I had gone to batteries plus and bought a nice 120 A/h deep cycle for $100. It was a Group 34 Xtreme IIRC. Then my brother showed up with a massive 8D-MHD from Interstate that he thought was going to fit into his boat. It didn't. That was a $220 battery. He offered a trade and I reluctantly went with it.
The Xtreme weighed about 60 lbs IIRC, the 8D-MHD weighs 132 lbs.
As close as I can figure with the 8D-MHD, it has over 180 A/h (I think the math is right, 450 minutes at 25 Amps)
I would rather have 2 of the Xtreme's, and that is likely what I replace this one with when it comes time for that. 2 of them weighs less than 1 of the 8D-MHD's. Fortunately I'm a big guy and can move the the big battery by myself, I would still rather move 2 - 60lb batteries.
The whole thing works well though. For my limited use of 12v over the last camping trip, that battery ran a Fantastic Fan on 50% and various intermittent lights for 3 days without trouble. I plugged in the generator after that for a recharge, although I have no idea if I needed it. No battery monitor yet.
