Abstract
Diagnostic use of physical and electrical battery parameters is made to enhance battery authentication and security. A power management module measures an electromagnetic radiation spectrum of a battery module based on signal strengths of the electromagnetic radiation detected at one or more antennas. The measured electromagnetic radiation spectrum of the battery is compared to a reference electromagnetic radiation spectrum, which may be specified for authentic batteries, for example. If the measured electromagnetic radiation spectrum corresponds to the reference electromagnetic radiation spectrum, the battery is authenticated for use with the mobile communication device. A relative condition of the battery, such as an age or state of health, may also be estimated based on the measured electromagnetic radiation spectrum of the battery module.
