According to [[info:emacs#Initial Options]], --batch implies -q.
About -q and -Q, we have:

    ‘-q’
    ‘--no-init-file’
         Do not load any initialization file (*note Init File::).  When
         Emacs is invoked with this option, the Customize facility does not
         allow options to be saved (*note Easy Customization::).  This
         option does not disable loading ‘site-start.el’.
[...]
    ‘-Q’
    ‘--quick’
         Start emacs with minimum customizations.  This is similar to using
         ‘-q’, ‘--no-site-file’, ‘--no-site-lisp’, and ‘--no-splash’
         together.  This also stops Emacs from processing X resources by
         setting ‘inhibit-x-resources’ to ‘t’ (*note Resources::).

So --batch implies -q, which is enough to bypass init.el.  -Q is
stronger than -q: it adds ‘--no-site-file’, ‘--no-site-lisp’, and
‘--no-splash’ and inibits X resources.  But AFAIK, only my init.el
loads Org, and not site-start.el, which is empty here, or any Lisp
file in a site-lisp directory.  I searched every file in
/usr/share/emacs/site-lisp for "org" and I didn't find any line that
loads Org.

I am an Emacs beginner though, so I may be wrong.
