Looking for a battery for the IROC, machine has to crank 10 or 12 revs to start usually. Getting cold out and the old Diehard is five years old now. Went to Sears, Diehard is 90 bucks or 115 for the Diehard gold. I've always bought Diehards but that is getting out of hand pricewise. Looking at A-zone's Duralast Gold or the Advance Autocraft Gold. Both about the same price and rating. Anyone have experience with either? Any comments good or bad? Either made in USA?
