While an uncharged CR2477 is considered non-hazardous and safely can be disposed of in municipal waste, we strongly recommend taking it — and all other batteries! — to a local recycling center, household hazardous-waste disposal facility or universal waste handler. Most retailers that sell these batteries also have a recycling program in place.
Proper disposal of batteries is important to avoid exposing the environment (lake, streams, landfills) to potentially dangerous metals.
