ABSTRACT:
A method of operating a downhole component (for example a battery pack) comprising at least one electrolyte based element. The method comprising the steps of locating the component in a downhole environment and whilst the component is in the downhole environment subjecting the element to a pressure in excess of atmospheric pressure to suppress at least one of boiling and evaporation of electrolyte in the element. The component may then be operated at a temperature in excess of that which would be tolerated by the electrolyte based element if not subjected to a pressure in excess of atmospheric pressure.
