Battery run down

You don't need to remove the battery when not in use. Just get a disconnect switch and mount it in the positive line at the battery. Turn the disconnect switch off when your storing the trailer and not plugged in and the battery will stay charged for several months.

If you can charge a few times at the storage place, with a portable charger, that's what I'd do. If not, I'd remove it, take home, charge several times over Winter. While it may work on a fully charged battery, to disconnect, let it sit all Winter, it will run down some. The more times run down to 50 percent, or less, will shorten battery life.

Thanks a lot for the quick replies. I do have an adopter so I'll plug the house electricity into the trailer. The dealer I bought the trailer from said that over the winter all I had to do is disconnect the battery and store it and it would be OK. Is that wrong?

Yes, or just leave it plugged in. The inverter will keep the battery topped off. If you can't or don't want to leave it plugged in 24x7, then yes - remove the battery. As someone else mentioned, there's all kinds of stuff that will drain the battery if you leave it connected.

I leave mine plugged in 24x7 when I'm home. Despite being nearly 4-year-old cheap Wal*Mart batteries, they still have decent life when not plugged in.

I'm new to this too and I just unhook the neg battery cable every time I put it back in the storage lot.

If you left your battery "dead" that long more than likely it is dead. Read RV battery basics online.

'Car' will MAINTAIN a trailer battery that is already charged....provided you have a 7 pin trailer plug and charge line is hot.

But vehicle charge wire is small gauge, long and is dependent on vehicle charge system

Trailer has parasitic drains on the DC system
Hardwired LP detector, radio memory etc.
Trailer battery just sitting in storage will drain down within couple weeks.
This is NOT good for battery life
Need to get that battery charged back up now that it is run down.....then if possible plug trailer into AC power and keep battery charged via trailer converter/charger system. Otherwise.remove battery and put on portable charger.

You should check the battery for level in each cell and add distilled water if needed. the battery may not be good.If you can plug into a house circuit with adapters to convert your 30 amp to regular house outlet it should charge your battery. When you are plugged in your converter provides 12volt and charges your battery. when plugged in to power your battery should be receiving about 13.6 volts which you can check with a meter.Your tow vehicle may charge it depending how your 7 pin adapter is wired.
