You might want to consider a battery maintainer. You absolutely do not want to deal with the problems of a dead battery in a Cayman. For starters, you can't open the hood to charge the battery. The manual over-ride requires removal of a front wheel which you can't do because the anti-theft socket is in the trunk. Your key will not release from the ignition switch. I use a Ctek charging through the cigarette lighter.
