For short term storage (less then 3-4 months) I would just turn the switch to 'off' or disconnect the positive battery cable (hook it back up BEFORE you plug in to tow vehicle).
For that to be good advice, you have to add "have the battery fully charged before disconnecting". And if there is some age on them already, they might have significant losses in 4 months.
It really is best to give them an overnight boost charge once a month.....or use a full time tender.
Agreed.
I didn't go any further with my comments because it sounds like the OP is storing the trailer in a lot. He states that 'he left the trailer'. Most lots don't have electricity available so I'm guessing he can't plug in a charger for the battery.
I also 'assumed' that the battery would be fully charged since it would be connected to a tow vehicle and towed to the lot. Yes, I know you don't get a high charge from the TV.
In any event, all your points are valid.
