Thanks for all the replies. The service guy just gave me a boost and could not help as far diagnostics. He didn't even know where the battery was. Anyway i ran to the store and picked a new battery and charger for the old and we will see. I hope it's not the alternator. BTW the battery I pulled out was a VW battery. Is that what they put in Porsches?

Sounds like second battery to me. The new Porsche's are shipped with a Bosch (crap) battery.

Good luck.

LOL. No, the original battery is made by a company called Moll. I guess someone drained the original, and replaced it with a VW battery. Good luck with the new battery. Make sure that with the new battery, you reconnect the vent tube, so that gasses/fluid can escape cleanly from the trunk area.

If you suspect a faulty alternator, get a good battery in there, start the engine, and check the voltage across the battery. At idle it should be around 14v. If it's 12 or less... you could have a bum alternator.

This sounds very similar to my issue. lancelot092466 - Did the changing of the battery do the trick? Please let me know if theres anything special about putting the battery in or is it an easy swap. Thanks!
