The batteries may be sulphated. There are many threads on how to deal with this.
You may have to get the voltage up to as high as 16 to rescue the batteries. If you plan this, then it is HIGHLY recommended to disconnect the battery bank from the RV. Anything over 15.4 volts may cause lots of damage to the computer boards in the RV.
The batteries have been removed from the trailer.
Could you provide me a link to a good desulphating process description ?
I have a couple 30V 5a or 10a cv/cc power supplies that I could put to use to desulphate them.
