what kind of batteries do i have?

i am attaching a parkit360 trailer dolly to my TT and the battery hookup differs depending on whether I have 6 or 12 volt batteries. i have two of them. how do I tell?

  • If you haven’t done anything to your newish RV, 99% theyre 12V. You should look at them. They say right on the battery.
    Even If you do have 6V in series, you still have a 12V system.
  • If the batteries have vent/filler caps, a 6 volt will have 3 caps and a 12 volt will have 6 caps.
