Having had a older DSLR model D3100 and a couple of batteries for it, I now have the newer D5300 and the battery spec for it is different, by a small amount. The older battery is EN-EL14, output 7.4v and 1030 mAh power rating, whereas the newer one, EN-EL14a, is 7.2v and about 1230 mAh. Both are identical in size and fit.
Unless someone has a good explanation to the contrary, I will take the position that they are interchangeable.
I am not a Nikon user, but they are probably interchangeable - however, the people to ask before risking it are Nikon, as 7.4 into 7.2 may not go. I f there was a problem then Nikon should have made the fit different (note I said should have).
