p.2 #1 · Canon R5 Mk II - battery issue in cold weather
A question I have is whether the battery or camera internal temperature makes a difference.
For example, if you fire off a few hundred frames in a short period, that usually raises the temperature of the battery, memory card and some internal components. Would that prevent the camera from shutting down for a while until it all cools down?

At -40c/40f you would have to do a lot of burst warming.
Maybe you could turn on pre-capture on and keep the button pressed 1/2 way - it will keep it warm but that solution will use battery and does not work for aurora at -40c when you are standing around waiting for the big moment.
That's back to my (less than ideal) solution I used with my old a7r2. I elastic banded a chemical warmer to the lens close to the body to keep the internal temperature higher, when it got below -20c. It's not practical to shoot bursts or video to keep the camera warm when out taking pictures of polar bears.

According to Canon the R5 II is only rated for operation from 0-40°C.
The last time I captured images from polar bears it was well above -40°C, but I probably had 1Dx something and 5DsR and/or 5DIV. I really have not had problems with Canon DSLRs in the moderate cold. I'm going outside for anything at -40°.

I have NOT read all the replies but if I missed this already being mentioned, please excuse and disregard:
I ALWAYS carry and extra battery with me...that being said..in the very cold months(not the past 5 years)I use warmer packs as this :https://thevestguy.com/products/camera-battery-cold-weather-pouch
Never a problem.
Good luck all!

I was wondering this too. OP was initially shooting video which even in cold conditions will considerably warm up the camera internals.
Extending the sleep setting when shooting stills intermittently and if the camera does not show the error, might then suggest it's not dependent on or related to internal temperature.

This comes up every so often and it's pretty much understood to be a 'cover your butt' statement by Canon and every other company. We all know the equipment works at -1˚C and colder...

Do remember when analysing possible causes (low temperatures) that wind chill does not apply to inanimate objects - it is due to evaporation from the skin surface.
Correct that the definition of wind chill is based on skin evaporation. However, a warm inadament object will cool much faster in the wind than still air. Jp

Thanks for the info on your battery issue...hoping to see someone from Canon weigh in if enough R5II users have this problem.
You will never get a direct response from Canon here about this, at least not here. They will read it though...

Op, for clarity was that 0 degrees F or 0 degrees C?
Thanks!
Low for October/2024 in Churchill was 18f [or -9c]. So it must be C. In early October the lows were just under 0c.
The r5ii should not have had challenges at this temperature. It's barely below the cover canon's butt covering rated 0c minimum.
This will be a big issue for cold weather shooters (Minnesota, North Dakota, Montana, Wyoming, Alaska, Alberta-Ontario, Northern Territories). It may even be an issue for balmy winter places like New York, Washington, and British Columbia.

I am in Churchill now and having the same issues. I had issues in Alaska in September also in the mornings( when it was cold) and I thought it was a dirty connection but since then I have cleaned the contact points on both my MKII and continue to have issues.I am running the latest software.

raj195: Did you have the same solutions. Eg 1) when you flipped the battery in and out it would work. 2) If you stopped it from sleep it would work? 3) If you put a new battery in it would come back until sleep?
I am just trying to decide whether to sell my r5v1 (or v2) or not based on the upcoming winter. The R5ii is a brick now until the spring (May for me) - unless the upcoming firmware update makes it reliable in the cold.
p.2 #13 · Canon R5 Mk II - battery issue in cold weather
Yes that's exactly what I was dealing with. I had to flip the battery in and out a few times for it to work. And yes I had to constantly keep it from sleeping or I would get the message again. I kept on pressing the back button autofocus to keep it from going in to sleep mode. I missed a lot of shots because of this. I had same issues with both the bodies! Based on my experience with the two bodies, I do not feel the MK II is reliable in cold weather.

I'm going to Haines for eagles. Looks like lows in the 20'sF. Sounds like I should take the mark I and think of the mark II as backup. I think you can set the camera in the menu so it won't go to sleep

What is the cutoff point below which the camera is shitting off?
I will be southerly in the high 30s°F to highy 50s°F (~4-15°C) ranges with two R5 IIs en Diciembre.
I only have 5 batteries for the R5 II. Am I screwed with the power failures?
I will also have the a7R5 with the 200-600 and 3 batteries, but that is more for specifically induced subjects.

Has anyone experienced this problem while using the older LP-E6NH batteries? I don't imagine many people are using these batteries with the R5 II, but I wonder if the issue may be with the new LP-E6P batteries, and not the camera?
p.2 #20 · Canon R5 Mk II - battery issue in cold weather
I tested the batteries, both the old and the new batteries and the camera has a problem with both the old and new batteries. If you go back to my initial couple of posts on this topic, I explain how we determined the problem and which cameras and batteries were tested when we experienced this issue.
I do not believe that batteries are the problem. I do believe that the problem is a firmware issue in the camera and, being firmware, it should be fixable by any relatively competent Canon Software Engineer.
