Disclosed is a method for operating a rotor blade adjustment drive for a wind turbine, in which an electric working load (23) is powered by an electric primary power supply (26) and, in case of a failure of said primary power supply (26), by an electricity accumulator (20). The accumulator (20) is charged by an electric charger (22). Furthermore, the accumulator (20) is temporarily disconnected from the charger (22) at successive intervals, and an electric test load (30) is applied thereto, the resulting electric discharge of the accumulator (20) being observed. |
