Battery Disconnect?

[ronmc]

On reading info. on battery disconnect, it says to disconnect battery if it will be on converter power for extended time.Anyone do this? Mine stays on shore power/ converter power for months. Am I ruining my batteries?

I think I would disconnect from shore power and let it set a few minutes and then measure DC VOLTAGE at the battery terminals... Should read 12.6-7VDC if fully charged... If it starts dropping down below 12.0VDC rather quick then your battery is toast I suspect...

Here is a good chart showing voltage level verses charge state...


Never heard of putting mineral oil in a battery... Must be an old timers trick... MEX probably will have a good response to that haha...

Owie !
I would not be running 13.6v when the real hot weather arrives.

[ronmc]

The converter supplies 13.6 volts continuously
I used to add water each month,I added mineral oil. Now much less.

Please post the voltage on the battery terminals.
How often do you add water?

Depends on the type of converter you have...
If it has a "maintain" or "float" stage then it does not need to be disconnected.

This "float" stage will maintain you batteries at full charge without "boiling" them or damaging them.

If your 2002 trailer does not have the smart mode converter/charger chances are you may be boiling out your battery fluids over time. They don't do well with a constant 13.6VDC voltage on them for long periods of time.

If you leave it connected just be sure to keep a close check on the battery fluids...
