How can I check to see if my electrical system in my 5th wheel is charging the batteries?

My unit is a 2016 and after being in storage all winter and plugged into shore power, when it is not plugged in and I go to use the electrical leveling jacks, I get a low voltage error.

If the batteries are bad, I will replace them, I just don't want to do that if they are good. I keep the water level topped off. But I suspect the batteries are just worn out.

Tools needed Digital multi meter.

Optional pencil or pen and paper

Procedure

Hook up but leave tow vehicle OFF
Hook meter to batteries in trailer NOTE voltage (12.6 eggcelent)

Start Tow vehicle
Wait 2 minutes
Re-check meter anything higher than it was means charging.
