Fifthwheel batteries

I like AC Delco deep cycle batteries

I gotta say 2 6 volt golf cart batteries, too.
Even the cheap ones from Sam's Club will get you 220 amp hours. The last set I had lasted 9 years before we noticed a fall off in performance. Very few 12 volt batteries are really deep cycle no matter what they may say on the case.

Pretty sure the spell checker got him, and mean to say DEKA battery's.

Atomic or Betavoltaic?

Would you care to explain that in English?

I replaced my group 24 batteries with two Costco 6 volt golf cart batteries

Personally, I'd opt for 2 6v golf cart batteries, instead. They are =true= deep cycle, meaning they can be repeatedly be drawn down to low levels and recharged without damage. Not many 12v batteries can stand this and, of those that can, they are =expensive=. 2 6v golf cart batteries from Sam's/Costco and a cross-over cable should run you right around $200-225.

I have had no issues with the Exide or Interstate batteries we've had in the past, either will provide good service if they are properly charged and well maintained. We purchase all vehicle and RV batteries from Samsclub as they have the best prices in our area, I don't really pay attention to the label or badging since I have a multi-phase smart charging converter on our rig that will keep them very happy and performing at their peak. We leave our rig plugged in 24/7 when stored in our sideyard.

Everyone likes to buy a brand but read the specs before buying anything. Cram as many amp hours as possible into the battery compartment. Group 27 batterys are better than the stupid little group 24s the builders usually install.

If space allows, get a pair of group 31s, a single 4D, or even an 8D if there is room.

I probably should have gone with two batteries when I switched last summer. Had one new Interstate battery the came with the unit new in August. Unfortunately the factory or dealer only installed a 505mca battery which imo is puny at best and won't keep up with the large fridge with circulation fan that's always running. Also starts the onboard generator or should I say wouldn't after boondocking for about 5 hours. I found the biggest mca battery I could afford and switched them out. Happy days.
Interstate batteries are good as any but make sure they have the guts to keep you going. They do make some small ones that will still sell because their name is on the side.
