Abstract
A method for accurately estimating a run time of a battery utilized by an electronic device. The method comprises determining a starting battery capacity utilizing an open-circuit voltage of the battery, determining a battery capacity decline rate utilizing a load-condition voltage of the battery, and determining a low-voltage-alarm battery capacity during an active operation of the electronic device. The method further comprises utilizing the starting battery capacity, the battery capacity decline rate, and the low-voltage-alarm battery capacity to estimate the run time of the battery which may be determined by dividing the difference of the starting battery capacity and the low-voltage-alarm battery capacity by the battery capacity decline rate. One embodiment utilizes an open-circuit voltage lookup table, a load-condition voltage lookup table, and a low-voltage-alarm lookup table that are configured for use with a certain type of battery.
