How to get longer life from your Canon bp-2l14 battery pack?
Turn off the LCD and use the viewfinder.Minimize photo previewing: The LCD consumes a lot of energy.Do not use continuous focus when not necessary: Every time your camera focuses it consumers energy. The motors that move the optical components in order to focus consume a lot of energy. You can not avoid focusing of course but you can avoid focusing that is not necessary. For moving objects such as in sport events continuous focus is used so your can stay focused on the object until you are ready to take the photo. In those cases as long as you press the shutter button half way down the camera will continue to focusing on the object.If you plan to shoot a photo of a runner at point A only press the shutter when he gets close to that point. Holding the shutter button down and following the runner for a longer time than needed to capture him at point A wastes a lot of the Canon bp-2l12 energy.
