Different batteries have different recycling requirements.
Note: Nickel Cadmium (NiCad) rechargeable batteries, unlike single-use batteries, contain heavy metal elements that allow them to be recharged over and over. The heavy metals can be hazardous to the environment, unless they are properly recycled. They are categorized as hazardous waste.

These batteries may contain zinc, lead, mercury, nickel, cadmium, silver and electrolytes. If batteries leak or explode, the chemical substances contained in these batteries can cause internal and external burns and irritation. These batteries also contain heavy metals, such as lead, mercury, lithium, manganese, silver, zinc, cadmium, and nickel which can accumulate in ground and surface water, wildlife and humans when disposed of improperly.
Watch and Hearing Aid Batteries
Some local jewelers take back watch batteries for recycling, and some hearing aid clinics accept hearing aid batteries.
You will need to tape these batteries in order to have them recycled. Please use clear tape, like packing tape. The easiest way to do this would be to lay a piece of packing tape on a flat surface with the adhesive side facing up. Place these batteries on top the tape. Then press another piece of packing tape (adhesive side down) on top of the batteries. Press it firmly to create little individual packets of batteries on the strip of tape.
