Abstract: An integrated circuit, typically a random access memory, is housed in a package (14). In the application associated with the integrated circuit it is desired to maintain the data states stored in the memory even when the normal supply voltage is disconnected from the package (14). Batteries (24, 26) are secured in recesses (20, 22) within a structure (12) which is connected to the integrated circuit package (14). A top spring clip (100) is provided to securely hold the batteries (24, 26) within the recesses (20, 22) and forms a common conductor in contact with the upper terminal of both batteries. A bottom spring clip (74, 76) is provided for each of the recesses (20, 22) to form separate conductors in contact with the lower terminal of each battery. The batteries can be readily inserted and removed over lips (64, 70) in the recess (20, 22).
