Some Optimas have relatively low CCA, depends which colour it is. I want to say Yellow tops are higher CCA but don't quote me on that.
In any case Optimas aren't what they used to be. They completely hanged their production when they were bought out some years ago now - and I don't mean changed it for the better.
