Turning on the Power
When the power switch is set to <1>, the battery level will be
indicated in one of six levels: A blinking battery icon (b) indicates
that the battery will be exhausted soon.
Battery Life
The figures above are based on a fully-charged Battery Pack LP-E6, no Live
View shooting, and CIPA (Camera & Imaging Products Association) testing
standards.
Battery Grip BG-E7 approximately doubles the number of possible shots with
two LP-E6 batteries installed. With size-AA/LR6 alkaline batteries, the number
of possible shots at 23°C / 73°F is approx. 400 shots without flash use and
approx. 300 shots with 50% flash use.

The number of possible shots will decrease with any of the following
operations:
• Pressing the shutter button halfway for a prolonged period.
• Often activating only the AF without taking a picture.
• Using the LCD monitor often.
• Using the lens Image Stabilizer.
The lens operation is powered by the camera’s battery. Depending on
the lens used, the number of possible shots may be lower.
For battery life with Live View shooting, see page 137.
See the [7 Battery info.] menu to further check the battery’s condition

If size-AA/LR6 batteries are used in Battery Grip BG-E7, a four-level
