I recently bought the LP-E4N battery pack to replace the original (LP-E4) I got with the 1DS Mark III. According to Canon, this new battery pack is compatible with the 1D Mark III and IV cameras models:

I would like to hear from people that are using this battery with these cameras if anyone have experienced the same issue that I am having. I have bought 2 LPE-4N's (new, manufactured in July 2012), and with both batteries the camera will occasionally lock-up. The power will stay on, but the camera is completely freezed and the only way to shot it down is to pull out the battery.When I the insert the battery again it will work as normal for a while. I have had never experienced a similar issue with the LP-E4.
The issue happens sporadically and appears to be completely erratic, at least I have no idea what causes it and I can't reproduce it at will. I have tried different shooting modes (one-shot and AI servo) and drive modes and even lenses.
I made a complete calibration and recharge of the batteries when I bought them on my LC-E4 charger. I am starting to wonder if issue with the new battery pack could somehow be caused by the higher capacity or safety changes to comply with the Japanese standards... At this point it seems to me that it must be a compatibility issue with the new battery, as I have never experienced any issue with my original LP-E4.
Thanks in advance for your feedback to anyone using this camera/battery combination!
