That thread about software uodate 4.6 got me thinking - the vampire drain must be a complicated problem, otherwise they would have fixed it a long time ago, right?
Apologies if I've missed earlier discussions about this aspect of it, but - given the amount of energy lost overnight, it can't simply be due to drain from electronics, or even battery heating (especially in the summer months), can it? Doesn't it have to be something in the chemistry of the battery itself? And doesn't that make it a very very tricky problem without an easy solution?
Also, I'm sure this calculation has been done elsewhere, but - during summer months, when you keep the car plugged in, approximately how much energy does it take from the charger to keep itself topped off? That's aside for any driving usage obviously.
