Abstract

A method of conducting an operation including a battery. The battery includes a cell having a voltage. Power is transferable between the cell and the electrical device. A controller is operable to control a function of the battery pack. The controller is also operable with a voltage at least one of equal to and greater than an operating voltage threshold. The cell is operable to selectively supply voltage to the controller. The method includes the act of enabling the controller to operate when the voltage supplied by the cell is below the operating voltage threshold.
