Battery problems in 93 90CS

["Adams, Daniel" <adamsd@mmsmtp.ColumbiaSC.NCR.COM>]

The recent posting about the battery drain on a S4 Quattro made me curious 
if anyone else had the same battery problems I had.  When my car was 18 
months old my battery died.  It was towed and the battery replaced under 
warranty.  About a month ago (18 months later) I noticed that the battery 
was slow in turning the motor over.  It died one night and I got a jump 
start (not under warranty).  I drove 5 miles and it died while I was idling. 
 I jumped it again and it died after driving 50 feet.  I had AAA tow it to 
my dealer and they checked the charging system and said it was the battery. 
 Since the battery (Autobahn 72month/650amp) was 18 months old.  The 
pro-rate was $22 of the $109!! replacement.

Has any other V-6 owner experienced the same problem?  I wonder if this is a 
battery quality issue or some unforeseen electrical problem.  BTW, my 
previous daily driver to the Audi was a 89 325is that I traded in 1995 with 
the original battery (Varta) still running strong.  FWIW, I traded the BMW 
on a C280 which has a Varta.
