  • OT: RV Battery

    I am using my RV here in the Iowa winter. I need a battery that doesn't quit. It's nice to have heat and light when the power goes off.

    I have had the original and two replacements and all have failed after a year or two. Can't remember all the brands but one was an Interstate.

    Are there any brands of RV service batteries that will last for the guarantee period?

    There are a lot of good batteries out there.
    I get 3 + years for 2 batteries in my RV. I don't hold them till they die. I dry camp in cold weather and when they do not hold up for 2 nights of furnace running, I dump them.( Last ones were from Sam's Club, and before that I had Champions.)
    It sounds to me like your builtin battery charger is overcharging and burning out the batts..how often do you need water?
    If less than 6 months, its over charge in my opion

      more likely, the battery charger is undercharging the batteries. Check the charging and after-charging voltage. If the charging voltage isn't over 12.6 volts the batteries will never be fully charged. With the charging finished, get rid of the surface charge and the batteries should be at 12.6 volts.

        I have been Rving for more years than I want to remember, the last two Rv's I have used two 6 volt golf cart batteries hooked in parallel. works much better and your charge
        lasts longer.
        Cost is just a bit more for the heavy duty 6volt
        ymmv

          I installed a battery disconnect and have not had any battery problems for the last five years. JRouche

          Dont forget, you can switch either the positive or the negative, does not have to be the positive lead. I switch the negative for my hotrod because I didnt have room at the positive side.

            make sure you put your SporTrac in neutral when you tow it.

              Standard RV converters are diabolical: They don't have a high-enough voltage output to charge the battery in any decent time frame, nor to even get it fully charged. Conversely, the voltage is too high for constant charging when the system isn't really being used.

              Change the converter to one of those 3-stage jobs like the Inteli-Power with Charge Wizard and you'll get much better usage from your batteries. Also, change the batteries to a pair of Golf Cart units.

              Another thing that's nice is something like the eMeter from Cruising Equipment. You wouldn't want to run your car w/o a fuel guage, but most everyone lacks a proper "fuel guage" for their RV batteries.

                Thanks for all the responses. I just figured out that it might work a lot better with some water in it. It took a gallon +.

                My bad. I shall hide my head in shame for forty years.

                  Be sure to use distilled water to refill your battery.

                  Regular tap water has minerals disolved in it and can cause what is called "local action."
                  This causes the battery to self discharge internally with no apparent load.

                    Yeah, you wouldn't want any 'local action'. The whole idea of an RV is to GET AWAY.

                    I seldom do anything within the scope of logical reason and calculated cost/benefit, etc- I'm following my passion-
