A couple of things to check. If you have access to a voltmeter:
With car sitting overnight, your battery should read around 12.76 Volts in the morning with the vehicle off
After start up your voltage should be 13.5 V or greater. Anything less than that, your alternator isn't charging.
If you don't have access to a voltmeter, turn vehicle off, remove key,pop your hood, and unplug your light if you have a lighted hood. Pop your battery cable loose and then put it back on. If you have any large sparks, this indicates that something may be running with the key off. This may be dangerous though.
