Alarm Issue connected to Low Battery ?

My neighbour's 993 has been sitting idle for about 4 weeks, so perhaps unsurprisingly, the battery was flat. However, when unlocking the car, the alarm started, and could not be stopped even when locking / unlocking the car.

Once we connected my battery charger, the alarm did stop.

After getting the battery mostly, but not completely charged, we disconnected the charger, and tried to start the car. It did turn over but did not fire and you could hear the battery flattening quickly during this process.

The nett effect....the alarm kicked off again !

Anyway, car back on charge, and will remain so all night now (to stop the alarm apart from anythinng else !).

My question is - would the flat battery have any link to the alarm being triggered, or is this purely coincidental ?
 
Yes it will ... and the fact it wasnt firing could be due to the immobilier NOT fully deactivated...sounds like the battery could have already gone to the great battery playground in the sky..
 
This is such a pain in the butt, especially when it happens during the early hours and you are lying in bed trying to decide if it is your car or someone elses that is waking everyone up! It once took me a good 5 minutes waiting for the battery charger to put enough juice in the battery to properly disarm the car.

I no longer leave the charger off for more than 2 weeks as, in this cold weather, charge can disappear sooner than you think.
