Sorry for bringing up an old post but this is great information.
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....
