Abstract
An apparatus is provided which comprises: a first circuitry to estimate variation of an internal impedance of a battery; a second circuitry to estimate a high power that the battery can supply for a first time-period, based on the estimated variation of the impedance of the battery; and a third circuitry to facilitate operation of one or more components of the apparatus in accordance with the estimated high power for the first time-period.
