Best deal for batteries and great warranty. Bought mine from Walmart in 2017 for my RV and it lasted for 6 years! It would still start my RV if I trickle charged it too! And yes I live in my RV and use it all the time!

Purchased 3 years ago & still going strong! 850 CA REALLY spins over my Corvette well, a lot better than the other brand I had.

Using it for my 23 year old truck and it starts great with this new battery. The price was the best I could find, too.

I have Purchase numerous Duracell batteries. They are long lasting and a good value for the money.

Great service

64 months of service means it started my vehicle at least 8000 times (@ 4 per day); I'd say that's pretty good. To max the life of any wet type car battery, you've got to aim for 100% charged at all times. Not being 100% charged aids/speeds sulfation which kills the battery. If my vehicle is going to sit for more than 24rs, I connect a battery maintainer. And, no matter what, at least least once a week I connect the maintainer when I'm done for the day. That's the secret folks. The battery in my vehicle before this one, a DieHard Gold from 2005, lasted 10 years and it too was on a maintainer. Buy a good quality maintainer, use it, and you'll get the longest life possible from the battery.

I'm giving it four stars only because I haven't had it all that long yet. I bought one in May of 2015 and as of March 2017 I haven't had a problem. I also found one was in a used car I bought and it's from 2013 and still works so I don't understand the one star reviews. I'm right now thinking of buying another for one of my other cars.

Purchased my first battery on about 3/20, 11/20 had to be replaced because it had dead cells. 12/20. Already needs replaced again. Puts my granddaughter at risk if she can't count on her car to start. Hope this is the last time. Will try to get Sam's to replace with another brand. We will see how that goes

Clearly, this battery isn't made by Duracell, but is licensing the name in order to disguise what is actually a very poor battery. I've had this less than two years, and during the onset of winter 2016/2017 this thing has been struggling to crank a V6, and it's actually larger CCA than the OEM battery. But I see that others have also had trouble with this battery. I'd suggest to Sam's that they find another supplier for this, as I'm going to take it back today and get something else - not from Sam's if it is this brand again.

I always thought that Duracell would be a great battery. but I had bought my first one 2 years ago and after 12 months it was dead and not taking a charge. Replaced it under the 3 yrs war. and now 1 year later the replacement is no good now also. I have 2 other family members also bought the same battery size and type and they also same problem battery only lasting for 12-15 months then needs replacement. sad to say think it is time to get refund for lack of satisfaction and buy different brand batteries
