A primary metal-air power source containing one or more metal-air cells incorporating an air manager in a power source housing of the power source. The power source provides intermittent use at high power levels over a long lifetime while demonstrating a high utilization of the metal, such as zinc, making up the metal-air cell's metal anode. The power source provides 80% of its amp hour capacity for at least 30 days after the initial partial discharge at a power level of at least 50 milliwatts. The cumulative run time may comprise any number of intermittent connections to a load having varying duration. The ventilation system of the power source draws ambient airflow through an isolating passageway by operating an air mover which distributes the airflow to the metal-air cells. A portion of the airflow is recirculated by the air mover and returned to the metal-air cells and the remaining portion of the airflow is moved through a second isolating passageway to the exterior of the power source's power source housing. The movement of airflow into and out of the power source is minimized during in-service storage.

[ What is claimed is:] [1.]1. A power source, comprising:a power source housing defining a chamber containing a cell including an air electrode isolated from an environment surrounding said housing except for an inlet diffusion tube;a fan housing communicating with said chamber, said fan housing including a fan having a rotating fan blade, an outlet diffusion tube extending from said fan housing tangentially with respect to a periphery of said fan blade to direct a flow of air between said fan housing and said environment;an air flow path defined within said chamber passing radially from a fan housing opening, then adjacent to said air electrode, and then axially into said fan housing through a fan housing inlet;said diffusion tubes restricting air flow between said air electrode and the environment surrounding said housing when said fan is not operating and said diffusion tubes are unsealed.
