idk i've heard that optimas have gone down in quality in recent years. i can attest to this w/my red top in my explorer which lasted 3 years w/ no discharges ever and died after 3 years one morning it just wouldnt start and after being tested it was toast.

my opinion, and what i did with my last 04 V10 was went to walmart and bought the biggest battery i could get. i think it was 1500CCA and installed it. comes with a 3 year warrenty and only cost me $89 verses the $130-150 of a optima.

if you are going to go with a optima, red tops are mostly for daily drivers. yellow is for big sound systems, winches, lots of lights..ect and blue is marine.
