With one charge, you can take 500 photos, and in Economy mode, even up to 600 photos. If the optional battery grip is equipped with two additional batteries, the camera has enough power for approximately 1,450 photos, and in Economy mode, even for up to 1,700 photos. When the battery is running low, the camera automatically switches to the next battery without turning off or interrupting the ongoing recording, such as video or continuous shooting.
