Can you leave an AS plugged in in storage?

Hi All,

Is it OK to leave an Airstream plugged in to shore power all (or most) of the time?

For our previous non-AS trailer, the answer was no per the manufacturer because the charger would eventually "cook" the battery; it wasn't smart enough to deal with constantly being plugged into shore power.

Any ideas if an AS could handle that? If not, any ideas what it could handle before it should be unplugged (days, weeks, months)?

Thanks in advance,

I would think with a 2012 you would have a converter with a 3 stage charger and if so yes you can leave it plugged in.

What converter (charger) do you have ?

In another current thread, it was pointed out that even today, new trailers do not come with a multi-stage converter.

If this is true, I would not recommend leaving the power always on. It is possible that this could destroy the battery.

I replaced the old uni volt system in our '66 Trade Wind with an intellicharger. 6 years on always 24/7/365 and still have the same battery.

I leave the trailer plugged in when stored here at home. It has it's own shelter and a modern converter. But I also remove the battery and store it in my shop where I have a RV/marine intelligent charger on a timer. Going on the 4th year with the same Wal Mart battery.

If you have a single stage charger (I have no idea what AS provides today) you could put the thing on a timer, set for say an hour a day and you would be ok. If it is a 3 stage "smart" charger you could leave it on all the time.

I don't really know the proper answer. We have a 2005 Safari 25FB that we have had since new. We always leave it plugged into shore power with either the air conditioner or heat pump on. We also leave the refrigerator on and cold with food in it. Our Airstream has been plugged in for as long as two months straight between trips.

Our OEM batteries lasted for 5 years before we needed to replace them.

We leave our rig plugged in all the time, with the frig running ... and the AC set to come on if it reaches a certain temp inside...

No problems so far...

I fried 2 AGM batteries keeping it plugged in with the original charger. Trailer would sit for 3 - 6 months not being used. Changed out to an updated 3-stage charger with a battery conditioner added. That was over 2 yrs ago and no problems now keeping it plugged in

I don't see why leaving it plugged in is any different than living in the AS all winter in a warm climate like Florida. I am sure that mant users here are snowbirds, do they remove the batteries?

Yup, as TG said.. Don't forget to disconnect the batteries as they will burn out pretty quick.

???storage??? If this is at your home you can keep an eye on it, its one thing. If it is not where you can check it every day, 3 stage charger or not, I would question their electrical supply (outages, spikes, etc). If the only reason you want to keep it plugged in is to keep the batteries charged, I would pull it/them and keep them home to monitor.

Our Airstream is always connected to shore power at all times. So far no problems with the batteries
