  The second post-Newtonian solution for the quasi-Keplerian motion of a test
particle in the gravitational field of regular Bardeen black hole is derived.
The solution is formulated in terms of the test particle's orbital energy and
angular momentum, as well as the mass and magnetic charge of the Bardeen black
hole. The leading effects of the magnetic charge on the test particle's orbit
and motion including perihelion precession are displayed explicitly. In
particular, it is shown that to the second post-Newtonian order the magnetic
charge does not affect the test particle's orbital period.
