A battery system for use in a battery-operated device, such as a rescue light or radio used in a hostile environment, employs at least one battery element contained within a tubular support member. In embodiments which employ multiple battery elements, the battery elements are in electrical communication with one another, illustratively by welding or soldering their teminals to one another. At one end of the tubular element, a terminal of the battery system is covered entirely by a seal formed of a resilient material. The seal additionally closes the entire end of the tubular member. At the second end of the tubular member, a second seal is provided for closing the second end of the tubular member, but not covering the second battery supply terminal. The battery system operates in conjunction with a housing for the battery-operated device which may have arranged therein a pointed contact which penetrates the first seal so as to achieve electrical communication with the first contact of the battery supply. The battery supply is urged toward the pointed contact by a spring which is contained within a closure member which seals an aperture of the housing of the battery-operated device. The spring is configured so that it will not penetrate the first seal in the event that the battery system is incorrectly installed in the rescue light. In other embodiments, the contact within the housing is blunt, and penetration of the seal is achieved by a pointed portion on the spring.
