I really like the optima batteries for the usual reasons. if yours is the same as the one in my old SC, it's HUGE! I run a smallish optima in my SWB. it turns a 3.0 with a hi-torque starter through 45 year-old wiring easily and for extended periods. a three season car so haven't started it below freezing but everything up to that point. probably weighs a third what your stock one does. easier to use blocks to shim your existing mount to fit a smaller battery.
