Checking The Battery Level - Canon EOS Rebel T1i Instruction Manual

Turning on the Power

Checking the Battery Level

When the power switch is set to <1>, the battery level will be
indicated in one of four levels:
Battery Life
Temperature
At 23°C / 73°F
At 0°C / 32°F
The figures above are based on a fully-charged Battery Pack LP-E5, shooting
through the viewfinder, and CIPA (Camera & Imaging Products Association)
testing standards.
The actual number of shots may be fewer than indicated above
depending on the shooting conditions.
Pressing the shutter button halfway for long periods or operating only the
autofocus can also reduce the number of possible shots.
The number of possible shots will decrease with more frequent use of
the LCD monitor.
The lens operation is powered by the camera's battery. Depending on
the lens used, the number of possible shots may be lower.
Using the Image Stabilizer of the lens will decrease the number of
possible shots (shorter battery life).
For battery life with Live View shooting, see page 107.
