Sv: a/c kills battery.....help

Once I had 100 Avant. Due to wish of a pollen filter, the
batteri was moved to (under) the back seat.
>From that time and on I had problems.
Before that I could leave the car withe park light on for days!

My 200QT20V are born with the batteri under backseat. And
I have the same problems.
They found, that the ground connection from batteri to engine
was not too good.

I think the problem is, that the charge regulator is placed at the generator
don't messure the resulting voltage at the battery. The generator have
probally amp's enough but are not allowed to put them out.

You can check that using a tang ampmeter.
And check the voltage drop from generator to battery.

BTW I don't know where your battery is located
