Why do you want to keep 12v connected in storage? Just curious
I have and use a battery disconnect switch on my trailer when in storage.
Due to health issues, I was unable to perform any maintenance on my trailer for seven months, last year. In that time, the batteries had run down significantly. That is why I felt compelled to take some action. The easiest thing for me to do was the small solar panel. I will see soon enough if it was a good decision or not.
I am encouraged that you get great life out of the battery by charging before storing and disconnecting cable. Thanks for your advice.
if there is significant drain with the disconnect open then you must have something connected "ahead" of the disconnect, perhaps the breakaway switch or tongue jack? Try disconnecting the ground wire AT the battery.
