i If any file is present, you can also check the remaining battery pack charge
on the file information display (page 114).
i Battery life may differ even among battery packs of the same type.
i Depending on the usage of the camera (such as the number of times the
flash is used, the use of the LCD monitor, etc.) or the ambient temperature
(temperatures below 10 °C [50 °F]), the number of images that can be
saved on a fully charged battery pack will vary greatly.
i It is recommended that you prepare an extra battery pack(s) when taking
pictures at a wedding or while traveling, for example, so you don't miss
capturing images of important moments due to the battery pack power
running out. The same is recommended for taking photos in cold
environments. (In a ski area, for example, the battery pack can be kept
warm in your pocket until ready to use.)
