Battery contact spring

The invention relates to a battery contact spring, in particular for battery-operated, hand-held units. The problem of the invention is to produce a battery contact spring that can be made of an inexpensive and available raw material in an advantageous production manner, and which is characterized by an advantageous operating performance. This problem is solved according to the invention by a battery contact spring having a spring body manufactured as a flexible wire part that has a first contact head section for contacting a first battery, a second contact head section for contacting a second battery, and a first spiral spring section that extends between a spring foot area and the first contact head section and which flexibly supports the first head section vis-à-vis the spring foot area, wherein the spring body is designed in such a way that a coil end of the spiral spring section lying far from the spring foot area crosses over into the first contact head section and attached to this first head section is a connection bridge that crosses over into the second contact head section.
