(WO9750137-A1)      A battery is provided with a controllably operated device (7) for rapidly draining electrolyte (4) from the electrolyte cavity (3) so that the electrodes (2a, b) are out of contact with electrolyte (4) and are galvanically separated from one another. Also claimed is a second battery provided with: (a) one or more deactivator spaces which are separate from the electrolyte space and which hold a deactivator material for deactivating all the current-generating processes in the electrolyte cavity; (b) piping for connecting the electrolyte space (3) with the deactivator cavity; and (c) a transport system for controlled transfer of deactivator material from the deactivator space into the electrolyte space.    ADVANTAGE -   The battery can be converted from its operational state to a safe rest state, during maintenance or danger (e.g. after a vehicle accident), in a simple and reliable manner while avoiding battery short-circuit.
