Canon EOS 5D Mark II & its battery LP-E6

Compared with its predecessor EOS 5D, the Canon EOS 5D Mark II has many new features. The new EOS 5D Mark II boasts a new 21MP CMOS sensor, an expanded ISO range of 50-25,600 and a wealth of improvements and new features including full 1080p HD movie recording, live view, 3.0" 920k dot LCD, DIGIC IV processor and sensor dust reduction.

With capacity up to 1800mAh, the new battery LP-E6 is much more powerful than the previous 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 based on CIPA-compliant tests performed at Canon Inc.

Moreover the battery grip BG-E6 offers unlimited battery expansion and comfortable photographing.
