Provided is a use of a vegetable oil high in monounsaturates as dielectric and heat-transfer fluid in a device for the generation, storage, conversion andor distribution of electrical energy. The method comprises determining that a last re-segmented protocol data unit segment of a re-segmented PDU has not been received. The elastomeric joint allows movement between the support member and the electrode to compensate for thermal expansion as a result of temperature cycling of the electrode assembly. A pair of tabs spaced laterally relative to each other extends downward from the recessed portion and rearward of the guide surface. The at least one spring is mounted between the base and the upper cover.
