I have a 2002 996/911 , lately I have been driving the car a lot more than I have in the past (I only have 24K on the odometer ) Point is, on several occasions whilst out and about I come back to the parked car,and the battery sounds very weak when I crank the motor,or has failed to start at all, requiring me to jump start it. Now, this is not just,a battery issue, I have had several Dura last batteries in this vehicle over the last few years (From Auto zone) Even when I have used the car on a regular basis, with a new battery in it, drove about 60 miles on the highway at 70 mph + get to my destination,and it still cranks weak, or dies on me,on the 2 nd try ! It's really frustrating, and I have to keep a Porsche brand battery tender connected to the car most of the time,as this let down happens often, even after it has been hooked up to the tender,it lets me start it initially in the garage, and sounds strong,but after I get to my destination, park it and come back a little later it's weak or fails ! A friend of mine had a 2000 996/911 and had the same problem if he left the car sitting over a week it wouldn't start. It frustrated him so much he sold it and bought an M-5. He told me the electronics in a Porsche are running all the time so that makes the battery weak ? I love my 911,but as I said,this happens all to often, with new batteries, with regular daily use, even with the tender attached,which I do most of the time. Please, can anyone advise , HELP !!! :help:
