i'm in the market for a new battery for my 6th gen sedan (4 cyl) and came across these die-hard batteries. i think i'm gonna go with die-hard instead of optima batteries because they provide more cold cranking amps for like $30-$40 less than optimas. plus look at this new "security" battery they now have with a built in kill switch. i'm not sure how good it is but it sure seems very interesting. does anyone have this installed?
