To store charging or disconnected?

I know this has been discussed in forum somewhere but just checking to get options on couple week storage settings. On my previous coach if I left plugged up and charging, it would boil batteries dry over time and i had to cycle every 5 to 8 days with charging. This coach says it is float charging but i do not want to over charge. What do y'all have experience with?THANKS

I stored my Aspire charging and saw no ill effects. I do the same with current rig, but different batteries.

I don't have an Entegra, but I have a similar system with a Magnum inverter and 8 batteries. I always leave it plugged-in to a 50A service. If you have them filled properly, and your Magnum is set up properly, you should not have a problem. You just need to check the water level once a month. One way to assure the batteries are filled properly is to install a watering system like the Pro-fill. lt prevents over filling because each cell has a float mechanism. It also reduces the labor to about 45 seconds to fill all the batteries at the same time.

I store mine unplugged and run the generator for about 2 hours once a week.

Mine is stored 3-5 months plugged into 50A source from house and have had no problems. The chargers show float charging after they are up to full charge.

I keep mine plugged in to a 20 amp circuit from the house all the time. It generally sits from November to March without ever cranking it. Never had a problem.

Charging in storage between uses - either plugged in or via solar.

The OP probably realizes this, but I will remind...he has wet batteries and all who are posting with Anthems or Cornerstones have AGM batteries. AGM batteries never require maintenance (adding distilled water) and are therefore less likely to be damaged by staying plugged in for long periods of time. I personally would leave it plugged in. As mentioned, if the charging profile in the Magnum is set properly and water is added/checked every 60 days it should have no problem and will be less likely to be damaged by going dead with parasitic loads, etc.

I leave ours plugged in too...but it has AGM's.

I leave ours plugged in all the time to at least 20 amp if not 50. I just check the batteries about every 45 days just to make sure. I think I have only added water twice and that was due to the fact that when I was having it serviced they left it unplugged and it was dead when I went to pick it up.

The Magnum has a nice battery saver mode that will automatically shut off all charging including the float charge after a period of time, monitor the voltage and turn it back on as needed. We are full time and see this mode invoked regularly. This should greatly reduce the possibility of overcharging or boiling dry. I think for a just a few weeks your batteries would be happier plugged in.

My Travel Supreme was the same way, it would boil the batteries dry in no time. I bought custom caps, reset the inverter/charger nothing worked.

The Entegra with the newer up to date chargers I think that problems has been eliminated. I have not heard of an Aspire owner that have asked about batteries begin boiled dry. It was a common post on the TS forum years ago.
