DSTELP-E4N Li-ion Battery Compatible with Canon LP-E19, EOS-1D X Mark II, EOS-1D X, EOS-1D Mark IV, EOS-1Ds Mark III, EOS-1D Mark III

Unlike many others this actually works. I have purchased a number of spare batteries for my Canon 1D X and this is the first that works in the charger and the camera's on screen capacity gauge. Has a higher capacity than the Canon battery so that is another plus. I did buy a spare Canon battery but that is now starting to fail and given the price of their replacement looked at other options. This is the best I have found including some that would not even fit in the camera. Don't know about longevity yet but all looks good now. You can buy with confidence and much, much cheaper than Canon.

Yes it really does communicate with both my Canon 1DX mark I and II. THe OEM version of this battery is three/four times more expensive.Cant say how many shots I will get with it but its rated at 3350mAh so it should be goodFootnote. Canon have stopped selling the LP-E4N battery for the 1DX mark 1 but this battery will fit and communicate with the camera. (many dont)PS I was so impressed I bought 2

Can't say much more - a fraction of the cost of a Canon replacement - holds charge well, fits, works.. great

This is my second. Like to work with two batteries. They charge easily and hold as much power as the original Canon batteries. Little bit dearer than some available but you get what you pay for.

Although the battery powers up the camera and communicates with it (Canon 1DX Mk 2), it is a very loose, sloppy fit thus rendering the weather sealing of the camera useless. The weather sealing on the 1 DX Mk 2 is absolutely phenomenal, and this battery renders it useless. The battery fit is so loose that it rattles when changing orientation from landscape mode to portrait mode. It does have a silicone weather sealing strip built into it, but it is useless as it doesn't get compressed due to the sloppy fir. It will be ok in an indoor, dry dust free environment but if you use your camera in wet or dusty conditions, as I do, then avoid it. I ended up buying the genuine Canon battery for my own peace of mind and knowing how great the sealing is.

Registers in camera (1dx) as a Canon battery and charges on original charger. Shot almost 2000 images on first charge and still 10% left. So far, so good.

Excellent service and product met my expectations.

The OEM versions of this battery are quite expensive so having used DSTE branded third party batteries on my other cameras was quite happy to buy their version. I was not disappointed because it does the job very well.
