Nikon has advised of problems occurring with certain EN-EL15 rechargeable lithium-ion batteries. To find out if your DSLR or Nikon 1 V1 camera battery is affected, you’ll need to look at the lot number on the label affixed to your battery.
If the 9th character of the lot number is E or F, your battery is among those being recalled.
And it’s only the battery that’s being recalled, not the camera, too.
If you think you’ve got one of the recalled batteries, go here.
