And finally, where is the battery in the E60? In my old E46, SL55, etc the battery has been in the trunk but a quick look and I couldnt find the battery. After a glance I couldnt even spot the battery in the owners manual....where could it be?

Battery is in the luggage compartment. Raise the floor mat. Undo the screw of the right side panel. You have now access to the fuses and the battery. (Well, at least for an european 525i, but I haven't seen any exception in the manual).
Edit: Sorry 53r Sport. Didn't see your much better explanation...

Nope.
Yes.
The power is monitored, and when the system recognizes that there is a leak/loss, then all systems will be shut down by the computer to preserve enough power for one more start, so that you can drive away and visit the dealer.
That's one of the reasons the car wakes up from its sleep mode sometimes, to measure everything.
Of course it will die! One thing is that the car tries to preserve energy, and it's true that ALMOST ALL systems will be shut down (legally prescribed systems like hazard warning lights and side lights are never disconnected), but even with this, the battery level can drop and it will not be able to supply enough energy to make the engine start. (Battery can be defective or reached its end of life).
It may even occurs that the car sent a warning measure during the night, but nobody was there to see it...
I received this message some days ago, when I was using a electric inflator connected to the lighter.

Eh?
Every battery will die eventually.
Nope.

All the systems that will NOT be shut down don't use enough power to drain the battery to a level where you're not able to start the engine, since evereything else will be shut down waaaay earlier.

IF the battery is defective, then YES, but only then.

Defective battery is probably the case - I can't understand how someone who drives 200 miles with a presumably functioning alternator can then have a working 80/90 Ah battery drained the morning after!

Those "legally prescribed auxiliary consumers" are switched on by the driver, so he knows about. They don't need much power, what means it takes HOURS to drain the battery to a level an engine start is not possible anymore.
