I got myself an Nikon D80. I have a spare battery for it. EN-EL3e.
What I am fearing is. I don't use that battery and keep it as a backup. I will probably forget about it for days and charge it only when I go to a photoshoot or an event.
Is it really healthy to simply forget it inside a drawer and after days of not using it just charge it and go to a photoshoot with it?
I just fear an battery leak,self combustion,battery age drop or things like that.
So what is the best course of action for keeping spare Li-Ion batteries like that safe? Should I regulary charge it and take photos with it when its not in use and then put it back away in a drawer?
