This is the very same battery that is sold by Marine supply stores for a little over $300. The manufacturer is the same but sold under a different brand.

I installed 3 of these to run my 36v Minkota Ulterra on my Walleye boat, 3 years ago. I’m very impressed with the performance and value, especially compared to Optima! 5 stars! Capt Jim BALZER, DoubleJay Sportfishing

Very satisfied with this battery! Using it to power my audio system and it delivers!

I sold the camper but wanted a good AGM. This one is. Happy with Sams club and East Penn.

Purchased 2 for my RV. Worked great the first few months then would not accept a full charge after 9 months. Returned for a full refund and then purchased 2 more. If these don't perform, I'll return and go with another brand. I've used other brands of AGM baterries in my RV and boat for almost 15 years and have had a couple of AGM batteries last over 10 years. Thank goodness for the 18 month warranty.

I purchased 4 of these to use in my motorhome. $800 worth of batteries. The coach did not even get used. I installed the batteries 13 months ago in my motor home as starting batteries. The coach was never on the road and was only in storage with a trickle charge on the batteries the whole time. One month after the 1 year warranty expired they are shot. Sams will do nothing about it. I am going to do a youtube video and post it later.

Has been functioning A-OK for 20 months as the backup sump pump battery for the BullDog Sump Pump System that takes over when we lose power (which is happening more and more often.) Replaced as preventative maintenance for our notably smaller lead-acid battery that waterproofing contractors installed with the BullDog. After initial full charge I unlpugged the AC and let the BullDog System run on the battery without recharging down to 12.2 volts and this battery's rated capacity appears fairly accurate though IMO a bit optimistic.

we use 24 of these for solar power to house, can turn whole house for 3 days no sun and if grid is down. charged with solar panels all the time.

I've been running deep cycle Group 31 AGM Duracell's for 3 years and the starting battery for a year. I'll never go back to a wet cell battery.

Bought 2 if these batteries to replace 1 and add another to our 5 wheel RV. Great price, will follow up later on how well they do!
