The Canon LP-E19 is a genuine high-capacity lithium-ion battery pack for Canon's professional EOS-1D X series bodies, including the EOS-1D X Mark II. Professional sports, wildlife and event photographers use it as a spare or replacement so they can keep shooting through long assignments without running flat. Canon rates it at approximately 10% more capacity than the older LP-E4N, and the pack weighs about 185 g. Its operating specifications are matched to the cameras it is designed for, and as an original Canon battery it communicates correctly with the camera's battery information display. Carrying a charged spare in your bag is the simplest way to extend a long shoot or a trip. The box contains one battery pack; a compatible Canon charger is required for charging and is not included.
