Where to Recycle Your Batteries

Recycling of non rechargeable batteries is still somewhat rare, but recycling used RECHARGEABLE household batteries is now possible! The battery manufacturers have funded a joint recycling center. To find a center near you that will take them, click here! (in the US or Canada))( Which types do they take? Nickel Cadmium (Ni-Cd), Nickel Metal Hydride (Ni-MH), Lithium Ion (Li-ion), and Small Sealed Lead* (Pb) rechargeable batteries are commonly found in cordless power tools, cellular and cordless phones, laptop computers, digital cameras, two-way radios, camcorders and remote control toys.
Note that California is a bit of a special case. California regulations require recycling for more types of batteries than other states. See this page for detailed information about how and where to recycle batteries in California.

If you can't find a location above:
Take the rechargeable batteries to any of the participating retailers. In the U.S.: Alltel, Batteries Plus, Best Buy, Black & Decker, Cingular Wireless, The Home Depot, Milwaukee Electric Tool, Orchard Supply, Porter Cable Service Center, RadioShack, Remington Product Company, Sears, Staples, Target, US Cellular, Verizon Wireless, and Wal-Mart. And in Canada: Battery Plus, Bell Mobility, Canadian Tire, FIDO/Microcell, Future Shop, The Home Depot, Home Hardware, London Drugs, Makita Factory Service Centers, Personal Edge/Centre du Rasoir, RadioShack Canada, Revy, Sasktel, Sears, The Sony Store, Telus Mobility and Zellers.
Use the RBRC collection site locator, or call the consumer helpline, 1-800-8-BATTERY, to find the retail collection site nearest you.

Non-rechargeable (typically "alkaline batteries") still don't have a recycler and general just must be disposed in the trash. If you have large quantities or are a business, talk with your permitted sanitary landfill operator (otherwise known as "sanitation services", the "dump" or "landfill"). Waste batteries should not be burned because of the metals, and they could explode. When burned, some heavy metals such as mercury may vaporize and escape into the air, and cadmium and lead may end up in the ash.
