Based on the question, I am assuming that the user who is running the bat file is a standard user and not an administrator and does not know the administrator password. Is that a correct assumption?
If so, is this what you are looking for?
standard-users-run-program-admin-rights
There is no magic switch to allow a standard user to gain administrator access without somehow providing administrator credentials. That would be a security hole. Of course if you save the credentials of the administrator account as that page describes, that may also be a security hole.
There may be other alternatives (task scheduler) that you could use, but you would need to explain more about what you are trying to accomplish.
