The Canon LP-E6 Rechargeable Lithium-ion Battery Pack (7.2V),
has a capacity of 1800mAh, making it possible to shoot up to 850 shots
at normal temperatures on a single battery charge. The battery is also
more compact and lightweight than previous battery models.
The
LP-E6 battery also communicates with the EOS 5D Mark II, 60D and 7D
digital cameras, so that you can always check the remaining capacity on
the camera's power source info screen. In addition, a unique feature of
the LP-E6 battery pack is that it has a microchip encoded with an
8-character serial number. So when the battery pack is installed in the
camera, you can register it using a menu command. Then track the
condition and power characteristics of up to 6 batteries in your camera
to ensure you use your batteries evenly and identify batteries that are
near the end of their useful lifespan.
