I finally got some semi nice weather to take my Cayman S to Porsche of Fairfield. I've been having problems with the car dying a lot…. like every day. I'm aware P-cars are notorious for battery issues but I think mine is draining something while its off maybe like a fuse?

So I dropped the car off yesterday to check that out and also do the 40k mile service. Anyway I'll let you guys know what happens with that, now for my question. How many of you have the battery maintainer and is it really necessary if you dd and/or drive the car often?

 

You don't need a maintainer for a car that's a DD or driven 'often'. Have you checked electrolyte levels and density?

 

Ok.. So they checked everything and even left it plugged in overnight to analyze the results and they couldn't find anything. Also when I first got the car, I put a new battery in it because the previous owner didn't drive it a lot, so I'm sure thats not the problem either. The only thing I can think is the previous owner installed a radar detector/jammer that could be running the power but they said that checks out fine as well.
