ALKALINE, LITHIUM, BUTTON, AUTOMOTIVE
Single use Alkaline and Carbon-Zinc Batteries (AAA, AA, C, D, 6V, 9V) are wasteful, but not hazardous. Dispose with trash. If your trash goes to Covanta SEMASS, the metal is recovered.
All non-alkaline batteries contain hazardous and/or valuable materials.
Since it takes about 50 times more energy to make a battery than you get out of it, it is better to use Rechargeable Batteries.
Call2Recycle provides the collection boxes at many retail and municipal locations for batteries commonly found in cordless power tools, phones, laptop computers, digital cameras, and remote control toys:
Nickel Cadmium (Ni-Cd),
Nickel Metal Hydride (Ni-MH)
Nickel Zinc (Ni-Zn)
Lithium Ion (Li-ion) but NOT Lithium. Seal spent lithium batteries in a dry plastic bag and bring to Hazardous Waste Collection Event
Small Sealed Lead** (Pb)
Find locations near you here.
Your town may have also a Call2Recycle collection box at its transfer station or recycling center.
Most small, round batteries found in items such as watches and hearing aids contain mercury, silver, cadmium, lithium, or other heavy metals.
If your jewelry store doesn't accept them for recycling, bring them to a Hazardous Waste Collection Event.
Automotive and Small Sealed Lead batteries are banned from disposal due to their lead content, and may have some scrap value.
Many municipal transfer stations and recycling centers accept automotive batteries for recycling.
Scrap metal dealers usually pay a few dollars for them if delivered to their facility.
In conjunction with Earth Day (April 22), AAA holds their Great Battery Roundup with multiple collection points.
