Yes, they are. And you can mount them upside down if you want. Try that with your "wets". [emoticon]

24dc is the group, not the voltage. I know, I'd never heard of it either.

Lol that's what the 24dc meant.[emoticon] I was assuming the OP wanted to wire in series for 24 volts.

Guess what happens if you forget to recharge them to 0.5a/100AH at 14.x volts until amps taper that low. (see that guide and the other brands' guides, same thing.) You need an ammeter and a charger that will hold 14.x volts for as long as needed to get that done, which many chargers/converters can't do.

Also AGMs can be mounted sideways but not upside down.

Again, thanks for all replies.

Group 29DC at Walmart for $100.00 each with 2 YEAR FREE REPLACEMENT and a pair in parallel will fit.

p.s. -- not too concerned about being WET since if I roll the MH pretty sure other issue will arise.

Lighten up a little. [emoticon]
And please, stop micromanaging other people's batteries. It helps no one.
How do you know they can't be mounted upside down? Have you ever tried it? [emoticon]

I would think so. [emoticon]

Scroll down to where it says, "Except upside down"

Also read para 3.9 here, which even says if on their sides, only the long way, not up-ended.

With a battery history of neglect, I suggest you buy an AGM battery.


Winnebago 2101DS TT & 2020 Chevy Silverado 1500 LTZ Z71, 300 watts solar-parallel & MPPT, Trojan T-125s. TALL pole for flags. Prefer USFS, COE, BLM, NPS, TVA, USF&WS, state & county camps. Bicyclist! 14 year Army vet - 11B40 then 11A - (MOS 1542 & 1560)

OP A single 12V battery will do the job based on no dry camping, about 80Ah depending upon the group. 2x the power for 2. Plus easy to remove and charge if needed. [emoticon]

If in the future you want more power and longer life then consider 6V deep cycle battteries. Larger, heavier and cost more. [emoticon]

IMO, if you hook up two 12 volt batteries in parallel, when new and roughly factory equivalent, they will mimic each other. As you charge/discharge them, one battery will tend to do more of the work and take more of the wear over time because of the way they are wired and their inherent internal resistance. As you discharge/recharge them, one battery will charge more than the other because it is working harder and sees more charge. (or less depending on which battery gets the higher charge voltage) That's why, in general, 2 simple 6 volt batteries wired in series (to make 12 volts) are normally used in simple applications. With more than 2 batteries wired in series/parallel, things can get more complicated.

Edit: That said, if you want the cheapest solution, just get a dirt cheap 12 volt automotive battery. If you don't boon dock and are always connected to shore power, IMO it's all you need.

Google: "The 12 volt side of life" if you want a more detailed explanation.
