In Oct 2000, Sears installed a Die-Hard in my '64, and over the week-end it had to be jump started and recharged. When I drove back to Sears I full expected them to charge me for a diagnosis and if the old battery was defective to pro-rate the cost of a replacement since it was warranted for 2 years. In fact, they replaced the battery at no cost. Too bad it took me almost 78 years to realize where to buy car batteries! I certainly recommend Sears for your next battery. Frank
