    We are taking our 2014 Forest River Evo out for the first time in what feels like an eternity, in reality about 2 years. The battery we've been using is the same one that came with it from the dealer back in late 2013, A centennial DP24MFS
    https://www.centennialbatteries.com...ose-battery-dp24mfs-group-24-maintenance-free

    It seems like its on the tail end of its life, last time we dry camped it would discharge quite quickly, so its time for a new one.

    Whenever we dry camp, i always bring one or two of our 2kw inverter generators, so i'm not worried about trying to make it a week in the woods without having to fire up the generator, but i also dont want to have to run the generator every few hours to make sure we can watch a movie at night.
    I've read about two 6v golf cart batteries is a good option. Not sure if its overkill for me. I could get a larger single lead acid or Agm. I'm not sure if i need a special charger for the agm or if the onboard charger is good to go.
    Thoughts?

    Looks like sams club has $20 off batteries for another day or two

    Function before sparkle.
    Two 6v are a very common option. For most travel trailers it’s a better solution than a single higher quality 12 volt and takes to repeated drain/charge cycles well.

    Added hitch weight (probably close to 150 lbs with two 6v) is one of the biggest down sides along with no power of one batter suddenly dies. But the pro is generally higher combined amp hours compared to a single deep cycle 12v.

    I'm not a battery expert, but the deep cell that came with my trailer lasted 3 years. During that time it would last approx 2-3 days powering the fridge circuit, heat circuit and various lighting only. (dry camping) Since then I have switched to two regular group 24 batteries. They easily last 7-10 days before I have to fire up the portable generator to recharge them. I'm going on 2 years with these two regular car batteries.

    Depends on how much money and work you want to invest in it. Here in Arizona no battery last much more that 2-3 years at the most. My trailer came with 2 group 24s that I would get about 12-16 months out of. I looked into AGM and lithium but the prices and related changes to the system just wasn't worth it. I upgraded to 2 group 27 deep cycles from Autozone and just expect to have to replace them every couple of years.

    It is what it is, but the same thing goes for car batteries here too. Just find the best deal with the best warranty and expect to replace every 2-3 years.

    I have a 100 amp hour Mighty Max. I went for this battery based on numerous online reviews, I've only used it a couple times because of the Pandemic but I'm very happy with it's performance. September 2020, I had a remote wilderness 10 day elk hunt, which it performed flawlessly, granted I was careful not to use too much power daily.

    The trailer batteries seem to take a beating since you don’t use them for a while then hit them with constant drain and charge for a few weeks a year. I buy the cheap marine grade batteries from Napa auto parts and they last a few years. If you get lead acid batteries make sure you check the fluid and top them off when you need as well as disconnect/ tend them when they h e long periods of inactivity. When camping I run the generator for about 2 hours a day. Generally when the wife of getting ready to make sure she has outlet power for her accessories. At that time we charge devices as well. That seems to be enough to keep us going most days. That’s on longer trips where we park for a week or two at a time. Usually we camp during winter so the heater is running a lot as well as the fact that she needs to shower everyday so we end up using a lot of power daily.

    Our trailer came with one small lead acid battery. I replaced it with a pair of 12V, 75 AH AGM batteries wired together to give me 150 amp hours. This was cheaper than going for lithium ion and I think cheaper than 6V.

    Haven't tested the duration yet but I think it would last us a while. Here is a link to the ones I got:
    https://www.amazon.com/gp/product/B07SY72T1M/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8

    and the wires to wire them together:

    I ended up getting a single agm over dual 6v'ers, figured that it's got a better chance of living for a few years as long as it stored fully charged.

    In my Rpod I installed two 24 group from Walmart, it was around $200 for both, I used them for about four years and they were still keeping a full charge when I traded in that camper. I added a kill switch to disconnect them during storage. I did this almost two years ago with my Shafta, did not use the camper for over a year and they still had plenty of juice to run all the lights and appliances.

    I discovered that the stereo in my travel trailer has blacklighting and a clock that stays on 24/7 if the battery is connected. It will definitely drain a weaker battery in storage. We installed a new battery and went on a 5 day trip back in Dec. After we returned I disconnected the negative cable and connected the solar maintainer. These work very well for keeping the battery topped off. I was actually there today and its still good to go.
