Nikon has recently recalled battery packs sold in its Digital SLR Cameras due to a defect causing it to short circuit. The packs pose a significant burn injury risk, as the problem will cause the packs to overheat and even melt. To date, there have been seven incidents of the packs overheating, but no reports of any injuries. If you own a SLR D800 or D7000 camera, check the serial number of the battery pack. If the ninth character is not an “E” or an “F”, then your pack is not part of the Nikon recall.
