If some part is connected to Earth, that''s usually called 0V. Otherwise, the battery''s negative terminal is usually 0V. But it doesn''t have to be. So if you charge up a capacitor to some voltage, and then connect the positive terminal of the capacitor to the point you call 0V, then the negative terminal must have a negative voltage.
