Had it for over 3 years now in a Chevy Tahoe, still cranking like it's new. I've even abused it a couple times now by letting it get discharged so much my car wouldn't start because I left my dashcam plugged in for too many days. Put it on my charger and was working fine after. Will be buying another one whenever this one dies.

I put 2 of these in my 1996 6.5l Diesel Suburban. It's been a long time since this Diesel has cranked and started so fast. This is one of the few batteries that has both top and side mount posts. With my present set-up I need to use both the top and side mounts in order to connect 2 batteries.

This was my first Duracell AGM. I have always bought Optima. Duracell had a 34RAGM for a reasonable price - it was $100 cheaper the Optima. Decided to give the Duracell a try so I bought a Duracell 34/78 RAGM in December 2017 for my 2011 Toyota Venza and it went bad in June 2018. Soon as it got warm, the battery started draining overnight (Disconnected the battery and it dropped 20% by itself in 12 hours). There wasn't a replacement RAGM within a 100-mile radius of Sams Club. Sams gave me 100% refund - great customer service. Bought an Optima RedTop and it starts stronger and no problem.

I bought this battery and it lasted just over a year and a half and completely died. I took it back to Sams Club as it had a 3 year free replacement warranty. They tested it and told me it tested good and they could not replace it. I went to a second reputable battery dealer and had them test it. It tested BAD, 28% and said "Replace battery". I went back to a flooded cell Interstate, as I got over 6 years out of the last one of them and it was still going strong. Interstate also has a better warranty and stands behind their product. I would NOT but this product again.

I put this battery in my 2000 Chrysler 300M which called for a group size 34. I sat a 34 and this battery side by side on the store floor and they were almost exactly the same. (One was about 1/8 inch taller.) I've had it installed for about a year and have had no problems with it. It's 175 CCA more powerful than the OEM battery required. It's an AGM battery, so it's also totally sealed. Thus, it should not cause terminal corrosion - which is important to me since 300M batteries are replaced through the right tire wheel well! This battery was the best value on the market when I bought it at $99. It's still an excellent deal at $119.

Like another reviewer, I installed this battery in a Chrysler. My install was a 2009 minivan that had an OEM very generic looking Group 34 battery. Despite being a Group 78 battery this Duracell fit the battery tray and engaged all the hold downs properly. No reservations. Battery power is good so far. For an AGM battery, there are other options, but it is hard to beat the value this battery represents. Look around and you will see some AGM batteries with better warranties, but you will pay a lot more. We'll see how well the battery performs over time, but initial impressions are very good. As always, the help at my local Sam's Club was very good.

The C5 Corvette is fussy about what battery is used. It's a computer with wheels and any power drain can cause bumps in the road. This battery has worked flawlessly for the last year. It fit perfectly, and if this ever gets tired I'll replace with the same. AGM is the only way to go to eliminate any chance of acid leak.

I've purchased several of this model battery for two different vehicles an '81 GMC High Sierra and a 2007 Silverado both are loaded with options. The average life for them has been seven years in each vehicle. I do use desulfators when the vehicles are sitting unused. When they die, they tend to let you know by a slower than normal cranking. When that happens, it's time to get a new one. With seven years of life, I won't complain. The only battery I've found that will last better is the Odyssey. At twice the cost of the Duracell AGM, they will last twice as long with the same care. That's not bad at all for either as, pricewise over time, the cost works out the same.

Died in less than 12 months. Warranty is for replacement with exact same battery but Sams never has it in stock and won’t order it so can’t get it replaced. Free replacement only good if Sams stocks battery. This is exact same battery as Super Start Platinum which I had to buy to replace battery(was on sale for less than Sams)

Started having weird starting issues. One day it would be dead, then get a jump and it would last 4 weeks with no issues then dead. Jump start, driving 10 miles and it would only crank 3 seconds then dead. No draw on vehicle and alternator works properly.
