AGM Battery recommendation

I need new batteries. They must be AGM because they will be located inside my van. I need around 200 amp hours. I'm considering this 12 volt battery for $503: crown-agm-12crv8d-12v-240-ah
Will this battery be ok or should I try and find two 6v batteries? I'm finding it hard to find decent 6 volt agms for a reasonable price locally.

Thanks.

AGMs are Valve Regulated Lead Acid(VRLA).

You can call that sealed. I have two AGMs on their side. They are sealed in the sense that they don't spill as a Flooded Lead Acid(FLA) would. There is no free liquid in an AGM. All liquid is Absorbed into the Glass Mats(AGM).

I was going to say that. They are sealed, but they have pop-off valves that will vent if internal pressure builds up. They still should be vented out of the passenger compartment. My BMW just has a little tube about the size of a soda straw.

I second the Lifeline.

There is no magic with 6v AGM batteries like the flooded style. Get what fits best to obtain the needed 200+ amp hours. I am sure Crown is fine although I have used and recommend Lifeline brand.

Well, no, but I can get the Green Bay Packers to load it. Or if they are not available, my nephew can help. He's 6'5" and young.

Might be great, but are you aware of itโ€™s large size and weight? Can you manage a 162 pound battery?

Price seems high. WindyNation's AMGs (100 ah) are $186.00 each.
