Dead battery with no warning

[PaulE]

I've owned my '03S since new and it's only had 2 batteries - the original for the first 6 years or so and an Interstate battery since then. My car usually lives on a CTEK battery maintainer when it's not in use, but since moving in April I haven't organized the new garage yet to park inside. And now that it's in the shop with the engine disassembled, I am expecting it may also be time for a new battery when I get my car back. But I'm not complaining, I've had great luck with the Interstate and will probably buy another one when it's time.

When mine went, I could only start by jumping. I was 65 miles from home and it was dark. I jumped it, drove it home with my lights, no issues. So in my case, battery was kaput, but the alternator did the heavy lifting to keep me going for an hour and a half.
