3.10 Battery Status
Battery status is displayed as a single battery icon shown in the lower-
left hand portion of the LCD. Since the voltage curve of the battery pack
drops off rapidly towards the end of its charge, the Battery status icon is
useful only in showing when the battery pack is nearing depletion. It
does not show the pack’s remaining percentage-of-charge.
4.0 volts and above
(Shutdown imminent, less than 5 minutes of operating time remain)
