2006 Bighorn 3500Rl Batteries.

[Bison]

I am a new Bighorn owner, The old owner advised me that the batteries were in need of replacement. When i looked at them it seemed to me that they were not correct. They are Marine / RV 405 CCA 505 MMA. I also onoticed that the boxes they sit in are quite a bit larger than the batteries that are in there. So before i make the purchase of new ones i iwant to make sure i get the correct ones. When ii checked with Les Schawb they advised me that there were two dif types/24's that were 550 CCA and 27's that are 675 CCA. I want to get the correct ones. Can someone tell me how to tell what belongs in the 5th wheel. Thx

Hi Bison,

Either Group 24 or Group 27 will work, but the more demand your usage puts on the batteries, the more group 27 will be the better choice.

To avoid damage, make sure you have the batteries wired correctly. Here's a link to more info on RV electrical. Battery discussion starts on page 10. There's a drawing on page 11 that shows the difference in wiring when using 12V batteries versus 6 volt batteries.
