Question Coach Batteries: To disconnect or not?

We're in Florida for 2 more months, hooked up to 50 amp power, and it just dawned on me that I have no idea why I haven't hit my " Battery Disconnect " switch. Now, I'm wondering whether I should, or whether I shouldn't. What is your opinion?

The only time I disconnect the coach batteries (salesman switch) is when parked with no shore power. If your converter / charger is working correctly and the batteries have proper water levels, let the system do its job. I don't know if the BIRD system (if equipped) will close the isolation relay and keep the chassis battery charged. I would be more concerned with that one.
Just my 2 cents.

Tom

Just check your water levels every two weeks or so, top off with distilled water and enjoy the warm weather!

just a technical note for those who refer to water levels in batteries and are really interested in knowing what is in a lead acid battery. Best not to measure any water. The term to use is "electrolyte",

Yes water is added but through the charging process, hydrogen molecules are released in the form of very flamable hydrogen gas.

As the discharge of Hydrogen atoms are released from H2O (water) and the solution is transformed into H2SO4. (Sulfuric Acid.)

In water there are two atoms of H and one of O.

In Sulfueic acid, there are 2 H atoms, 1 Sulfer and 4 O.

if anyone really cares

Clarifcation Atom = Molecule in an element. I used both terms that may have confused some if one really cares.

It is a lot easier to spell "water" than electrlight...electrolite... or electrolyte

When plugged into shore power the converter keeps my house battery bank charged. I have a 2 amp charger on the chassis battery. Water levells are checked monthly. When not plugged into shore power I use both battery disconnect switches.

Hi michguy,
My coach is connected to shore power, whenever/wherever it is parked. I let the systems do their job. I have used the battery disconnect switches only when replacing the batteries (so far, just one time).

With spelling errors corrected, the OP asked for the Time, don't care how the watch works.
