Hi I use two battery original Sony battery and 2 Patone battery with Sony a7r4 with latest firmware Except that a message comes that are not original battery, I have found no differences.
I can't tell you if the battery is charged correctly, but in a whole day of photo reportage (only photos) I need 2 batteries, and I always use them alternately...
No, but why would you want to risk the battery in the expensive camera being inflated because of the small price difference, as happens with such cheap replica batteries?
