Sounds like a parasitic draw. You will need to install an ampmeter in series with the battery to determine how much draw you may have. Disconnect the negative cable and install one end of the meter tom the cable and the other to the battery and take a reading. There should be no more than 250 milli volts or 1/4 amp draw. If anything above, the battery will drain down. You will then need to start pulling fuses to see if the reading drops. If it does, then whatever is on that fuse will be causing the drain and diagnostics will commence from there. Make sure there are no interior lights on or devices plugged in to any power supplies first. The vehicle will always have a draw to some extent as it constantly keeps power supply to memories and modules but should be no more than the 250 milli amps
