So far so good for our RV!

So far so good! These replaced the two wet cell batteries for our 24' RV. Easy to install and so far so good on performance!

Great battery

Lots of juice, keeps my bass boat’s large electronics and livewell running all day long, and reliably cranks the engine to bring me back to the dock.

Sulfate not good

I bought 5 of these a couple years ago. Quit taking charge, removed cap (Maintenace free) most cell had no water. Sulfate covered tops of most cells. Caps are difficult to remove!

Great choice for marine battery

Finished my third season for these on my 30 foot boat. Used as starting battery and house battery. I keep the boat on shore power with a charger going all summer. Performed flawlessly so far. Recommended for the price.

Worked when new, but failed quickly

They worked great when new...after a year both have failed to hold a charge. I took the leaking one back to Sam's, they refunded the cost quickly. I didn't realize the other one was also losing charge until today. I need to take it back as well. When new, I was able to go for three days running a 12V fridge, the lights, and the water pump. When we went camping last week, I had to charge the battery every day to keep the fridge running. The voltage has dropped from a full charge to 9.9 with a solar panel connected. It's losing charge faster than the solar can replenish it in full sun with nothing running. Replacing with a 6V in series and hoping for better longevity.

Best price by far

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

Great batteries

Just came off a weeklong fishing trip bought 3 for my 36V trolling motor before I left, charged them up never charged them all week and used them a lot for spot lock and trolling on my Nitro ZV18 boat.
