[csx4910]

While O'reilly's and auto zone carry optima batteries, this particular part number doesnt come up even as a special order. I hadn't though of Summit or other internet companies as I prefer to buy local but will look up the part today. Wondering if becuase it is almost 5 years old if the part numbers have changed for their 6 volt now. Existing part number 8010-044 and Summit's only 6 volt option is part number 9010-044. Direct replacement with new part number perhaps?
