Safe and easy ways to recycle batteries

According to the Environmental Protection Agency, Americans buy nearly 3 billion dry-cell batteries every year (as of August 2008); the New York State Department of Environmental Conservation (DEC), puts it at 4 billion, as of this year. The EPA recommends recycling all types of batteries - though it's not required by all states. Years ago, most batteries were toxic, containing mercury and other chemicals. In the mid-nineties, the U.S. began phasing out mercury-based batteries of all types, so newer batteries don't pose the same risk of leaching chemicals into the soil at the garbage dump. Still, it's good practice to recycle - and manufacturers and retailers have made it easier. 

Rechargeable vs. non-rechargeable batteries

The DEC recommends using rechargeable batteries whenever possible, since you'll need to replace them less often. There are a few options for recycling (non-alkaline) rechargeable batteries, including lithium ion batteries (those in digital cameras and cell phones). You can also recycle button-style batteries (watch batteries), which do contain heavy metals, including mercury.

Where you can recycle batteries

The Rechargeable Battery Recycling Corporation, a non-profit organization backed by battery manufacturers is a good place to start. The site's Call2Recycle program offers a recycling location finder where you can input your zip code to find a nearby drop off site -- typically a retailer like Rite Aid or Radio Shack. You can also recycle by mail (for a fee) with Battery Solutions.

Where to find more information

AtBatt.com and the DEC website have helpful recycling charts, categorized by battery type. Call2Recycle offers information on recycling laws by state. Finally, About.com's guide to environmental issues offers advice and links about battery recycling. (Note: About.com owns ConsumerSearch, but no editorial affiliation is shared)
