997 Battery Problems
Discussion
Recently bought a gen 1 997 (circa 2006). Understood that the battery was not the original, i.e not very old.
After leaving in the garage for a couple of days I found the battery dead. Successfully recharged but a few days later the battery failed on attempting to restart the car when hot (after a run of 30 miles). On advice I bought a battery refresher from Porsche which I have been using nightly. Battery has charged successfully and car started ok each morning. Today I stalled at a roundabout (whoops!)and again refused to start - battery dead. Restarted courtesy of the AA. When I got home I left the car for 5 minutes after which it started perfectly. I then remembered that the common denominator between the times when the battery failed was that the car lights were on. Tried to start the car again with the lights on and - failed to start!
Being a bit of a novice in these affairs I would welcome advice as to whether this is a simple failed battery or could their be something more sinister at play. I can understand a battery dying overnight but not after a decent run.
Would welcome any comments.

Fantastic responses - many thanks. Symptoms identical to those detailed in the posts. Should have added that the current battery is an OEM and I've been using CTEK charger overnight.
You've taken a weight off my mind and I'll get a new battery tomorrow.
First time I've used the forum - very, very impressed.
