Maintenance free battery for backup sump system

Worked great and maintenance free for my backup Wayne Sump Pump system.

Great value, reasonable life.

I'm replacing a set I installed on my 36V trolling motor back in 2019. I'm not sure why so many people had problems, but AGM batteries are sensitive to being overcharged. My on-board charger has circuitry to avoid that sort of thing. Or maybe I just got lucky? Regardless, I'm going back with the same thing.

Decent - Lasted 4 years for my Sump Pump

Hoped for 5 years, but lasted a little over 4 years before sudden failure. Pretty good. Thankfully my sump pump alerted me the battery died.

I got a pair of these for my boat and they have been great so far (about a year). Taking star off because they never have them in stock and required calling around and multiple trips to get them.

Duracell AGM Platinum marine battery

Don’t be fooled by the attractive price of this battery. As a 50 year boater, these are among the worst batteries that I have used for both cranking and house battery. Tried to return two that died roughly 6 weeks beyond the 18 month free replacement and was told that the best they could do is use them as a core for a trade-in on a new battery. What a joke. Don’t waste your time or money. Also, a little disappointed with the Sam’s personnel handled this matter

Epic Failure

I bought this in March this year. Used on my RV one time this year and battery already shot and it's warranties for 17 months. This is the second RV/Marine battery that has failed within 6 months. Either I'm very unlucky or these are garbage.
