Anyone still have a receipt for a Mopar Battery ??

I was in the Dodge Dealer today, and to return a faulty battery they need the reciept. They said that if I could produce them with a reciept, or a copy of one from within the last 18 months, they'll honor it and get me a new battery. The battery is a MOPAR battery, and I told them that it's pretty obvious that I didn't purchase it at Walmart. Anyway, they said that I just need one with the same part number of 4709386, and it's a Mopar-60 Gold Series.


Any help will be greatly appreciated. Thanks !!!
