Battery question

[Bosstweed]

I have a 2017, DRV 39DBRS3. I want to replace the batteries and since I’m a novice on this I’m not sure what I should replace them with. It looks like I have 2 batteries in tandem, I believe they are each 6 volts since each has 3 caps for fluid. Any help and or suggestions would be greatly appreciated. Thanks

From my posts a few months ago: https://www.5thwheelforums.com/forum...ight=batteries
I ended up buying two at Costco. Price was fair.

Sam's club is we're I got mine. Comparable to the ones at Costco. I added two more because of the solar panels I installed on the roof.

We also shop Sam's Club and have found all their battery prices to be fair.

Carefully mark all lines before taking any off--suggest a picture with smartphone first. Cover all cable endings to keep from inadvertent touching to metal parts. Use this time to clean and repaint the battery tray.
