Some well-known metrics used as models of static non-rotating black holes are considered. These are the Reissner-Nordström-de Sitter, Bardeen-Kiselev and McVittie models. A significant difference between them in how adequately they can describe or be the basis for describing observed astronomical objects is demonstrated. A simple method for constructing new models of static non-rotating black holes is presented. It has been shown that a region of gravitational repulsion may exist around the horizon of a Bardeen-Kiselev black hole.
