A PTC device suitable for attachment to a terminal of a battery. The device contains a PTC component which has a shape with an outer periphery and an inner periphery which defines a first opening in the center of the PTC component. The PTC component is made from a laminar PTC resistive element which is composed of a PTC conductive polymer composition, a first laminar electrode which is attached to a first face of the resistive element, and a second laminar electrode which is attached to a second opposite face of the resistive element. Also part of the device are a first conductive lead which has a first part which is attached to the first electrode, and a second part which extends into the first opening, and a second conductive lead. The second conductive lead has a first part which is attached to the second electrode, lies within the outer periphery of the PTC component in a plane, and defines a second opening which at least partially overlies the first opening, and a second part which is attached to the first part of the second lead, extends away from the inner periphery of the PTC component toward the opening, and can be bent out of the plane of the first part of the second lead away from the first conductive lead. When the second part of the second lead is bent out of the plane, it allows a welding instrument to be inserted into the opening created, thus allowing direct welding of the device to the terminal.
