OK, I do not mean to steal the thread or sound like an idiot, BUT I am curious about the statement "Optima has the lowest capacity to foot print because of their spiral cells".. Everything I have ever heard about Optima's is that it is about the spiral design that gives them more power in the smaller foot print? I have purchased Optima's and by any measurement CCA's etc. they are smaller than a similar rated traditional battery, so I am confused as to where you got your information??
