Just replaced my OEM with the Walmart Everstart MAXX-H6. Cost $99.00 plus fee and core until I brought old one back. I brought back an old lawn tractor battery in place of the XF battery and got the core back. Less than $110.00 and no problems since (got the raising spoiler and click-click once, OEM was almost 6 yrs old). No problems since and very reasonable!
