I've searched all over & haven't found a battery size chart or cross reference for a battery that will fit my 855. Does anyone know the proper size or model # for an Exide-Interstate or other brand. I only need 650 CCA. I think JD is a 475 CCA standard battery. I'm not sure I want a Walmart brand. Don't know what they have or the quality. Also, JD makes no sense to buy from them & pay a big mark up when they do not make batteries. Thanks for the help.
