    There are some possibly inaccurate and definitely confusing statements in the reply you got, but the first part, that agm is a physical structure of the lead acid battery that can be tipped over without making a giant mess and that deep cycle is another function of design as opposed to a function of the lead acid chemistry is correct.

    What’s left unsaid is that lead acid batteries which are damaged and not working right anymore have a much safer and lower tech recycling process than lithium ones do and that’s saying something because one of the parts is lead!

      Thanks! The other reply obviously meant well but was a bit mansplainey !

      My situation is, I’ve recently purchased a camper trailer. It’s wired up but needs a battery. I haven’t had time to “research” other than seeing what batteries people are selling second hand. It seemed to me that everyone was using AGM batteries for this purpose and while I knew that AGM referred to the physical structure of glass mesh I had assumed it was synonymous with deep cycle batteries.

      Now I’ve read about it a bit more I realise that LiFePO4 batteries are superior but more costly.

      I guess, the reason why I was seeing AGM batteries everywhere is because everyone’s buys them because they’re cheap and then realises they really needed LiFePO4 so they try to sell the AGM and upgrade.

        I’m a wet cell lead acid man myself.

        There’s the monthly battery fluid level check to contend with but if you can make sure it doesn’t tip over too often or too long and you can bank on being able to get to civilization once every six or ten years then you’re in the low total cost of ownership ecosystem.

        Of course, they’re not as good in the cold and if you screw up and let all the water leak out then you gotta fill it back up and hope it’s not too messed up.

        Whatever you pick will be fine. Tbh if you’re not gonna have the trailer for longer than the life of the battery, pick the one that’s got more curb appeal or resale value!

          Fair enough.

          It seems like on an e-bike Lithium would be the go due to it’s higher energy density.

          On a trailer you can house it in something appropriate and the size and weight requirements aren’t as restrictive.

          It seems like keeping the battery is a common practice when selling a trailer. That’s why mine doesn’t have one. A lot of people would never use one if they’re always parked in someone’s yard or in a powered site.

          I doubt we will really need a battery at all over the next 6 months with the trips we have planned. Probably better to hold off until we have a few trips under our belt to determine exactly what appliances we’re really going to need.
