(yes thay are all the same make and model) And they are recognized, and data shows correctly. But ONLY for the first two!</P><P>&nbsp;</P><P>What am I doing wrong? Or NOT doing right ?</P><P>&nbsp;</P><P>Thank you</P> Wed, 09 Oct 2019 23:21:28 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/EOS-7D-Battery-registration/m-p/283416#M64227 archellas 2019-10-09T23:21:28Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/EOS-7D-Battery-registration/m-p/283418#M64229 <P>Are these Canon batteries or 3rd party?
