battery is low charge. Take it for a long drive, to take the load off the engine from the alternator charging it.
Changing an alternator isn't GENERALLY a difficult process. I'd estimate around an hour of labor - so whatever they charge per hour plus the cost of the alternator. Possibly a couple a hundred bucks.

A bad belt, a bad regulator in the alternator or bad brushes in the alternator.

You can have the alternator tested free of charge at just about any major auto parts store. By the way, a bad alternator will not "discharge" a battery - the alternator's function is to provide the charge to the battery. If the alternator is faulty, then it is not providing the charge necessary to keep other components from discharging the battery. I had the alternator tested and it was charging. If the alternator has a bad diode, it will discharge the battery. I replaced the alternator and everything is fine.
