E30: Battery Drain

["Tony Lin" <tonyplin@xxxxxxxxx>]

Hi Folks-

Can anyone suggest some possible reasons for a slow drain of current from my
battery when the car is off?  Clock?  Those silly idiot lights and their
rechargeable batteries?

It's a brand new battery in the car- I just replaced a 1yr-old one which was
under warranty.  Apparently the old battery drained down to nothing after
the car was parked without driving for periods of a few weeks.  The new
one's  showing a 14hr overnight drop from 12.2v to 11.8v.  At this rate, 3-4
days of not driving will drop the battery to below cranking voltage.  I
can't think that it's just another bad battery.
