Thanks ManiacGT. I guess disconnecting the battery is out of the question if I can't lock the boot. Any idea how many months a good condition battery will last before it's depleted?

If the battery is totally dead, where are the connectors in the hood? Will it short out or blow some fuses with a jump start?

The other alternative is to connect a trickle charger to a 220V UPS backup battery in the trunk and hopefully that will give the car battery a few extra months of juice via trickle charging. I might go this route if all else fails. Just have to figure out what UPS size battery I need to extend the car battery for 6 months since I live half a year overseas.

My car is still under factory warranty so will BMW replace a damage battery from deep discharge?

Thanks again for your post!
