These are quality batteries built and sold in the USA I was in the battery business for over 20 years in distribution of multiple brands these are far the best made by East Penn manufacturing. There are too many variables in electronics and batteries for someone to give a bad review on a battery. Especially when they are usually not an engineer.

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!

I own a 2001 Z28 camaro that has some anti-theft devices that draw current 24/7. It eats batteries for breakfast. This DURACELL battery held up for 34 months and Sams replaced it with no problem. Very satisfied.

Why the lousy ratings? Back in January 2011 I bought this battery for my 72" Grasshopper 928D2 mower w/28hp diesel. I mow 20 acres every week here in southwest coast of Florida. And I beat the heck out of this mower. This battery just now dropped voltage...over six years later! Going back to Sam's to pick up another.

I got mine in Dec. of 2013 and now in Nov. 2020 it is sounding a little bit hesitant when starting my 2007 Pontiac G6. I am going to buy it again.

I bought this in 2014 and it just now died. Been running my car every day will be buying the same thing.

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

MY FIRST BATTER WAS DEAD AFTER 2 1/2 YEAR. MY SECOND DEAD WAS DEAD AFTER 11 MONTH.

battery is 1 year old , dead as door nail , prior battery lasted 4 months , not very good

I bought 3 of these batteries and have had nothing but trouble with them. BEWARE
