The old Optimas were awesome. I am not a fan of the new "Mexican Made" ones, had two bite the dust on me and to be brutally honest I just dont have faith in them anymore.
Theres better options out there. Odyssey is now making the Die Hard Platnum Marine battery. The great thing is having Sears garantee and stores coast to coast, they are almost as plentifull as Wal Mart with a much better product. Much better option and only a couple of pounds heavier. 880 CCA/1050MCA vs 800CCA/1000MCA (Optima) and 49lbs for the Odyssey, 53lbs for the DieHard vs 44lbs for the Optima. More cold cranking amps, more reserve, and same price. Only a few more pounds.
DeKa is also making a spiral cell knock off through Car Quest.
