Contrary to what you say the battery clearly has already leaked, just not
as bad as with many other cases.
The greenish residue around the vias and IC31 legs is a clear sign, so are
the dark spots on the large trace near the battery.
You should remove the battery at once and give the board a thorough
cleaning. Perhaps the board still can be saved.
