Not only did my "Die Hard" battery die within a year and a half of purchase, but the service department side-stepped the warranty by claiming that battery was still good; they said the car had some kind of electrical problem that they were not equipped to troubleshoot. Of course, when I went to the car dealer, they showed me that the battery was not able to hold a charge. After installing a new battery from the car dealer, the electrical problem magically disappeared.
I had successfully purchased die-hard batteries for many, many years, and am now extremely disappointed to see that Sears has dropped the ball on one of their flagship products, and has chosen to scam customers by dropping service, as well.
