I was running a TLE a couple years ago when a guy came in with a truck battery that he wanted to return. I told him that three things kept me from approving the return. 1 You don't have the receipt, 2 That battery is at least three years old (at this point he pointed to the five year warranty sign on the battery rack) AND 3, That is a Duralast battery from Autozone and security is on the way.
