ABSTRACT:
A method and apparatus are provided to calculate capacitance remaining on a power source in a battery powered device. A database is provided to store data associated with past battery performance data and data associated with a battery operating the device. The battery data includes battery drainage factors associated with the battery make and model, and the percent of time the apparatus has historically operated in a particular status. An algorithm is provided utilizing current and past data associated with the power source and the associated device to calculate time remaining for operation of the device with the current power source.
