and what defines the battery terminal as 0v ground?

really - the battery terminal can be a particularly noise prone 
ground point depending on the charging system design.. (from too much 
car sterio install experience..)

looking for a 'true' ground is usually not the solution, finding a 
non-noisy one is quite a different job - I have usually found a good 
solid frame ground to be good - you pick up so much noise on you 
earth line to the battery that it gets real bad real fast. You just 
need to find a frame ground with good conduction paths to the other 
ground references you are linked to.
