how do u charge battery at home without plugging in

So, I have a toy hauler and it doesnt get used every week. I will normally just take the stuff out of the fridge and unplug the cord from it. As far as keeping the battery charged what is the best/easiest way to keep it charged without plugging the whole rv in. I know many keep it plugged in to run the fridge, but i will usually just do that the night before a trip. Being a 38' rv, i would need to run a long extension cord to run a trickle charger. I know the propane detector runs the battery down. So, i see 3 options:
1) extension cord and trickle charger (pain in the butt)
2) keep rv plugged in (unneccessary)
3) take battery out and charge elsewhere (bigger pain in the butt)
Or are there other options?

Thanks

IMHO the simplest solution would be leave it plugged in. We store our 38' coach in our driveway and leave it plugged in but turn converter off, as we have a 110w solar panel with a 25amp controller that keeps both chassis & house batteries charged.

Good luck with finding an option that suits your need...

I actually put in a simple toggle switch on our propane detector. Too many false alarms and now I can shut it off if necessary for the rest of the night. If that is all that is draining your battery it would be a one time pain to put in but then easy to use.
But, doesn't your 5er have a battery off switch somewhere to keep battery from being drained?

A small portable solar panel with a charge controller is all I use. I just bungee it so the wind doesn't blow it off. If it's cloudy for a week you will have to plug in though.

I am obviously missing something.
A. Why is it unnecessary to leave it plugged in.
B. If you can plug the RV in where it currently sits why would you need a log extension cord to run a charger?

I have a nice solar set up for our house batteries and have a 15W Solar Battery Tender for our chassis battery, it works excellent. I would bet it would be great at keeping everything up on your hauler: http://amzn.com/B004Q820TQ

Not sure. Just got it this summer. It's a 13 heart land torque 301

A) all I would need is the fridge . But why power the whole rv when I could bring the food in the house.
B) it's a 30 amp hookup on the rv and I don't have a dedicated outlet. I use am adapter on a 110 outlet in garage. This is with 2 cords that are 50' The battery being in the front of rv would need an even longer run

The solar charger looks like a great solution. Thanks everybody

A solar charger would probably be best for your situation.

Isn't there some risk of sulfation using a small (100 Watt 5-7 Amp) solar panel on the battery? I ask because I just installed one and worry about using it to keep the house battery charged for extended periods.

I see your quandary of having that much cord running across the yard but you talk like the RV will be a power hog if it is plugged in. IT may have a built in charger that may slowly cook your battery or really not charge it properly and run the CO detector but other than that it wont be consuming that much power.

If you have a battery cut off switch, that should eliminate the draw from things that use battery power. Before we were full timers, we just shut off the battery cut off switch and turned off the fridge. The battery was fine until the next time we used the toy hauler. We only removed the battery when we winterized.

I can tell you for a FACT, that the battery cutoff does not necessarily cut off everything

Maybe some do, but I had two brand new upper end 5'ers that would kill the batteries in a week or so. haven't tested the Monaco yet as my storage area now has a 20 amp plug I can use !!!!

Plug in the RV as you have done.....then use one of the outlets in the RV to power the battery charger....no need to run an extension cord separately to the battery charger.....you can also permanently mount a trickle charger and wire it in so its always charging the battery when RV is plugged in.


This also might be an option for you.

Simply remove the negative battery cable when the 5er is unused. That removes all battery drain. When I used to do that the batteries would hold charge all winter.
