Q: 1. Would this work with the Nikon Z7II? I tried to use the Watson EN-EL15/b and you get an incompatibility error - firmware probably. The latter battery does work with the Nikon D7100.

Q: 2. I have noticed that the charger (DLC) displays different battery capacity depending on charging bay used: right and left. For example: same battery shows 100% capacity when tested in the right charging bay but it shows only 95% when it tested in left charging bay. It means the left bay will never give a 100% capacity? What is the reason for this inconsistency?
