Batteries..

[mikesz]

thinking about going with an optima. A lot of talk about the odessy batteries but when i look they are for motorcycles? these are much lighter than stock. Can anyone enlighten me on which one they are using for their boxster? I dont drive mine in the winter, I live in RI. Its basically a summer car used for joy riding on the weekends.

These are all good lightweight choices:

Deka motorsport AGM battery- 17 lbs $89
Odyssey PC680 AGM battery- 15 lbs $114
Shorai LFX36 Lithium Iron battery- 5 lbs- $300

You will have to fabricate a solid mount or battery strap and I recommend keeping an AGM on a battery maintainer designed to work with AGM batteries if the car sits for longer than 1 week. Porsche electronics draw current even when the car is off.

If you're thinking of an Optima battery you want the Optima 34R since this reverses the battery plus and minus posts allowing it to easily connect with the Boxster setup. However, the Optima battery not as wide as the standard Porsche battery and you will have to either make or purchase an adaptor plate allowing the Optima to be secured by the mounting bolt located in the bottom of the battery tray. Great batteries though.

ok so the odyssey P680 is basically designed for motorcycles. Are there adapters so the Boxster battery clamps can clamp to this battery? Are those what the "L" adapters are for?
