A class batteries

A class Dolphin 535. I have 3 batteries,, Replaced the 1 for the engine ,,, guessing ,, lol ,,, Have 2 other batteries next to it .. Figuring its for the 12v system. Replacement for Interstate U2300 Battery states 6v. wish i could post a picture ... The cost for 1 batt. is $175.00 ... Just want to make sure its a 6v ... Yes I checked the labels and didnt see 6 or 12 ...
  • Look at the number of caps on the top of the battery. Usually 2V per cap..

    3 caps is 6V

    a U2300 is a real HD 6 volt and there expensive;; much better quality and amperage and warranty than costco
    however they should be available for much less than $175 Iam thinking in the 145$ range new number is GC2-XHD-UTL
    If your going to do any amount of boon docking buy these ones over the cheapo Costco ones
  • Make sure when you take them out you know how they are hooked up and which wires are going to the Pos and Neg posts. Take a picture and make a diagram.

    On the other hand if you normally camp with shore power you don't really need the best batteries. Two cheaper 6v or even 2 12v batteries may meet your needs, depends on how you use them.

    yes why I said ""If your going to do any amount of boon docking ""
  • I would suggest getting red tape for the positive and use black tape on the negative wires.
