Abstract

An activatable battery for an electronic artillery fuse and mortar fuse includes an ampoule filled with an electrolyte, and an activation device for rupturing the ampoule. In order to evaluate the duration of a mechanical impulse acting on the battery, the activation device can be freed by a timing member having an inertia body which is axially and rotatably displaceable and against which a compression spring is operative. A compact structure and reliable installation of the ampoule in the battery is achieved in that the battery has an upper battery portion and a lower battery portion, the activation device is provided in the upper battery portion and the ampoule is disposed immovably in the lower battery portion.
