Newmar new air chassis batteries

[Cablemandan]

Does anyone know if the Newmar new air 2020 model is set up to keep chassis batteries charged while plugged in
Thing as they did discharge and are 3-1/2 yrs old, may need replacement?
I did have a cigarette style fan plugged into a lighter style outlet for week or so. Keep air moving around while storing
May need to use traditional house plug home type instead
Thks
Man this site has changed slot since I last logged in, liked the old style better
How do I attach my personal stamp?

By personal stamp do you mean signature line ?

In the User CP , click " Edit Signature " enter the info and click save at the bottom of the page.

Most interconnect systems require that the coach batteries reach a minimum state of charge before they switch to also charge the chassis batteries , are the coach batteries in good shape?

When my coach is plugged in both sets of batteries are kept charged. I'm not sure about the voltage that Skip426 is talking about. I haven't had a problem where it stopped charging either set of batteries. Maybe I should add "yet" to that comment!

The BIRD battery interconnect system in my vintage coach , requires that the coach batteries be above 13.1 volts for 2 1/2 mins , before the system starts to charge the chassis batteries .
I can't say if the interconnect system in use on newer coaches needs the same .
