Go with wal-mart now that your volvo's a ford it should be a perfect fit. Buy the premium line though, I think it is yellow. I personally don't trust Sears. The best, I think, is an Interstate, but I think you can only by them from a garage. Napa premium line would be among the best as well; they would at least be able to tell you what the very best battery that would fit your car is, maybe. Remember that you don't have to go by their guide on what will fit. It is all about what size will fit in your battery pan and on what side the + & - terminals are on/you can always go taller if it doesn't hit the hood.
