Re: Battery CCA\'s?
One problem I've had over the years is the plates busting loose inside the battery due to the Jeep bouncing around and it shorting out. The best battery I ever had for longevity was a Delco SA (Special Applications). The "Optima Guys" will tell you one big advantage of a gel filled battery is that they can't be hurt by vibration as easily.
