A method of charging a bellows accumulator for a vehicle suspension system comprises providing an outer shell with an accumulator port and a gas charging port, and inserting a bellows assembly within the outer shell. The bellows assembly includes an annular bellows wall at least partially defining a gas chamber of variable volume. The bellows assembly is axially extendable between a retracted position and a fully extended position. The gas chamber is arranged in fluid communication with the gas charging port. An accumulation chamber is provided between the outer shell and the bellows assembly and is in fluid communication with the accumulator port. The method further includes evacuating the accumulation chamber when the bellows assembly is not at the fully extended position to obtain a pressure within the accumulation chamber less than atmospheric pressure and supplying pressurized gas to the gas charging port.
