[Leica] Leica blocking 3rd party batteries in firmware?

[j2m46 at hotmail.fr (Jean-Michel Mertz)]

Hello Kyle, I'noticed that third party Leica batteries shut down though 
they're fully charged - same as you. I then switch the camera off and on ... 
and the battery is ready to work! It seems to me these batteries do not 
activate the full battery gauge on the camera body until they are empty and 
the camera is re activated, to signal the battery that a new session is on 
and that it should now use what it's been loaded with. This works with my M8 
body but may not apply to the M9.
