I suggest at least a few camping trips before investing in more batteries or charging systems. What you have might be fine.

When we first bought our TT, I immediately started looking at gas generators and/or solar. The more we camped, the more I realized we were fine with just single battery power for a 3 or 4 day weekend.

When you "dry camp" (no hookups), what will preserve your battery power is careful usage of power. Try to use as little power from the camper battery as possible. Basically pretend you are tent camping in a hard sided tent. Lots of threads in this forum with ideas on power conservation.

If you are really going to be doing a lot of week long plus dry camping or boondocking, then you will need more power.

Most RVs are sold with a similar group 24 hybrid battery. They also do just fine for most owners because they always camp with hook ups.

Whether or not this battery works well for you depends on your use. You didn't say how you will be camping.



We are looking forward to trying sites with little to no services. I guess I minimally will look into another battery to run in parallel....


If this is a new or nearly new battery, the most cost efficient option is to add another identical or similar battery. People that drycamp more than two days at a time usually find that a single battery isn't enough.

Batteries used together should be of similar age and design to prevent one battery discharging the other.

You described me to a tee! Thanks!

  • Another battery in parallel

Just keep in mind that with any battery selection how you're going to properly maintain that battery bank is also critically important, keeping in mind that often that converter / charger as installed by the trailer manufacturer is inadequate for the task at hand. [emoticon] One example would be those Duracell AGMs suggested by another poster which require temperature compensated charging which almost no stock trailer converter will do. Some batteries require bulk charging at 14.4 volts, others at 14.8 volts which many converter chargers won't do. Some manufacturers warn against equalizing their AGM batteries, others say you can and should. In other words it's critically important you match the batteries you intend to invest in with a charging system that meets the charging requirements for those batteries. For a single flooded battery which may have been supplied by the dealer and on which you only rely from time to time this isn't much of an issue as it can easily be replaced when the time comes at moderate cost but once you decide to put substantial investment into a bank of batteries, particularly more costly AGMs, plus a genset, and/or solar, you really only want to do that once you have a more complete understanding of the issues involved in properly drawing down and recharging those batteries. Unfortunately some, perhaps even many, regard solar as getting something for nothing but the reality is solar can only produce maximum results when the panels are fully exposed to the sun, so unless you're out in the desert somewhere all the time there will be plenty of times when it's going to do you little to no good at all. A genset can solve this issue for you BUT the reality is there are often restricted times at which you may be allowed to run it, and if those times don't match your schedule you may well still be left with a depleted battery bank. The point? - there really is no simple "one size fits all" solution to running days or weeks on battery power alone ... jump in too soon without understanding all that is involved and you're sure to regret it.

Advantage that they are sealed, never need water added..True maintenance Free... Made By Deka Battery...Same Specs as the Deka 31ADTM... Only difference is the warranty, but a lot less in dollars...These are Marine Deep cycle...


Thanks so much! Will check out these options.


ysidive; they are Absorbed Glass Mat(AGM), not AMG.

richardtc17; I have used AGM batteries since 2009.

Duracell AGM Deep Cycle Marine and RV Battery - Group Size 31 aka; DEKA Intimidator Group 31 that is relabeled for SamsClub.

Whew! Incredibly, valuable information. We are going to act as if we are dry camping this weekend. Our form of a field test.

Thanks so much!

And here in Canada these East Penn / Deka batteries are labelled as RV Care Traveler's Choice but are the exact same batteries. Note the instructions for properly charging these AGM batteries ...

So will the converter in the camper properly charge a deep cycle 29 or does it require a separate quality charger?

Depends on the charger, it's characteristics, and whether it's been properly installed, which often isn't the case as trailer manufacturers usually just stick the converter wherever it will fit and at best use 6 gauge cable for the run to the battery regardless of how far it may be located from the converter. Adequate for those who rarely dry camp, a nightmare for those who do dry camp regularly and expect the most out of their deep cycle battery investment. In my own trailer my WFCO 8955 converter which is well known to rarely bulk charge at 14.4 volts is mounted at the far rear of the trailer with ~ 25' of 6 gauge used to get to the battery. It never delivers a 14.4 volt bulk charge so I've permanently turned it off and instead use a portable charger located with feet of the battery to properly charge the battery. This charger doesn't offer temperature compensation but my current flooded battery doesn't require it ... if I were to upgrade to one of these East Penn / Deka / Duracell AGM batteries I'd want to also upgrade the charger to one that does offer temperature compensation. Unfortunately that eliminates most converters as most, with just a couple of exceptions, don't offer TC. Some pundits here on the forum disagree TC charging is necessary but it's clear from the pic I posted above that East Penn doesn't agree, insisting their AGM batteries do require temperature compensated charging. Guess who I believe? [emoticon]

Does anyone know why temp comp is important enough to be printed on the label?
