You can conserve battery power by switching to LED interior lighting if you haven't done it already. The old bulbs can eat a lot of power.

I got 2 Duracell 6V batteries and cases at Batteries Plus. 10% off if you order on-line & pickup in the store.
I converted our old trailer to LED lighting, the new one already had it. The only incandescent bulb I replaced was the stove hood light.
Another 12V draw is the defroster strip around the fridge door. On my Dometic I could turn it off, not so on the Norcold.

So how are you not satisfied with your existing battery setup? Does the battery die before the 3 days are up?

We routinely camp in non-electric campsites, and with careful use of power (similar to what you posted - lights used sparingly, refrig on propane, and using water pump), we easily last 3-4 days camping, with battery power left over.

Are you sure something else isn't draining your battery? or... as happened to us early in our "camping career", daughter was playing the CD stereo in the camper all day while we were gone... lol!

Otherwise, sounds like the 6v batteries are the way to go.

We are actually thinking of getting a small generator this year. We find ourselves going to non-electric campgrounds / parks more and more as time goes on.


Our current setup lasts less than 24 hours with the fridge, on demand water pump, and minimal lights. I think we were given a bum battery by the dealer when we originally purchased. It tested fine but we’ve had nothing but issues.
Maybe it is parasitic draw? Or something else? I’m not too handy with electrical. Is there an easy way to troubleshoot this?

My recommendation is the 2 6V set up as it gives you the most flexability. However, if your TT is a newer one that has LED lighting and you do not need the furnace 3 nights is not a problem if you use a Group 31 deep cycle battery.


The 2 x 6v setup sounds nice, but we only use it once a year. My TT is a 2016 and does have LED lights. We definitely don’t need the furnace on battery. Do you have a recommendation on a good Group 31?

If I went with the 2 6v is there anything else that needs to be done to accommodate other than wiring them in tandem?

You need one additional wire to hook the 6 volts in series. Icing on the cake but not required are 2 new 6 volt battery boxes and POSSIBLY a new charger.

Link to a battery cable
And a strap to make adding and removing the 6 volts a heck of a lot easier.

You mentioned the fridge, water pump and lights. If that is all the power draw that you are aware of then yes the battery should last a few days and you have something else drawing down the power. If however you are also running the furnace then that is your big draw. Typically people figure one night of furnace for one battery. So if you have two batteries you should get two nights of furnace. Of course the real determining factor in battery longevity is how warm you set the furnace at night. If it's set for 73 degrees your going to drain the battery a lot faster than if it was set to 63 degrees.

If your trailer is a 2016 there's a decent chance you already have a 3 stage charger. Did you get any paperwork with the trailer, maybe an owners manual for the power center with all the fuses and circuit breakers in it? that will probably give at least a model number that we can look up to help you out.

As far as troubleshooting your battery draw. The easiest way is with a digital multimeter. Even a cheap one $7.99 from harbor Freight (free with the right coupon) will help. If you have or can borrow a meter we can help you use it.

And here's a link to a recent battery discussion which has diagrams for hooking up 6 and 12 volt batteries. Link

Thanks for the links, I’ll check them out.
Correct, there will be no furnace use on battery power.
I’ll check when I get home later on the paper work for the power center. If not, where would I find the charger? I’m not sure what/where they are usually located? I’d like to put eyes on it to verify the model number if that’s possible.

It might be built into the back of the fuse panel. On mine I can remove the drawer right above the fuses and look down inside the cabinet. There might even be a model number on the front under the fuses.

If you're not running the furnace then something is definitely dragging your battery down prematurely. Check if there is an antenna booster button behind the TV. make sure it is turned off when not in use.

See if you can also get a make and model off the refrigerator, there might be a label inside the door. Some refrigerators have a heated strip on the door that pulls a lot of power.

Maybe visit the trailer while it's dark outside and open all the compartments both outside and in. See if there is a light that got left on that is drawing power.
If you have an inverter make sure it is turned off when not in use.

If your frame will handle two 6v batteries end to end, here is the battery box you would use.

We run twin group 27 when dry camping. We run TV and video every night and furnace including all you mentioned. We are good for three nights max.



Costco group 27's are about $80 each
