Canon LP-E6 (LPE6 LP E6) Battery for Canon 5D MkII, Canon 7D and Canon 60D Cameras
Manufacturer Part No: 3347B001AA
It appears to be nearly the same size as Canon's long-running BP-511 series battery, but do not let appearances fool you. The new lithium-ion LP-E6 battery pack is approximately 30% more powerful than the previous BP-511A – with 1800 milliamp-hours capacity, vs. 1390 mAh for the previous-generation BP-511A. Even though the new EOS 5D Mark II is a substantially higher-resolution camera than the previous EOS 5D, and in spite of the added performance of its DIGIC 4 processor, the LP-E6 powers the camera for 850 shots at normal temperatures (vs. 800 for the EOS 5D), based on CIPA-compliant tests performed at Canon Inc.
