Took it back to Advance and they would test it in my truck and it would require it to be charged inside store. The super "inside the store charger" would say fully charged and they would reinstall it. Next morning it was dead. After 3 days of this silly game I finally convinced them to test it in the truck after their "super duper, inside the store" charger pronounced it fully charged. The outside the store equipment said it needed charging inside. My size was not in stock so, they ordered a new one overnight. It arrived DRT (Dead Right There) and the manager was POed and gave me a yellow top. It is not correct for our application but, I am nursing it untill it dies! Then I will go after a Die Hard Platinum battery that is a true AGM battery with the longest warranty. Chuck another $150 into the camp fire!
