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.

Needed to replace a DieHard AGM battery that lasted almost 10 years in the AZ heat. This battery has a great rating at half the price of others. So far it’s been flawless to include heavy winching. Very happy.

I put this in my 1989 Jeep. Had to make a few adjustments but I knew that in advance since it's larger than what it called for. Needed it to keep my Jeep running and use with the winch as well.

Replaced a pair of Optimal batteries in my GMC Duramax diesel. Time will tell longevity, but so far no problems. Cost was a major consideration as these are less than half the cost of Optima's.

In my Jeep and trucks but they've gotten too proud of their name. This Duracell AGM has nearly the exact same specifications as the Optima, for about $100 less. Time will tell if it will prove as trustworthy but I expect this Duracell will prove as reliable as their batteries have always been.

Great battery for group 34. Fits like a glove for 06 Chrysler Pacifica. Would definitely recommend to others....Worth the money!

I recently purchased this battery. It worked as designed. Got it for a good cost with the instant rebay.

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.

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.

After driving two hours to have may batteries tested, I waited three and a half hours to get two batteries tested, only to be told that they were both good. The problem is that both batteries were both fully charged when I left home , and according to the battery tester it was dead and had to be charged before the could test it. So it cannot ride two hours fully charged not hooked to anything, and pass a battery test because it's discharged, but passes with with flying colors within 5 minutes of being charged, imagine that. The second battery passes according to Sam's club even though it is rated for 775 CCA and only putting out 563 CCA. Both failed when tested at a local auto parts store, and were replaced by their store brand, a little more money, but if I have an issue they won't try to bend a person over!!!
