Can someone explain how the battery back up works? Is there a battery installed in the actual opener in the garage? And then would it just open from the fixed opener one normally has attached to the wall of the garage? What about closing it (once outside)? Perhaps silly questions but I am small and really don’t like when the power’s out and I have to open the door manually. Intrigued by the battery back up but can’t visualize how it works.
