One of the early stories was you couldn't part up a Tesla at say
the airport while you went on holiday for say 3 weeks, unless left
plugged in. Which seemed odd to me, as even a lead acid battery on
a normal car will last at least that under quiescent drain, with
all the toys.

I found that after 2 weeks near Heathrow, The electric unlocking
wouldn't work. There was barely enough charge left to turn the
engine over.

Yes - remember reading somewhere the battery in a BMW wasn't covered
by warranty if parked up for more than 3 weeks.

Of course if the battery fails, so does the alarm, so you might as well
just disconnect the battery. ;-)

It was probably the alsrma nd teh radio together which were draining the
battery

Even my 20 year old BMW has some form of can bus switching. Which almost
certainly means bits of it are consuming current when doing nothing. Even
plain old central locking has a timer circuit which will take some
current. And it all adds up.
