My two coach batteries wear down when in storage. Everything is off as far as I can tell. TV is unplugged also. Wears down in a week. Is there a battery disconnect I can use to prevent this?
I have a motorhome not a Salera but I'm sure their is a battery disconnect some where.
If you do not disconnect batteries while in storage you still have power to your propane detector which feeds 12 volts to propane safety tank valve. The only other things might be your refrigerator controls, water pump and lights.
This is what my battery disconnect look like at my entry door.
I'm sure someone will pop in here and tell you where it is located.
Round switch in stairwell. On left side as you enter. Unless this is turned off, propane/CO detector and the associated propane valve are "on" - these will slowly run down your batteries. Other parasitics include the radio and TV memories, and, if you have the Schwintec (sp?) slideouts, the "brain" for that device. (On my Solera "S", no parasitic slideout electrical drain.) I don't know if the master switch turns off the Schwintec brain - I don't think so. Also, if you have the optional leveling system it may also has a control module which draws some power all the time (I don't have either the Shwintec slides or the self-leveling option on my Solera).

[QUOTE=herk7769;378003Adding a battery cut out switch (or using it if you have one) will extend it to about a month; but a "keeper" or "tender" is the only way to keep one charge and healthy all winter. (solar or plug in)[/QUOTE]
With the understanding that the house batteries and the chassis battery somehow are connected so that they both charge when plugged into 120V, I'm wondering is there is a connection somewhere that a battery tender could be placed that would keep a trickle charge on all the batteries at the same time? Anyone have any ideas?

I do not have a motorhome, Solera or otherwise, however I do have a schematic of a "generic" battery control center (I believe it is Georgetown's).
It should help you find the "points of commonality" to attach your tender.
It is my understanding (by looking at the circuits and reading the manual) that the point the generator, converter, and alternator attach to the battery control center is the common point for the positive lead of the charger and any good ground would be appropriate for the negative.
As long as that post is above 13 volts; charging of both batteries would occur.
Anyone else have more specific information?

Here is my fix. Currently going on one year of ownership and this has worked just fine for my Solera.
First, there are numerous sources on battery management for RV's which will give you a good understanding on how RV systems works in general.
The unit has a battery management system that allows this method to work. The coach batteries must be about 90% charged before you attach a "trickle" charger to one of the coach batteries. You can accomplish that by plugging in the unit to shore power to allow the internal charging sytem to get you to that point. Next, run an extention cord through the hood exhaust vent (remove alum filter) to supply power for the charger. A standard extension cord works fine. The battery management system (as previously discussed here) will keep all three batteries charged as needed. You only need one charger, connected to the + and - terminals on one of the house batteries, to keep the batteries up to snuff. I did this for my dormant period of 4 months with no loss of charge.
Be sure to check acid levels in the batteries so there is no loss of fluid during the longer charging periods. Only add distilled water if needed.
That worked for me just fine. Note: repeated discharge below 1/2 will diminish the battery life.
Your 10 days is about normal. My Solera has a 230mA drain with the batteryswitch on. For a 70 Ah battery, this would drain the enire battery in about 10 days. With the battery switch off, the drain is 130mA, which would give you around 20 days.
The battery disconnect switch is probably the most useless feature in the entire coach. It does not disconnect the battery. It only disconnects a few items. The best solution is to install a real battery disconnect switch yourself ($3 at Harbour freight).
Also, if your unit has been sitting at a dealer for an extended time (like mine did), the battery would have gotten completely drained, resulting in irreversible damage to it and reduced battery capacity (like mine did also).
Not sure which model Solera dswiss has. On our 2012 "S" the battery disconnect seems to work well. With the switch "on" the battery indicator drops to two lights after three days or so. With it "off" stays at three lights seemingly indefinitely (over a month). Believe I saw a post in the past implying that the new Schwintec (sp) slide "brain" might be a issue.
