New 6 volt AGM Batteries

Now after 3 seasons I've replaced my original 24 group 12 volt battery with 2-6 volt AGM (Duracell Platinum) 409 Ah. I'm setting up to do some off-grid camping now that I've gotten used to the full-hookup variety.

My trailer sits in my driveway, and given our cold winters I have taken the battery out each year and put in my basement when the weather gets real cold. I was wondering if this is necessary with AGM's?

I can keep my trailer hooked up 24/7 so the batteries stay topped off.

  • If your converter doesn't overcharge them, it's ok. For me, I'd rather keep them comfy inside. They're just too darn expensive to take any risk with.

    No. And it wasn't necessary with the other ones either.
    A fully charged wet cell battery doesn't freeze until about -70 F.
