watch Help! The internal battery on my Nikon F6 seems to be dead!
So you just bought a new used Nikon F6 35mm film camera, and the internal battery seems to be dead. Don’t panic. Simply insert new batteries and allow 48 hours and the camera’s internal battery should recharge and allow you to do things like set the date, use the intervalometer and all the other things that camera relies on that tiny, inaccessible but super important item for.
