DSTE Replacement for LP-E4N Li-ion Battery Compatible Canon EOS-1D X EOS-1D X Mark II EOS-1D Mark III EOS-1D Mark IV EOS-1Ds Mark III as LP-E19

They fit, they charges up and they are in use.

It isn’t the best battery but due to a shortage or unavailable canon e4n’s it’s fair.

I waited a few months after purchasing this replacement battery for my Canon ID-X, so I can give a best accurate opinion. Brief and to the point: I am very satisfied with this replacement battery! This battery has kept full and reliable charge as needed.

So far this is been a great replacement battery. I Purchased this as a back up for photographing a camp for kids with cancer. It performs great. The only drawback that I have experienced is if it’s left in the camera for more than an hour, my EOS 1D Mark III stops recognizing the battery level. All I’ve had to do though is pop the battery out and put it back in. Once that’s done it recognizes it again.

The description of this battery says it is compatible with my camera, an EOS 1DX. My first picture shows the undersides of my original battery and this one that I received. The battery's underside has a wide flat bottom groove with two narrow tabs on each side. I have circled in red a tab on each battery. The tab on the battery I received is clearly much longer than my original battery. This tab prevents the battery from sliding fully into the camera or charger.The second picture is from the Amazon product page, the only picture that shows the battery underside. In the picture this same tab is visible and it is NOT extra-long but appears to be the same length as my original battery. The battery I received is not the battery pictured on the product page.

Works great for 1dx Mark ii!

Exactly as described.

UPDATE: I had to return one due to the fitment issue. Got shipped another one and the fit seems fine.All but a couple of details of battery seem fine. The fit isn’t perfect. The release latch is way too firm and tight. That said so far no other issues with performance of the battery.
