The Nikon EN-EL15 battery has been used in most of Nikon’s mid-range cameras since the release of the D7000. It’s still used in many of today’s popular Nikon DSLRs including the D500, D610, D750 and D810. Now Nikon have issued a voluntary recall on the EN-EL15 battery. It’s due to a short circuit that may potentially cause them to overheat and melt.
Now, don’t worry, your cameras probably aren’t likely to turn into a Galaxy Note 7. Nikon say that there only 7 confirmed incidents worldwide, so far. So, this is a voluntary recall. But, if you do have an affected battery, it sounds like it’s worth sending it in.
