I have an Odyssey battery in the Spec Boxster. Much lighter weight than a regular battery. I never use a trickle charger or battery maintainer and the car always starts right up even after sitting for a month. Its about a year old so I am not sure of the life but so far I'd say that its a winner.

For everyday driving, I have a regular AutoZone battery in my 996. No reason to spend more for the lighter weight in a street car and it gets driven regularly so I don't have to worry about how long it will keep a charge. Affordable and easy to find/buy.
