Vegas battery charging

I have a 2018 Vegas 25.3
It has been sitting for a couple months and all the batteries are dead.
I plugged into 30 amp service and let it sit overnight. Still batteries did not charge. Any direction and or suggestions on what I must do to charge the batteries.
I appreciate the help one an get on this site and want to express my sincere thank you in advance.
Chuck

Most computer controlled chargers will not charge completely dead batteries. Before charging, the charger will look of 1 to 2 volts to ensure the cables are connected correctly. Trying to charge a with the cables reversed can lead to an explosion. To try to charge completely dead batteries, you just need to attach a good battery in parallel to the dead ones and see if the dead ones will take a charge. Flooded batteries seldom recover from a deep discharge. My recommendation is to take the batteries and have the charged and load checked. Any battery dealer can do it for you (Interstate, Walmart. Autozone, etc).

If you had the use,store switch in store, it uses power from the coach batteries to latch in use position. Which in turn will connect the converter when on shore power. You must get some voltage in the batteries by external charger , jumper to make it work
