Shore power question

[Skipg]

What’s your thoughts about leaving a RV plugged in to shore power when not in use. I read it not good for the house batteries.thanks for your input.

I have left all of my campers plugged in 24/7 with onboard smart chargers. I have to add water two times each year in the summer months.

My Class B is 1999 and as far as I know has the original charger, so I don't think it is particularly smart. I'm leaving it plugged in under the carport to run some anti-mouse deterrents so I disconnect the charger and monitor the battery voltage and when it drops down a little I plug the charger back in over night. Luckily they just have the charger plugged into an outlet under the jackknife couch.

With the RV plugged into my house where I can keep an eye on it anytime I like, no real problem.

With it at a storage place which is not local to me, then I have a big problem with leaving it plugged in. I don't trust the converter/charger & I don't trust people in the storage facility leaving it alone.

New camper with one-year plug in- batteries OK.

This is consistent with old chargers often being bad for extended use and new ones generally being ok.

Double check the model if you have concerns.

I'd like to say that theory should be true, however it's astounding almost, the number and variety of cheapo converters in current production today. From battery cookers to ones that won't even charge completely. Your last words are the best advice. Find out whatcha got and act accordingly.

No. Batteries do age out. Two sets of batteries. But, they were not prematurely killed by the charger staying on 24/7/365. I got 8 or 9 years out of the first set. Still on the second set.

If you have a true multistage charger, then it will take care of your batteries. That leaves out Parallax, Magnetek, and WFCO. Since getting my Progressive Dynamics, I have left the RV plugged in and charging 24/7/365. That is about 13 years now.

IMHO, if you are storing for more than a month, disconnect the battery.

For best life, lithium batteries should not be subject to below freezing temperatures.

I leave my TH plugged in all the time. It has a 100 amp WFCO converter with no battery ill effects. YMMV.

The only time it is unplugged is when it's going down the road!

Same here !!!!

I have the infamous WFCO converter that is stuck on 13.6V. Too high for long term maintenance charge. It's a battery boiler.

I have a timer that tops off the battery for 1 hour every 3 days.

Will not hurt the battery in winter.

Otherwise post the battery voltage for best answers.
