Alternator may be faulty and not charging the battery or you may have a voltage leak to ground which is discharging the battery like a clock or radio light or some other faulty electrical component leaking power.
The alternator is the easiest to check. Does the battery go flat as you drive it? If not its probably not the alternator. You could check it with a current meter when the engine is running.
You could do the same with the battery when the engine is off to see what the current drain is. This might give you an angle on the thing which is draining the battery.

Is the system charging? You should have 14.2 14.6 volts at the battery. The charge light is controlled by the alternator internally. If the charging system is working, you could have a bad diode inside the alternator keeping the light on or a short/grounded circuit to the battery light
