I've had a look here and see some conversation in 2022 about changing battery designation from left and right to 1 and 2.  And some promises about Ring fixing this.   I am a new user of camera pro and I can't work out which battery of the two is the one that needs to be recharged.  They are still designated 1 and 2 in my android app. 

Obviously a solar panel should solve this problem to a degree but meantime, I only have so much money to spend so am building my system when I can.  Additionally I'd like to start using my solar panel with fully charged batteries, so either way I need to know which is which. 

Help please.
