An air manager is provided for supplying air to a battery that may be disposed in a battery compartment of an electrical device. The battery includes at least one air-depolarized cell to supply power to the device. The air manager achieves a dual function of stimulating flow within the battery compartment as well as delivering air over the at least one cell. In particular, the air entering the air manager is split into two streams, the first stream delivering air to the cell, and the second stream stimulating flow within the battery compartment. The air manager may use a fan, peristaltic air pump, or any alternative air mover. The battery may have a &ldquo;Figure-8&rdquo; design to provide adjacent cell compartments that are received in a battery compartment configured to receive standard size alkaline cells.

A method for controlling air flow in a metal air battery includes confining at least one metal air cell within a cartridge, which has an air inlet opening and an air outlet opening, and moving air through any of a plurality of air flow paths within the cartridge. Each of the paths passes through the air inlet opening of the cartridge, through a diffusion tube, through a distributor tube, across an active surface of at least one metal air cell, and through the air outlet opening of the cartridge, wherein all of the paths are substantially equal in length.
