Canon LP-E19

New levels of shooting performance - mean that the EOS-1D X Mark II needs an even more powerful battery than in previous generation EOS-1D cameras. To meet these demands, the EOS-1D X Mark II is launched along with a higher-energy battery, the Canon LP-E19 battery pack. Canon's EOS-1D X Mark II ships with a battery having greater capacity than any previous battery for EOS-1D series cameras. The Battery Pack LP-E19 has about 10% greater capacity than its predecessor, but still can be used in EOS-1D and EOS-1Ds models as far back as the Mark III versions. New battery pack and charger At 2700 mAh, this battery has about 10% higher capacity than its predecessor, the LP-E4N battery pack. It's readily identified by its light grey colour and a red stripe on its upper surface. The LP-E19 battery pack continues to provide full battery information within the EOS-1D X Mark II's set-up menu, displaying the following: Type of battery in-use Remaining percentage of charge capacity, displayed in 1% increments Shutter count since this battery last charged Recharge performance - the relative ability of this battery to retain a charge Backward and forward battery compatibility The new LP-E19 battery pack is the same size and shape, along with the same electrical contacts, as previous EOS-1D-series batteries. So if you use battery packs for the EOS-1D Mark III or Mark IV, EOS-1Ds Mark III, or the EOS-1D X, you're in luck: There's extensive back-and-forth battery and even charging compatibility. Here's what's possible: New LP-E19 battery pack Can be used in EOS-1D X Mark II Can be used in previous EOS-1Ds Mark III, EOS-1D Mark III, EOS-1D Mark IV, and EOS-1D X Must be charged with new LC-E19 charger (with red stripe on charger's top surface) So the new battery pack requires the new charger to fully charge it; if you do use an older battery pack in the EOS-1D X Mark II, there's a slight drop in maximum shooting speed to about 12 frames per second (from its normal 14 fps maximum speed).
