I guess I should throw my $0.02 in on these.
I have had 2. One came in the escape and one came in my 2006 Mazda 6i. It was odd how they both died.
Purchased Escape new in April of 2007. Battery died August of 2012.
Purchased new in April of 2006. Battery died August of 2011.
It was almost the exact same number of weeks that the two lasted.
