My flooded batteries are toast in the trailer.
I have been buying AGM starting batteries for boat and truck and like them. No maintenance and no corrosion.

Thinking of going to two. 6 Volt AGM batteries for the trailer.
Would this be a good choice?
How do they handle freezing temperatures?

Fully charged wet and AGM batteries won’t freeze. Watch your prices. Two good AGMs will be close to one Lithium battery.

I think you are better off staying with flooded lead acid batteries. Two (or four) 6volt golf cart batteries. They are half the cost and I get 6 or 7 years out of mine before I replace them.

I asked 2 questions but have 1 more.
Are they compatible with any “converter”?

I have AGM batteries for my engines and house batteries. I have been quite pleased with them. For me, the lack of maintenance needs is worth it to me.

They work with any converter. Your only consideration is battery size - make sure they will fit in your battery compartment.

I replaced my 4 12V Flooded with 4 6V AGMs 3 years ago this July and not crawling into the front battery compartment to check and add water is worth every extra penny the AGMs cost. I went with Trojan T105 @ 230 AH.

AGM batteries are lead acid chemistry....just like wet cells. Should be OK with your converter, but you did not tell us what your converter is. Modern converters usually have a switching setting for wet cells or AGM. AGM batteries have a slightly different bulk charge/absorb charge requirement than wet cells.

The converter is a WFCO 55 amp. I’m sure it’s original In a 2009 Cedar Creek.
Seems to me this converter will not start to even charge if the temps are really low.
