I think you need to go back to basics. Test battery voltage with the car off, and the car on. Disconnect the battery from the car and measure it, then do it again 24 hours later. Check voltage drop on the battery cables. Be sure the mechanic who tested parasitic draw knows you must wait 10 minutes before testing.
2007 9-5 100 milliamp parasitic draw on maxi fuse 2
I replaced the alternator, battery, and starter! I went to start my car this past Sunday, and nothing. 
A local mechanic discovered there is a 100mA power draw on the maxi fuse 2.
This is what they wrote up:
---
TECH
TESTED MAIN WIRING AND FUSE ROUTING. CAR HAS 100 mA POWER DRAW KEY OFF ENGINE OFF.
MAXI FUSE 2 REMOVAL RETURNED A LOWER POWER DRAW.
FUSES POWERED UNDER MAXI FUSE 2 = FUSE 1, FUSE 20, FUSE 16, FUSE 17.
REMOVINGFUSE 17 RESULTED IN FURTHER DROP OF POWER DRAW.
FUSE 17 RUNS MAIN INSTRUMENT UNIT (DASHBOARD INTEGRATED CONTROL ELECTONICS MODULE)
Cause -
DICE MODULE IS MAIN SUSPECTED CULPRIT, THEFT CONTROL MODULE AND ENGINE CONTROL MODULES ALSO SUSPECTED IF DICE MODULE PASSES DIAGNOSTICS.
CUSTOMER RECOMMENDED TO REGULARLY DRIVE CAR, UTILIZE BATTERY TENDER WHEN PARKED, OR
INSTALL BATTERY CUT OFF SWITCH.
---
Any thoughts on what it could be? Would the SID module affect this? There are no interior sounds (turn signal, open door, etc.) The trunk light is off, and I turned the interior lights off. Or is a cut-off switch my best/cheapest option?
Thanks,
Jeff
