This is exactly what I do for my tractor every Fall. I used to have to replace the battery about every other year, but since I started putting it on a maintainer five years ago, it has not had to be replaced even once since that time.Another option is to hook it up to a trickle charger or battery tender.
ConfirmedIt's good to read that when the battery is disconnected the settings are not erased, because setting all the radio and destination favorites in the system took a long time.
I forgot to mention:After I had reconnected the battery after three months, no settings were lost.![]()
