Canon BG-R10 Battery Communication Issue


Hi All, I recently re-installed by BG-R10 grip onto my CanonR5 and I'm getting a battery communication error/"Is your battery a Canon" message. The grip worked well without any issues in the past. The battery is an authentic Canon LP6NH and came with the camera. If I insert the battery into the Camera, it is recognized. But, if it's in the grip, it thinks it not a Canon.

Has anyone else experienced this ?

Not sure if it's relevant but I updated to Firmware 1.60 before the battery grip was re-installed. 

Any thoughts on how to resolve ?

Thank you !

Hi aswilsonpvt,

I'm sorry to hear your BG-R10 is not accepting your batteries. Since the batteries aren't giving the message when they're loaded in the camera that indicates they are not the cause. The BG-R10 is compatible with an EOS R5 running the newest firmware, so that shouldn't be causing the issue either. 

There are a couple of things to try. The first is to try cleaning the battery contacts with a dry microfiber cloth, and to double check there aren't any obstructions in the camera battery compartment or on the part of the grip that goes into the battery compartment. Sometimes if the battery contacts aren't clean or if there's something like just in the battery compartment it can cause issues like this. 

If that doesn't resolve the issue one other thing to try would be to put the batteries on a charger and leave them overnight. Even if they are fully charged. Sometimes if they aren't providing power how the camera/grip expects it can cause this kind of message and leaving them on a charger overnight can help reset that.

If the issue continues at that point we would recommend sending the grip in for repair. 

Attached is a PDF repair form for you to complete and include with your unit when it is sent in for service.
