D+... on the new alternator I just put in with no voltage drops anywhere in the wiring, belts new and good, and even the charging lamp seems to work!! I'm baffled. This condition drains the battery in about 30 minutes of driving - not charging.)
