I have always run the battery completely down before changing. When I am shooting and it runs down I swap to the spare. When I get home I charge the battery and put back in the camera bag. I read it is not good to fully charge a battery and store it?  My D850 has a feature in the menu that will show the precentage of life and the age of battery. I had run down the battery that came with the camera and swapped to the spare. It ran down in 2 weeks of working in the menu while reading the book and testing. When I was going to swap to the original charged battery, I mistakenly put the charged battery in the charger. It had blinked about 2 times when I realized my mistake, I swapped the batteries putting the charged on in the camera. I do not know, but have assumed the charger was draining the battery before / while do the re-charge. Do not know if that is true, but even if it is , only 2 blinks should not do much drain. When I put the recharged (sitting for 2 weeks) in the camera I checked the percentage, 94%, so it drained 6 percent over a 2 week period? So in a months time it could be in the 80%. For me I would not like to leave a dead battery in the bag and chaged the day of needed. I want the spare to be ready when I have a chance to go take pictures. 

Also the top display never goes off on the D850, I realize that screen does not use much battery , but I am sure it will over time. Do not see a way to turn it off when the camera is turned off. 

How do you maintain you batteries?

Looking at the cool pictures Marcus posted of his moon shot brought this to mind.

Last Saturday just as I pulled off the highway on top of a hill to wait on the sun to set, my son sends a text saying he is sitting on the beach waiting on a Full Moon to rise. He is on East cost of Fl, way down near Miami , 1 hour ahead of me in Al. We swapped pictures in text, this week we were talking about how the sun was almost down and the moon just above the horizon was kinda cool. I looked at the times on the pictures, it was actually 2 minutes different when we were taking the pictures or it seems that way to me,

I am reading another book on my D850, looking at settings in the camera as I read. 

I had the XD card as Main = Raw and SD card as second = Jpeg , writing to both at the same time. At some point when I was reading and looking I changed to XD Main and SD as overflow. So today I am taking sunset pictures, when reviewing I notice todays pictures are not on the SD / jpeg card. Had a couple of pictures that turned our fair and wanted to send to my phone. I remember reading about doing the Raw files to Jpeg in the camera. I did not pay much attention to it as I figured it would be better to do on the pc (when I get all that setup) . So for a couple of pictures the in camera conversion might be good. When I go to the NEF Raw and then click the Selector to the Right, I get error "No image for retouching" . If I choose Trim or any of the  others below and move to the Right it goes to the pictures to select from. I can scroll through todays pictures on the XD card so I know they are there. Any ideas why this is showing the error?

Thanks

Reading in a book about the Custom Settings Bank A/B/C/D , seem to make sense, I "think" I understand what they are used for. I setup A as "General Purpose" and made some setting changes that I assume were under it. Tonight I notice in pictures that I was taking here in the house testing that when I preview them they had a lighting bolt with arrow on both ends. Could not find what I did to cause that so I read how to Delete the custom A that I had done. When I delete it , the name General Purpose is still showing, so I don't know did it really setup back to default and leave the custom name I gave it? The lighting bolt was still on the pictures so either it did not delete the Custom A or it was something else.

I did find how to remove the lighting bolt from the preview , somehow I had set the "send to smart device" to On, set to Off, lighting bolt is gone.

Still don't know if I have deleted the Custom settings I did under A Bank.

Yesterday I was testing my D850 with my 18-140mm DX lens. Sun was below the horizon when I got to my spot , however some nice orange clouds. Took a few pictures, as it got darker I change to S mode and slowed the shutter down just a little, I could still hold with my hands. The view finder showed the small square showing the DX area, but also showed a dark circle around the area. Pictures came out gook, just have never seen the dark circle. What is that?

Thanks
