EOS R5 Mark II doesn't show fully-charged batteries as full

[KirstineWalton]

I have two r5 mkii bodies and 4 original batteries. I’m charging the batteries to full and then when I put them in the cameras they only show as 2 bars charged. I’ve updated the firmware and it’s still doing it. Any ideas what’s going on? Both the cameras and the batteries are not even a year old.

@KirstineWalton so you are talking about recharge performance NOT battery percentage.

[KirstineWalton]

I’m talking about the battery charge in the corner of the display that shows as a bars. I just included this photos in case it helped answer whether my charger was working or not

@KirstineWalton I have 2 pictures below to understand your problem. Is it the picture with the item circled in red or blue.

Please call support at 1-800-OK-CANON (800-652-2666). They will help.

Neither of those. When you look through the view finder, there’s a battery icon in the bottom right corner. That is the one I’m talking about. 
I uploaded those images just to show battery health

@KirstineWalton is the camera actually dying while in use like a dead battery or not. Every camera is different and the battery icon may NOT be as detailed as the one in the camera menu. It may be only able to show 2 bars. How old are these batteries by any chance.

[KirstineWalton]

I haven’t pushed them to find out if they die as it’s been when I’m shooting an event so have taken them straight out and plugged them in again. The oldest two are a year old, other two I bought in December. Haven’t worked out which it is yet. Trying to narrow that down. 
I get it might not be accurate but to take them from fully charged in a charger to immediately putting them in a camera and it’s showing up as 2 bars not 4 - that’s not right!

Why are you not willing to try charging them in the camera to see if it makes any difference?  Seems that might be a data point worth exploring to me.

[KirstineWalton]

Not sure where I’ve said I’m not willing to try that…. I’ve been explaining what I’ve done so far. Don’t have a cable on me to try that right now and they are currently showing fully charged again. I will try it when I have the cable and the flat batteries to try it 

[SignifDigits]

You're correct.  You didn't say that.  My apologies.  You just make the correct point that it couldn't be a bad charger.  Seems worth a try.  I'm just wondering is there is some camera logic that is metering them as not 100% charged but will if it's been the one charging them.  That shouldn't be true, but if all the shouldn'ts in the world came true we'd be in a very different world that what we are now.
