Super durable and a lot of power for both starting and powering electronic components

Seem to be a well built battery, I installed three in my boat. Manufactured by Eastern Penn, so hoping they last as long as my Dekka batteries did. Cannot beat the price anywhere!

Bought four of these for my boat--two trolling motor, two house/starting. Easy install. Now I don't have to crawl into my console to check fluid levels. I have only had them tow weeks, but so far so good.

Greatbuy

I have several Duracell AGM group 31 , 27 and 24 . They work very well even 7 years later. Use a high amp Smart Charger and don't drain the battery dead . I have had some of these last me 10 years. All that being said converting to PO4 Lithium is much better in the long run.

I have two of these in my boat running an 80lb 24v trolling motor. I've used them since early in the year. We fish Lake Taneycomo (the tailwaters of Tablerock dam). Several 6 hr trips I've had to fight current with the trolling motor running constantly and averaging maybe 40% of full power. This has nowhere near drained these batteries. They recharge very quickly with my onboard charger. I'm very pleased with them and expect them to last several years.

Just replaced 2 Duracell group 31 AGM Batteries on my boat the manufacturers date code was D3 on both batteries April 2013. 1 of the old batteries is still holding 12.28 volts and 480 MCA , the other sadly is only 10.56 volts and 0 MCA. These batteries were maintained with a MinnKota 3 bank on board charger designed for AGM Batteries. I wish they had lasted longer but they did outlast every other battery I have tried, 7 years is a long time with all the electronics I use on my boat.

Last year I modified my truck camper to hold 4 of these. I dry camp on the beach in NJ and these provide the power I need for a long weekend. Remember AGM batteries really shouldn't be discharged more then 50% so remember to calculate that in your total amp usage. They are also heavy so factor that in as well. I was rebuilding the side of my camper so I just framed it accordingly. I upgraded my converter/charger to a 3 stage type with an AGM setting. I also have a honda 3000iu generator with me and 15 gal of gas so I'm pretty much ready for anything.

I bought these batteries for my RV and was pleased with the price. They were recommended by another owner, but It will be quite awhile before I can develop a history and concur. Time and performance will tell. Still, the buying experience was very good.

Recently built a new vessel, commercially shopped around for batteries, wound up getting these from Sam's! I am using 3 sets of them linked in series for 24VDC and 2 for 12V auxiliary engine starting. Highly reccommended. Hint: These batteries need the new style battery chargers that will not overcharge them.
