Your car has a battery drain that discharges your battery when the car is off. Look for things that have been left on like trunk lights or other obscure items. If there isn't anything obvious, connect a volt meter between the positive batter post and the positive battery cable and start pulling fuses until the voltage goes to zero - that is the circuit you will need to diagnose to find out what is drawing the current and draining your battery.
Test for a parasitic draw.
