I use a smalll solar panel that Keeps mine trickled charged. I have a 2023 with all the options. I have lots of extras added to Mine so the battery saver mode comes on mine about every other day if I don’t drive it.
the solar battery maintainer does a great job except when their is several days of no sun. However I remote start my bronco and let it run for 15 min and that solves the issue.
