In this work a study about the energy-momentum of a new four-dimensionalspherically symmetric, static and charged, regular black hole solutiondeveloped in the context of general relativity coupled to nonlinearelectrodynamics is presented. Asymptotically, this new black hole solutionbehaves as the Reissner-Nordstr\"om solution only for the particular value{\mu}=4, where {\mu} is a positive integer parameter appearing in the massfunction of the solution. The calculations are performed by use of theEinstein, Landau-Lifshitz, Weinberg and M{\o}ller energy-momentum complexes. Inall the aforesaid prescriptions, the expressions for the energy of thegravitating system considered depend on the mass M of the black hole, itscharge q, a positive integer {\alpha} and the radial coordinate r. In all thesepseudotensorial prescriptions the momenta are found to vanish, while theLandau-Lifshitz and Weinberg prescriptions give the same result for the energydistribution. In addition, the limiting behavior of the energy for the cases rtends toward infinity, r=0 and q=0 is studied. The special case {\mu}=4 and{\alpha}=3 is also examined. We conclude that the Einstein and M{\o}llerenergy-momentum complexes can be considered as the most reliable tools for thestudy of the energy-momentum localization of a gravitating system.
