battery problem on 996
Discussion
I have just bought a second hand 996 c4. I have had it for about 5 weeks now and it has been totally amazing (my first porker). It has only been driven at weekends (too busy during the week ). I tried to start it today but the battery was totally dead!! I tried jump starting it using the connections in the engine bay, but it would not turn over (although I did get power back into the dash).
I know that it has a lot of electrics etc, but surely the battery should not drain that quickly when the car is not being used. Anyone have any suggestions?

I wouldn't worry too much, its probably just the battery thats given up and needs replacing.
If the car has been allowed to flatten its battery completely then it never really recovers and the charge will leak away with very little effort.
The classic example being cars which have spent two weeks in long term parking at Gatwick, the alarm goes off every time a plane takes off for the first few days and then the battery goes completely flat. You get back off your holiday, get a jump start and think all is well until you leave the car for a few days and it won't turn over.
All modern lead/acid cells suffer from this problem unless you buy one of the clever deep cycle batteries which are designed to go totally flat on a regular basis.
My 993 needed a new battery two weeks after it was delivered as the previous owner had pretty much left it in a garage for two years.
I have had no problems since changing the battey and suspect you won't either.
If you are going to lay the car up, an Optimate Charger is well handy and keeps the battery in tip top condition.
Good Luck,

I've been told it's a common problem with 996s and boxters. I also remember reading something in the letters page of 911 world too. It's a problem with the official Porsche batteries when they get too low in charge they fail (dead cell or something). I went through two Porsche batteries before replacing it with a suitable BOSH. No problems since (touch-wood).

I think the battery is new. It looks it anyway. It is not the porsche battery! If the battery is good, how long should it stay charged before dying like this?
It has had a tracker and a hands free fitted. I will have these checked out first. I have bought a battery charger, so hopefully it will be running again soon.
