What did you do with/to your Boxster today?

Well the battery in my car is now 10 years old. It is an Interstate H7 85 month warranty battery. Whenever my car is in the garage it is connected to a CTEK 3300 maintainer. As my car was in the shop for over 8 months due to my engine rebuild saga, and I figured that I was going to need a new battery, but the shop said no, it was still good. Got my car home 2 weeks ago and the CTEK maintainer had the green light on and the yellow light blinking fast, couldn't get just the solid green light. This is with the cigarette lighter attachment for the CTEK. The CTEK manual says when there is a solid green light and blinking orange light, it is either due to a bad connection or the battery can no longer be de-sulfated. The car starts right up, the batttery cranks the starter without any hesitation., but since the battery is now 10 years old I figured it must be the latter, that it now has sulfate crystals too big to de-sulfate. Before going out to buy a new battery, I thought I would try attaching the CTEK wires that bolt directly to the battery terminals to rule out a bad connection. To my surprise I've had a solid green light without a blinking orange light for a couple of days now. So I am putting off a new battery for a little longer, but I have my eye on the Bosch AGM H7 battery at Pep Boys as it looks like the best deal around right now at $150.
