Works great with my GM car, reserve and crank power is great. Been two years since I bought the battery, my car has a long crank time and this battery never sounds as if its going to give up. Also It is an AGM so it does not release corrosive vapors like flooded batteries that would slowly rust my hood. Warranty isnt too bad for the Price but would have liked to see 4 years free replacement or some kind of pro rate after the 3 years.

I'd been fighting wet batteries for over a year. This stopped the fight!

Purchased 11/2023 required replacement 05/2024. While at Sam's Club getting replaced. 2 others came in to get their Duracell Platinum AGM's replaced. Looking around while waiting. We saw a cart in the corner tire area, with nothing but used Duracell Platinum AGM batteries on it. Makes you wonder if that was a good decision buying this high end battery. I will say, Sam's club replaced mine at no charge. That is a good thing

Listen to the rest of the people here - I'm sure the battery might be fine as a whole but Sams sold a complete dud. Took it home and it has little to no voltage, go back to Sams to easily swap it and was told we can't do that and my only choice is to fork over another $200. I can't stress this enough, I would 100% recommend not buying from here.
