Car locked for 5 days...dead battery. This is ridiculous BMW!

I haven't driven my x5 for 3 weeks and it started up fine yesterday (i usually haul around my daily beater). I don't think you're supposed to use battery chargers on it though, the electronics are hella sensitive on this car. The manual even says you really shouldn't jump it if it doesn't start unless you absolutely have to, and recommends you get it towed to the dealership.

If that were true, it would be rather odd that BMW sells a battery charger for it with the BMW logo.
