Well I was just curious about people that have used the agm sealed batteries. Whether you feel they are better and worth the extra cost. Also about the longevity vs regular deep cycle batteries. I s...

"Better" depends on how you intend to discharge and charge your batteries....
- What loads will you be operating and for how long?
- What is your daily power budget?
- How much total battery capacity do you want?
- How will you be charging and maintaining your battery?
- What is your budget (in dollars)?
It is my opinion that most RV owners are best served by (pairs of) 6V golf cart batteries. They are economical, long-lasting, offer tremendous capacity, very tolerant of abuse (if simple maintenance is done), and easy to charge.
I have 3 Odyssey (EnerSys) PC2150 AGM's in my camper and I think that they are amazing !!! But I also have some unique power needs, plenty of solar, and a high-current, programable charger. For me they are "(much) better and (well) worth the cost".
With regard to the Diehard Platinum (EnerSys) VS. Energizer (Johnson Controls) AGM batteries... The answer will depend upon your definition of better?
- The Diehard has higher capacity, more cranking power, lower internal resistance, true deep-cycle design, longer warranty, nationwide availability, and are manufactured in the USA.
- The Energizer is less expensive.
Both require special charging considerations to achieve their full capacity and service life.
Optima batteries were good once upon a time. But when Johnson moved their manufacturing outside the USA the quality went down considerably. Today they are among the worst choices for an RV house battery.
