Can anyone point me to where I can order a new OEM battery? I plan to do the install and registering myself (using the enthusiast kit listed here)

I'm trying to avoid the dealer at all costs. Pretty pissed off at the moment because I just bought the extended maintenance for an ungodly amount of money only to have my battery fail 2 weeks later and not be covered by it. My car is telling me my battery is dieing and the dealer wants to charge me $120 to tell me the same thing....

As long as you get the same size and cold cranking amps you can use any brand of battery. Just register it once installed. I've had a NAPA battery in my car for a year with no problems. Also be sure to hook up the vent tube to the new battery so it doesn't catch fire in the trunk.
