Abstract
A battery powered device providing in combination (1) a cell pack that includes one or more isolation passageways (diffusion tubes) positioned to protect metal-air cells of the battery pack from the ambient air when no air mover is active to force air to the cells and the passageway or passageways remain unsealed, and (2) an electrical device configured to removably receive the cell pack in a manner which allows an air mover associated with the electrical device to communicate with at least one of the isolation passageways of the cell pack to provide air to air electrodes of the cells.
