battery life is: Continuous recording 120 minutes (720 shots), continuous playback
220 minutes. Battery life is highly dependant on operating temperature and the amount
of time the color LCD or the built-in flash is used. The supplied BC-30 charger takes
approximately two hours to fully charge a depleted pack.
