Hmmm. I got 10 years out of a pair of Diehards in my F250 Powerstroke. So I put 2 more in 2 years ago. So far so good.
I was confident in buying that battery. It was for my V-8 truck and I got what I thought was a very good battery. Cost a lot. Then one day it was dead as a doornail. I had it tested and confirmed it was unable to hold a charge. Sears gave not one sh*t that it was a bad battery. I paid over $200 for it. From the Sears I got it at, to every person I could reach at Sears by phone, no one cared and they were rude. I said I’d never set foot in their store again after buying their tools for 50 years. No one cared one bit to lose a life long customer. Fraudulent fake warranties didn’t concern them either. I should have involved the consumer protection bureau but didn’t have time-I just needed a battery that worked and went to my Chevy dealer I knew for 25 years. They said Sears batteries are over priced. Can get better for less at a dealer or car part store.
