I have a question about replacement batteries. My 911 is driven everyday (my 4th year in this car, 2 other previous Porsche's) here in Michigan where it's about 10F today. My drive commute to work is about 6 miles so it's about the worst driving circumstances for the car. Anyway, about 2 years ago my battery died so Porsche replaced it and the same symptoms started appearing again, 'whirring long before the start'. I know I'm up for another battery so I checked online at Sears and enter: 08, 911, 3.6L, exact -> no find, optional matches -> no find. Where are you guys finding batteries or are there any recommendations?

BTW, my 997 has a battery charger built-in so you just have to plug it in... I also have a Schumacker (sp) charger and that works as well...

Autozone sells 'em. Have one in my '07 C4S and it works great. Has the proper terminals and vent tube.
