These are all 12V Deep Cycle Batteries, not Marine STARTING Batteries. The Group 27 battery I found at O'Reilly's and the Group 31 at NAPA.
I'm not finding a true deep cycle battery on O'Reilly's website. What model number are you considering?

Keep in mind an AGM may require a different charge profile than a flooded lead acid. You want to match your battery to your charger or vice versa.

On Edit: You might consider a 150Ah Trojan T-1275 true deep cycle battery as a compromise to two 6V GC2. There's a better chance of it being a drop in replacement for your existing battery. It can be heavily discharged the same as the GC2 in a smaller footprint of two GC2s. Just another option to consider.

Call your local golf cart dealer for pricing if interested. Shipping can be expensive if you buy them online. Maybe he can order yours with a larger battery order to minimize shipping.

Based on my usage of a size 24 deep cycle lead battery, if temps are in the 20's, you'll get about 12 hrs running just the heater fan per battery. 3 size 24's got me on par typical use as 2 size 31's. I prefer the two 31 option. BUT as noted by one poster, carrying a 31 is too much. But they can carry a 24, so the three 24's if they fit in or on the battery tray, would be the better option for that person.
On the other hand, if wieght is really an issue, like is is for some water/land yachts, I saw that a size 24 lithium battery has about the same usable AHr as an 8d battery which is 3-4x heavier. Or about equal to 3 size 31's.
At the end of the day, choose your poison, the only best/worst way is how you use your rig etc.

Why do the batteries need to be carried? Just leave them in place year round.

I believe the person saying carrying the batteries ment for him even exchanging them. Some of us can not, nor should leave them in an RV during times of non use. Ie a storage lot, no 110 to trickle charge the batteries during say 6 months of non use. That's an 18-20+% discharge. So best to keep at home where it's warmer, and you can setup a trickle charger.

The NAPA battery is a NAPA Specialty/Golf Car GC12 650 Deep Cycle Part Number 8141.Amp hrs 150 AH.

Warmer is the exact opposite of what is good for lead acid cells.

Fully charge and disconnect.

Or add a modest solar panel system. 5 watts per 100 amp-hours without a controller and a nominal 12 volt panel.

For me, carrying it means getting it in and out of the battery well in my basement. I'm stooped over in an awkward position with my arms extended to get my hands on it. It's all arm muscle and hard on my back to lift it up and out of the well and basement. Think of it as my battery is in a 6" deep hole inside the cloths dryer. I have to get half my body in there, reach in and lift it straight up 6" to get if out.

Checking the water is impossible when it's installed.

Thanks, this helps.

The 27DCM is a Johnson Controls hybrid battery identical to the Wal-Mart 27DC I use. Same battery rebranded. I've had real good luck with these.

The NAPA is the East Penn equivalent to the Trojan T1275 I mentioned above. This guy is a beast that should last you many years if you take care if it. You can get 3X the Ah out of this between charges compared to the 27DC.
Make sure it fits where you are going to mount it. It's too tall for my battery compartment by 2". Plus it weighs 85lbs. See my whiny story above.

I ended up with a Group 31 Super Start Deep Cycle from O'Reilly. I checked into the Group 27 from NAPA and was not available. There was a question if there 31 class would fit. I can also purchase 2 Superstart 31 for 1 NAPA.

There are filler kits available.

I would certainly leave batteries in place. Just as I have "caged" the generator.
