I have EXACTLY a same symptoms however the battery is 500 miles new.
Cold morning - start car - front heated screen on, then... Clicking starts until heated screen turns off. Clicking stops...
Not a problem just !Removed! annoying! Car hasn't skipped a beat, just !Removed! clicking upon first start.
