I just drained my battery :( (archive)

The complete automotive resource for buyers, sellers, and owners like you.

oh, I did it. I drove a friend home, and we talked "just a few more minutes"
in the car, so I stopped the engine but let the ignition in position 2 so
ventilation and radio remained on. When I finally wanted to leave (the
few minutes summed up to about 2 hours) my baby wouldn't start. Battery(s)
empty. Had to push it quite a few metres to bring it in a position where
we could start it with his car as a helper (man why has this thing to be
THAT heavy :), then I drove home about an hour, hope that recharged the
batterys enough for normal operation. But as I'm also driving many
short distances, I'd feel better to recharge the batteries to full.

So my main question: I never did this on the 8, can I easily remove
each of the two batterys and load it using a normal recharger? Can I
do it in a way that one battery always remains in the car so I don't
lose any of the settings? Are the batterys just attached parallel so it
doesn't matter which one I take out first or is there a main and a secondary
battery? BTW: I had to unlock the BC again (Test 19), but all the other
values of the BC (like average fuel consumption) remained. Could there
be anything else wrong now? And the BC said "check motor oil" when I
arrived at home. As it was deep in the night I didn't check so far,
but it could well be time (a few weeks ago I checked and was down to
20% or something), could it also be that this is an effect of lost
information in the BC?

And the other question: what do I have two batterys for if things like
this can still happen? :> I thought that was arranged somehow in a way
that it's impossible to use up all the energy using just vent and radio and
so on?

Thanx & (:ul8er, r@y (feeling a bit bad now for doing that to his baby :)
