You need to do a parasitic draw test. Use a voltmeter to check base voltage of battery. Then crank the engine, check voltage at battery. It needs to be at least two more volts than previous base voltage. Then apply a load or turn on headlights. The voltage should not drop over one volt. Ideal base voltage at battery terminals is 12.6, ideal charging voltage would be 14.6, ideal loaded voltage would be 13.6 volts aproximately. If you find a drainage in system and you have a good battery, then you need to check radio and main accessories first, then check door latch switches and courtesy dome lamps.
