Should I leave my battery plugged into shore power in cold
Dear RVers:
My 30' Class C 2007 FR Sun Seeker is parked outdoors on my lot in Poconos PA, where lately we're averaging 5 degrees during the day. I had it professionally winterized in October, and that RV tech told me "do not leave your house battery just plugged in, it will dry up your battery." So I obeyed that, and come every week and plug it in to the house 110-volt outside plug and leave it that way 24-48 hours, and that gets the house battery charged up. I also start the truck engine, which I've read is NOT getting cross-charged just by plugging in the house battery to the outdoor shore 110-volt shore power.
I am noticing that my house battery is going down to 30% every 4 days or so (unplugged) in the cold, and being as we're in the coldest part of winter, with average this week and next in 5 degree range, I am very tempted to plug the RV into my 110 volt outside electrical outlet and leave for warmer climes for at next 2 weeks or so. I will leave the RV volt systems turned "on," as I've been instructed, otherwise the charging process is futile (I've been told). I understand that this will charge up my house battery, but not the truck battery. All fine.
What I am worried about is that I'll "fry" dry my house battery by doing this for two weeks. Any ideas, folk? Is this likely in 5 degree average temps? If it's true, that means I have to go back and forth, back to Poconos, coming from NYC, plugging and unplugging, which I am finding unpleasant and is like babysitting hens in a hen house.
Thanks for any advice. I want to plug it in and leave it for 2 weeks.
Sincerely, Gabriela
