Just for the sake of pedantry, "nominal" only means that it's called that;
it's derived from the Latin "nomen", which means "name", i.e., "nominal"
pretty much translates to "in name only".
And of course, the appropriate rejoinder here is that the "ground" that
the battery's terminal is connected to is also "only" a "nominal" ground. :-)
