R5MkII battery discharging at 2% to 3% overnight normal?

rgp001 said:

R5MkII with all Communications set off and Airplane mode set on. IS set to shot only. Camera in still mode and turned off. Fully charged battery will lose 2%-3% overnight! If left till next day will well accumulate approximately another 2%. I don't have that sort of discharge rate on any of my other cameras, R7, 7D, 40D, 10D. Is this rate normal? Support believe it is, but told me I could send it in for service, they would check it out, but if nothing was found wrong, I would be responsible for a cleaning and checkout.

Manual recommends removing battery when not in use. Support recommended leaving the battery in to protect against settings being lost since the removing the battery will make retention of settings dependent on a capacitor with unspecified discharge rate.

The R5 - I've had batteries out for 3 months and no loss of data.

Saving the settings to card protects the settings and I'm willing to go that route, not a issue for me.

Donremember to save all settings. There are three or perhaps four files to save.

Your discharge measurements. Are you relying on the camera giving you this data?

How does it compare to a battery not in camera?

Assume BT is off?

Battery grip?

My assumption was that the main camera settings saved everything. I did notice that there were individuals settings. Does not the main camera settings save everything??? Thank you for that hint!

I didn't check that. I will do so. And report back. Might be a day or two though.

Yes BT is off (All communications is off)

Battery grip?

Same with battery grip, except one battery will lose 3%, while the other 2% where as without the grip it just 3% for the single battery. Which I didn't think that the 2% battery might be a normal discharge if left out of the grip. Didn't think of that I'll test that also!

Thank you!

I don't think so. I'm not 100% confident so I save network settings for our bodies as well. This should be checked (I could be wasting my time).

I'm just trying to ascertain if this is a battery condition or something the body is doing.

I can't say I've noticed what you are experiencing but I can test. I am assuming your storage location for body and batteries are not in some unusual environment?

My office is mostly around 21C, 60%Rh but varies a bit with people mulling around. I can simulate in one of the chambers but I will charge some batteries, two in a grip, one on the desk. (Canon batteries).

I'll do the same with some 3rd party night after.

We shall see what we see.

Anytime - always like a puzzle.

You asked where I store the camera. It's in my bedroom walk-in closet. Temp range would be controlled, 65 low for the night 72/74 during the day. Humidity about 45%.

Ok, I left the batteries in the camera with the grip mounted. I've checked the batteries every day for 6 days with the following results;

Both batteries were 100%

After;

Day1 96% and 97%

Day2 94% and 95%

Day3 94% and 93%

Day4 94% and 93%

Day5 93% and 92%

Day6 92% and 91%

At the same time that I charged the set of batteries reported above, I charged another set of batteries. All 4 are Canon LP-E6P batteries from B&H, each in it's own sealed box. All charged in the same charger to 100% all placed in the grip and measured using the R5MKII. One set above and other left until today.

The control set is now at 96% and 97%

Seems to me then, that in that amount of time, it would be normal to lose 3 to 4% of the original charge on a LP-E6P battery.

Also it means that leaving the batteries in the camera/grip does deplete them further, On average for this little test a little less than 1% per day!

I'm not a expert on batteries so I don't know if this is either good or bad, but at least I know how much batteries will be depleted leaving them in my camera over time.

I also assume that Support was correct in saying that they didn't think there was something wrong with my camera given that the manual does have a warning to remove your batteries overnight. Also 1%/day does not strike me as excessive! But others with expertise may differ!

Thanks for your help and the suggestion to test this out.
