ABSTRACT OF THE DISCLOSURE A button cell package in which button cells are releasably retained in position by an adhesive surface layer on a laminated structure having a resilient layer between the adhesive layer and a nonresilient base. An additional layer having preferential barrier properties is used with cells of the metal-air type and is located between the adhesive surface layer and the resilient member. The adhesive layer seals the metal-air cell to increase cell shelf life and prevents inadvertent dislodgment and loss of cell capacity, yet permits small amounts of evolved hydrogen to diffuse from the cell. The resilient layer serves as a cushion and provides a means for obtaining maximum surface contact between the adhesive surface layer and the button cell surface to maintain the cell in impact- resistant, releasable adhesive contact with the adhesive layer. The method of assembling the package is also described.
