Proper disposal of old lithium-ion (Li-ion) and lithium-polymer (LiPo) batteries is important for both safety and environmental reasons. Here are the recommended steps for discarding these batteries:

**1. Do Not Throw Batteries in the Trash:

• Avoid Landfills: Lithium-ion and lithium-polymer batteries contain chemicals and metals that can be harmful to the environment if they leach into soil and water. Throwing them in the regular trash can pose environmental risks.

**2. Use Battery Recycling Programs:

• Recycling Centers: Many communities have designated recycling centers or electronic waste (e-waste) disposal sites that accept batteries. These facilities can properly handle and recycle the materials.
• Retail Take-Back Programs: Some retailers and electronics stores offer battery recycling programs or take-back schemes. Look for collection bins or contact the store for information on how to recycle your batteries.
• Municipal Collection Events: Check if your local municipality hosts special collection events for electronic waste or batteries.

**3. Follow Local Regulations:

• Compliance: Different regions have varying regulations and guidelines for battery disposal. Check local regulations to ensure you are following the proper procedures for your area.

**4. Prepare Batteries for Recycling:

• Tape Terminals: If possible, tape the terminals of the batteries to prevent short-circuiting during transportation and handling. This is especially important for lithium-ion batteries, which can pose a fire hazard if their terminals come into contact with each other or other conductive materials.
• Avoid Damage: Handle old batteries carefully to avoid puncturing or damaging them, which can cause leaks or fires.

**5. Special Considerations for Large Quantities:

• Bulk Disposal: If you have a large number of batteries, such as from a business or organization, contact a professional e-waste disposal service that can handle bulk quantities and ensure proper recycling.

**6. Battery Collection and Recycling Resources:

• Call2Recycle: In some regions, organizations like Call2Recycle offer battery recycling services and provide information on drop-off locations. Call2Recycle Website
• Local Recycling Programs: Search for local recycling programs or hazardous waste disposal services that accept batteries.

Summary:

• Do Not Throw Batteries in the Trash: Avoid landfills due to environmental risks.
• Use Battery Recycling Programs: Utilize designated recycling centers, retail take-back programs, or municipal collection events.
• Follow Local Regulations: Adhere to local guidelines for proper disposal.
• Prepare Batteries for Recycling: Tape terminals and handle batteries carefully.
• Special Considerations: Use professional services for large quantities of batteries.
• Resources: Check organizations like Call2Recycle for battery recycling information.

By following these guidelines, you can ensure that old lithium-ion and lithium-polymer batteries are disposed of in an environmentally responsible and safe manner.
