Best battery they sell,the spiral-grid gell cell type,lasted me 2 and a half years!Made by Exide and cost $225 taxes in .I figured I'd get the best for my Jeep ,see's a little off-roading,so I bought this battery in 2007 May.It's comes with a great warranty 3 years replacement then 10 years pro-rated.I tried to get my money back but a new battery was all the guy could do.Interstate just got a new customer
