Car won't start after 2 weeks sleep. WTF?

Hadn't moved the car for 2 weeks exactly. Battery is 6 months new, Bosch, fully topped-up on slow charger 3-4 weeks ago.

 

Tick-tick-tick-tick nada.

Measured the battery terminals 11.4V, no wonder. The alarm was playing games as I was trying to start it up, so I suspected that the booger (UK-spec) had drained it, then thought that the car was being stolen as the voltage dropped below par.

 

After a 24hour recharge everything is back to normal, but WHY did it happen?

The car is in the garage FFS, not even outdoors. I don't even have the alarm explicitly armed either.

The alternator works fine (14.4V on idle) so that's not at fault either.

 

 

Is the UKSpec alarm draining the juice so liberally, or is it the SAFCII? Can't think of anything else....:shrug:

 

Any ideas?
