Garmin Rally Power Meter Pedals: Look Road, Shimano Road & MTB

I’m having an issue with the left pedal of one of my sets: It shows low battery (on the 1040, and garmin connect), even after swapping with new CR1/3N batteries (tried 3 new ones, same kind I’ve always used, and double checked they are outputting 3V) .

Is there a fix other than replacement?

I am running sofware 4.1
