Some important news for anyone who bought a Nikon D800 or D7000 DSLR earlier this year. The US Consumer Product Safety Commission and Health Canada announced today that the battery packs sold with the cameras are part of a voluntary recall due to a potential burn hazard. While there's been no injuries reported, Nikon says it has received seven reports outside of North America of the battery packs overheating, which can cause them to melt and pose a risk to users. The recall encompasses 5,100 batteries in the US (sold in March and April) and 1,100 in Canada (sold in February and March), plus an additional 195,000 battery packs worldwide. Those with one of the battery packs in question are advised to remove it from their camera and contact Nikon directly for a free replacement. Complete details can be found at the source link below.
Update: As some have pointed out in comments, Nikon first initiated this recall itself in April, but it has just now risen to the level of the CPSC and Health Canada.
