Battery time. 6V?

So the not so old batteries in the Camper are cooked. I pretty much knew it. One thing I didn't pay attention to and maintian the last few years. Never seen batteries so dry! Lol

Good time to switch to 6V batteries.
So standard GC batteries are a bit too tall unless I remove the sliding battery tray. I could do that, but what about the shorter flush post batteries like NPP NP6 or Mighty Max 200ah deep cycle batteries?
Little more spendy than the "bargain" 225ah GC batteries but they're AGM and I can keep the sliding tray becasue they're shorter.
Anyone use these brands?
Issues?
They appear to be quality deep cycle batteries. Maxing out on capacity, 225 ah vs 200 is not a big priority. They're all going to need charged up every day or 2 the way we camp, if Boondocking.

  • Sounds like you have problem with charger when you boiled old batteries dry?
    Start with getting better charger.
    I use car & boat batteries in my camper. When they are not deep-cycle, I never had a problem with it.
    When you buy designated batteries for camper, I would remove the try and put GC batteries. Best bang for the money and cheap batteries from Sam's lasted me 12 years, even they were not carried about much.
    Having 24V battery bank in my motorhome, I used them for welding.
    Just out of curiosity.
  • If the cost isn't a factor for you, go with a 100ah LiFePo4 battery. The same capacity at a quarter of the weight and size. It is maintenance free and has a built in battery monitor keeping your investment safe from undercharging. Although the initial investment is high, they are coming with a multi-year warranty that will protect that investment for years to come.
