battery suggestions?

Just picked up a used dutchman 26f. Its my first trailer with an electric slide and I had no idea it needs 12v to operate. My battery is toast to the point it takes hours plugged in to house power to even move. What battery to you suggest thats not too expensive? I wont be going off the grid with it. ALso, I notice the lights run off of 12v while plugged in. What else does?

    The OP already said - " I wont be going off the grid with it", in which case a single garden variety Group 24 12 volt flooded marine / RV battery he can buy anywhere would serve his purposes just fine, no need for him to spend any more $$$ even if you would. :R
    I'm going to go with the oldwizard1 on this. I believe two GC2 6V's are an upgrade to a single hybrid 12V.

    Yes, the single 12V will most likely serve as a decent power source for emergency braking, using a hitch, slides, and limited lighting. Thereafter, to be connected to shore power or recharged by generator.
    However, there may be times for more 12V use or insufficient charging takes place. The pair of 6V's will offer more reserve and are much more durable than a hybrid 12V. I think some of that transfers to $$ efficiency and ROI of battery power.

    The OP should also be informed not to store his new RV with the battery connected. Some install a disconnect switch or remove a battery cable. If not, the parasitic draws of the circuit boards and alarms will draw down the battery to "dead", within about a week (depends on RV's devices and size of battery, temperatures).


    You guys!! hahah
    6v vs 12v hahah, plenty of deep cycle 12v out there. I got 2 12v, that could be considered way better than your golf cart battery hehe
    Just saying

  • A regular RV/Marine battery would be fine, the difference in cost between group 24 and 27 is literally only a couple of bucks at your local helmart, or for $20 more you can get a group 31. Personally I would go a little large because the 2 year old Group 31 will likely still have as much juice as the 24 at the beginning.

  • Don't forget the breakaway switch for braking must have 12V. A charged battery is mandatory when towing the trailer on the road.
  • Welcome to the forum!

    Any inexpensive group 27 or 31 12v RV/Marine battery will work fine if you are not going off grid.

    Things that need 12v to operate: furnace, fridge, water heater, water pump, propane detector, possibly smoke detector, exhaust fan, entertainment center, lights (as you noticed), power jack and slides if you have them.
  • Oh my. Consider reading about RV electrical. All 12 volt lights, fridge on propane and fans run on the 12 volt system plugged in or not. The difference is whether the battery is supplying the power or being charged. Of course the slide is 12 volt. How would you use it dry camping otherwise?
