Double checked the battery again just to make sure. It is in correctly (I can read the + when I look at the board) and I am still getting 3v on one pin of a small 8-pin chip on the board indicating that the solder connections are good.
Also, the station 5 “ON” icon (expanding bubble) starts off ok, but after a few minutes gets VERY slow indicating something besides (or in addition to) thew RTC problem. You can see two videos of the problem at:
