I have an older craftsman lawn tractor, it has a kohler engine and I believe its 14 hp. I've tried charging it but it won't hold a charge. Anyone here ever use a lawn tractor battery from AAP? Are they any good? I can save $20 off a $5x.xx battery with a coupon code. I have not compared the cranking amps to the current battery yet but I will be sure to do that before making a purchase.
