I just saw some Optima Blue tops some place recently... might have been Costco. They are rated at 750 CCA. I didn't know what the Red tops were rated for, I see someone already posted 800/980 depending on temperature. Don't remember the price on them either.
I remember several months back, someone posted they were using the Optima Yellow Tops, which I think are the Marine deep cycle batteries. Any advantage to using that type in a pickup truck?
By the way, I'm still on the factory OEM batteries, 2 years and 48050 miles so far.
