Battery is good, dead cold voltage after sitting overnight is 12.55v

Does the Boxster have the same problem?

I had a car that experienced this same problem, ended up being a worn out starter.
The windings in the motor seem to weaken when hot..

I would check all the obvious first, you can get you battery load tested to see if the batteries failing.
I went through all that stuff first..
