I bought my '09 new in Sept. 2009. Replaced the battery in July 2013 as a preventive maintenance measure since my experience tells me that batteries usually fail around 48 months with little to no warning. It was an Interstate brand with a 60 month warranty. Guess what ? It failed without warning a couple of weeks ago after 38 months of service. I bought another, and even with the pro-rating of the remaining warranty it still cost me $100. Good thing the battery was dead when I tried to start it to go to work in the morning and I wasn't stranded somewhere. My insurance covers roadside assistance and a guy was there to give me a jump in 20 minutes. I figured a 60 month battery should be good for at least 48 worry free months but it failed and I always made sure it was topped up with distilled water. The Optima batteries look nice but don't have a good reputation. Buy a good battery and swap it between 36-48 months no matter what the warranty and you'll have peace of mind.
