Re: OT: Battery or alternator
If the alternator is working you should have approx. 14.5 volts DC at your battery when the vehicle is running. If 14.5 volts is present - your alternator is charging your battery. If the battery has less than that you have an alternator problem. You can check this with a volt meter set on DC with the red lead on the positive terminal and the black lead on the negative terminal.

Re: OT: Battery or alternator
If the problem is in the Durango the charger has to feed it and the battery, I would disconnect it and charge it to see if it charges better. If it does charge OK you will also get a nice little when you go to hook up the cables. At any rate it should be a dealer thing!

If I remember right, you should see 12.3-12.7 at battery with engine off. Running it should be around 13.5-13.7. 14.5 seems high.
