A solderless battery pack. The pack has a generally thin wall cell body portion with two tubular segments each adapted to hold a plurality of batteries. An upper end cap and a lower end cap are provided for fitting tightly over the upper and lower ends of the cell body portion, respectively. The end caps are compressingly engaged to make electrical connection with the terminals of the uppermost and the lowermost batteries by use of opposing all-thread fasteners. The all thread fasteners each extend through the upper and lower end caps and and along side of the cell body portion in a spaced apart relationship. The all thread fasteners are removably affixed by nuts below and above the end caps. In this manner, batteries are provided a complete electrical circuit without current draining soldered or welded contacts.
