Purchased my last 3 year battery at Airpark. It was time to replace it and much to my surprise, Kyle said when Kerry bought Airpark the warranties were extended to 5 years (that alone tells you something about Kerry). Kyle prorated the extension time and gave me a Brand New 3 year Battery, for a very minimal cost. They hit a home run with that one. btw, they came out to our place, and jump started the dead battery, so that I could get there without a tow. Thanks for coming to the neighborhood Kerry!!!
