Bought battery for trolling motor, seemed to work fine. Hard to tell how much actual capacity, but used trolling motor for 5-6 hours.

My old batter was on its way out and the Duracell battery perked up my motor above what I expected!

I purchased 3 with the rebate, very happy with the product.

I needed 4 of these batteries for myRV they worked great.

Purchased to upgrade batteries on my camper since we camp without power hookup. This battery has been great thus far.

Have had 2 of these installed on my camper going on 4 years. They have been fantastic, they stay installed all winter while the camper is plugged in with no issues. 100 watt solar panel when camping with no concerns whatsoever, always have plenty of power. the furnace blower can go all weekend without concerns of batteries getting to low even when cloudy out. recommend these, for the price they can't be beat!!

I have 20 of these installed since January 2019 on an off grid cabin. 7 years of constant use later they have lost only 35% of their capacity. I power a 8k BTU AC in the summer just fine. 3.2kw solar charging MAKE SURE YOU TREAT THEM RIGHT BY NOT DISCHARGING BELOW 50% AND KEEP THEM FILLED WITH DISTILLED WATER.

Heavy built batteries

I purchased these batteries about 2 years ago for my jon boat. I ran 2 of them together for my newer model 24v Minn kota trolling motor that has a digital maximizer. They performed great the first year then things started going down hill. Unfortunately they only lasted 2 seasons of bass fishing here in Pennsylvania. I took very good care of these batteries all things considered. I have a pro mariner onboard charger which conditions and charges the batteries that is plugged in 24/7. I also made sure to take the batteries out of the boat in October both years to sit in a temp controlled environment during the winter while still plugged in to the pro mariner conditioner/charger. I did everything by the book and these pieces of junk still didn’t last 2 seasons! And to boot, there were several days after being on the water for about 6 hours they were noticeably drained already and my trolling motor would lose power so I can’t say these are up to par with the claimed amp hour rating. I was just out this past weekend and was nearly stranded because the batteries are now absolutely toast and have no life left when it seemed like they did the previous trip. I’m very disappointed because the cheaper everstart group 29 deep cycles from Walmart perform better than these. I am talking specifically about the group 31 Duracell deep cycles in this review. Great price but poor quality. I have a group 24 Duracell deep cycle as my cranking battery that also runs a 12v tiller trolling motor for extra power and it has been working flawlessly for 3 years now. I would stay away from these group 31s choose another brand. For some reason it seems like the group 24 has way less issues.

I bought this battery April 14th of 2019. Mfg date was February of 2019. I used the battery for my trolling motor one time that summer. The rest of the time the battery kept on a maintainer until this year. My trolling motor showed full charge but no power. Had it tested at two auto parts store and was told it had dead cells. Sams club confirmed this but of course it has a 12 month replacement warranty. The same club person told me these batteries have a lot of this issue and not to purchase another one. Don’t waste your money on this trash. There is no savings buying from Sam’s for this size battery. Just get a reputable battery from somewhere else. If you are set on buying one make sure to get yourself a load tester and check it monthly to ensure if or when it goes down you know. Mine still shows a 12v charge but is gone.
