I will NEVER buy another Sears Diehard ever again. The last 2 have gone bad early. The last one was 5 months and less than 1000 miles on it before it went bad. And it went bad in a really bad way. I was pulling into Ouray from Denver and I had a very strong rotten egg smell. It was the battery boiling over and spewing acid along with hydrochloric Sulfate fumes. This stuff can ignite with just a spark. I had to let the battery cool down and I headed to the nearest town with a automotive store and that was O'rileys. They ran a test on the battery and the alternator. Turned out it was a bad cell on the battery. Sure Sears would have replaced it under warranty, but guess where the nearest Sears was, 100 miles north in Grand Junction. There was no way I was going to risk having this thing boil over again so I had them throw in one of their batteries. I had the same issue with a Firebird about a 1 1/2 ago having a battery go bad with less than 1000 miles. With fewer and fewer Sears being around and stores closing more and more, I don't ever want to have to drive all over to get a battery replaced under warranty. And BTW this was a Gold AGM battery.

ok thanks for reply on that,
wasnt sure on these . i notice when dealers do a update they tend to drive different for like 100 miles or less then every thing seems normal , so i didnt know if there was that same type of effect . thanks

well replaced the stock one today
went with the ever last maxx h6 730 cca $117.98 (not to bad )
•5 Year Warranty Program (3 Years Free Replacement + 2 Years Pro Rated)
The factory one would be 4 years old next month and it was still working fine & looked like new.
but couldnt risk it anymore . Not worth getting stuck . one less thing to worry about i guess.
