All batteries contain heavy metals, which are useful for providing power for our portable devices, but aren’t so great for the environment. When your batteries run out of juice, or just won’t keep their charge anymore, be sure to dispose of them properly.

Many small electronics, like cell phones, iPods, computers and digital cameras use rechargeable batteries. These are often nickel-cadmium, metal-hydride or lithium-ion batteries. Then there are single-use alkaline batteries used for remote controls, alarm clocks, and other small devices. And of course there are the big lead-acid batteries that sit under the hood of your car. (For more on different battery types check out Earth911.org.)

Don’t throw batteries away. When the battery casing corrodes in a landfill, the heavy metals leak out and contaminate soils and groundwater creating a real toxic mess. This is why batteries (and other electronic items containing heavy metals) should be disposed of safely. While recycling batteries isn’t as easy as recycling a soda bottle, it is easy to find a place to drop them off.

A drop off site may be closer than you think. Many hardware stores, drug stores, and electronics retailers now act as collection points for batteries. Call 2 Recycle, a rechargeable battery recycling corporation, lists small and large retailers that offer this service to customers. You can also find battery drop-off locations near you at Earth911.org. For car batteries, check with your local auto shop or solid waste management company for safe disposal details.

Amy says: When my AA batteries die I’ll throw them in a drawer that holds some other electronic odds and ends (but you can use any kind of container). Once I’ve built up a stash of used-up batteries, I take them to my locally-owned green retailer, 3R Living. They collect the batteries and send them off to a company for recycling or safe disposal.
