Juantwo3 is an unknown quantity at this point
I had this problem as well about a year ago when the battery light is on check the voltage when the car is off and both terminals disconnected should be at 12 volts. test OK?

then put terminals back on and start the car check voltage again should be 14 volts.

if everything is ok battery is holding charge and alternator is charging then there might be an issue with the voltage regulator in the alternator. at that point just replace the alternator
