It's on the passenger side at the back, between the shock tower and the firewall. You have to remove the duct to get to it. On top of the battery there are 4 numbers. The first 2 numbers represent the week, the last 2 are the year. So, if you see '2608', it would be the 26th week of 2008. Just keep in mind that is the date when the battery was manufactured, not when it was installed. This is the location for the AUX battery, which I hope is the battery you mean!
