ABSTRACT:
A battery pack includes a housing. A first battery is located in the housing, the first battery using a first cell technology. A second battery is located in the housing, the second battery using a second cell technology that is different from the first cell technology. The battery pack can be connected to a portable computer chassis to provide an extended life power source. Each battery is coupled to an independent battery management unit (BMU). Each BMU shares a common connector.
