Well, I had my battery replaced November 2008. Today, I had it replaced FREE at Wal-Mart. I noticed yesterday the car slow to crank up, I thought it was just a spoof. Did it today, I tested the battery it was charging good, but was loosing power under load. It had like 400 cold cranking amps, the battery was supposed to have 700 with its age, or 800-900 new. I'm surprised my car started. The battery was made November 2008, an Everstart 72 month pro-rated, free 2 year replacement. I was lucky. I will have to check, its either November 2008 or December 2008 I had it replaced. I thought Everstarts were supposed to be good. Maybe a flook. I have about 60k on the battery. Wal-Mart rocks for batteries pricing and warranty. The Auto Parts store charges more, you get less, plus Everstarts look nicer.
