Best Battery Choices

Dear Co-op America, Please settle an argument between my wife and me. Which rechargeable batteries are better for the environment: NiCads (my pick) or NiMHs?

— Joe and Jessica, Milwaukee,Wisc.

LOOKS LIKE your wife wins this time. Both nickel cadmium (NiCad) and nickel-metal hydride (NiMH) rechargeables can be recharged over 500 times, but the toxic cadmium in NiCads makes their disposal problematic. Instead of cadmium, NiMHs use metal hydrides, which are less harmful to the environment. (Both are, of course, much more eco-friendly than single-use alkalines, as they last a lot longer. They also outperform rechargeable alkalines, which can only be recharged 50 times.)

Performance-wise, NiMHs have an edge over NiCads, too, with their lower discharge rate. Over 60 days, NiMHs on a shelf will experience 15 percent energy loss, compared to NiCads, which will lose 60 percent.

Because of their long life, less-toxic innards, and solid performance, NiMHs are your best bet for most uses.

When it’s time to dispose of dead batteries, be sure to recycle them. If your local recycler doesn’t accept batteries, Battery Solutions (800-852-8127, batteryrecycling.com) will recycle your used alkalines and rechargeables. You do have to pay a small fee, with discounts for large quantities.


DEAR CO-OP AMERICA, Do you know where I can find eco-friendly clothes for older kids? Everything I’m finding seems to be for babies.

— Concerned Mom in Kansas

WHEN IT COMES to outfitting growing children, nothing beats reuse in terms of saving money and resources. Swap with friends, and scour garage sales and secondhand stores for cheap, quality items. Online auction sites can yield bargains in bulk: enter your child’s size and gender on eBay.com’s search engine, for example, to find entire lots of nearly new clothes for sale.

When buying new items, look for children’s clothing made from eco-friendly fabrics, such as organic cotton, hemp, linen and wool, which are grown without chemical pesticides and fertilizers. The sheep from which organic wool comes are fed organic feed and are not treated with synthetic hormones or pesticides.

When shopping for organic fabrics, remember that federal organic standards only cover raw fiber harvesting. Once the organic fiber leaves the farm, there are no standards preventing it from being treated with chemicals later in the process, including bleaches, dyes, or finishers. Many clothing companies that belong to the Organic Trade Association (413-774-7511, ota.com) have embraced their voluntary production standards to minimize chemicals, and other green companies have enacted similar standards — be sure to ask before making a purchase.

Garden Kids (800-620-7388, gardenkids.com) and Green Babies (800-603-7508, greenbabies.com) are both members of OTA and offer organic cotton clothing for kids of all ages. Also, there are dozens of companies in our National Green Pages that offer eco-friendly children’s clothing. Visit green pages.org and search the clothing categories, or call us at 800-58-GREEN to get a paper copy for $11.95.
