[BiturboS4] 2nd Battery in 6 mos.

[California Fields]

[ Converted text/html to text/plain ]

I, too, left my S4 undriven for about 2.5 weeks over the Christmas/New YEar's
holiday and it started up just fine when I returned. Haven't had a  battery
problem in the 6 months that I"ve owned the car.  Granted, it doesn't get
below 45 degrees here in San Fran, but I don't think temp is the issue.
