B&H is replacing 15B batteries: B&H is replacing a batch of Nikon EN-EL15b batteries - Nikon Rumors Curious that there is no word from Nikon which would indicate a manufacturing issue and a system wide recall. I remember the early 15's wouldn't work when the D500 came out, and Nikon would exchange the older ones for current ones. The 15B's have been discontinued as noted in a previous thread but this seems unrelated. Speculation on my part, but maybe B&H got a batch of frauds??
