A battery system includes an electrical storage cell having a positive terminal and a negative terminal. The electrical storage cell is provided with a normally open bypass circuit path that is closed in the event of an open-circuit failure of the electrical storage cell. The bypass circuit path includes a first electrical conductor connected to the positive terminal of the electrical storage cell, a second electrical conductor connected to the negative terminal of the electrical storage cell, and a shorting gap between the first electrical conductor and the second electrical conductor. A mass of a fusible material is positioned at an initial mass location. A spring is positioned to force the mass of the fusible material from the initial mass location, along the metal flow path, and into the shorting gap, when the mass of the fusible material is at least partially molten. A heat source is activatable upon the occurrence of an open-circuit condition of the electrical storage cell. The heat source is operable to melt at least a portion of the mass of the fusible material. The spring forces the molten material into the shorting gap, where it solidifies and closes the shorting gap so that the first electrical conductor is in electrical communication with the second electrical conductor.
