Non-intrusive battery status indicator and inventory system

An apparatus and method of measuring and/or determining the status of battery parameters by receiving and/or decoding an RF information signal from a sensor/transceiver located in the target battery, where the RF information signal contains information regarding the status of particular parameters of the target battery. In particular embodiments, the sensor/transceiver located in the target battery is operable to measure battery parameters such as voltage and charge status, store particular battery parameters to and retrieve particular battery parameters from a memory located in the battery, and transmit RF information signals containing battery information regarding the particular battery parameters to a so called readout unit. The readout unit is operable to receive and/or decode the received RF information signal, determine the status of particular parameters based on the battery information contained in the received RF information signal, and display the status information. Advantageously, the present invention enables the determination of the status of particular battery parameters without having to make contact with the target battery itself.
