Environmental Concerns NiCad Computer Batteries Nickle-cadmium batteries are well established, but environmental concerns about the effects of their disposal hasten the availability of nickel-metal hydride batteries and other battery chenistries. Experts believe that NiCad batteries disposed of in landfills are breaking down and leaking cadmium, which is a toxic metal, into groundwater. Minnesota recently implemented legislation to address this problem. It forces battery manufactures and manufacturers of products that use NiCad batteries to make them easily removable from products so that they can be discarded separately. Minnesota has also mandated collection programs for NiCad batteries. Other states are expected to follow suit. California, Florida, Michigan, New York, Oregon, Connecticut, Florida, Illinois, Rhode Island, and Vermont are considering or have passed legislation that make NiCads easier to remove and dispose of. Some battery manufactures (including Compaq, Tandy,Toshiba, and Sharp) and their customers have formed a consortium called the Portable Rechargeable Battery Association. (PRBA), whose goal is to slow down the pace of change in battery regulation so that manufactures can keep up with the legislative demands. The PRBA was also formed to help users find ways to dispose of NiCads properly. If you have NiCad batteries to discard, contact the manufacturer of your product. Somr companies, such as DELL Computer, have already offered to collect NiCad batteries from customers at no charge. And Compaq Computer has started a recycling program for its NiCad battery packs.
