I have a 2005 Cayenne S and my battery crapped out on me.
What is the best replacement battery for my Porsche Cayenne S?

OEM Porsche, Optima, Odyssey, and Interstate were the 4 batteries I was recommended.

I would go with a Optima Yellow Top battery. It has never let me down!
Same here. I've run both Optima red top and yellow top. They also come with a free replacement warranty for three years. I would buy those over OEM Porsche batteries.
