Waste lead-acid batteries are classified as hazardous waste under national regulations (hazardous waste code HW31) and contain toxic and harmful substances such as lead and sulfuric acid. If disposed of indiscriminately or forcibly dismantled, they can cause irreparable contamination of soil and water resources and pose serious risks to human health. Therefore, they must never be treated as ordinary household waste. As an individual consumer, you can dispose of waste lead-acid batteries through the following safe and compliant channels:

Trade-in for a new one (most recommended and most convenient)

If you’re replacing the battery in an electric bicycle or a car, the most straightforward approach is to have it collected by the dealer or an authorized service center. Under the Extended Producer Responsibility system—“the producer is responsible for recycling”—electric-bike and automobile retailers, as well as various repair shops, typically offer a “trade-in” service, whereby they will take back your used lead-acid batteries and handle their proper disposal or recycling.

Hand over to a professional recycling agency

If you do not yet need to replace the battery or have unused, discarded batteries on hand, you may contact and deliver them to an entity licensed to handle hazardous waste for centralized disposal. You can find a list of authorized recycling companies on the website of your local ecological and environmental bureau, or consult your local environmental protection authority to obtain information on legitimate recycling channels.

Prohibited Conduct and Legal Risks

Strict prohibition on careless disposal: Waste lead-acid batteries must not be mixed with ordinary household waste or discarded indiscriminately on roadsides or in wilderness areas.

Strict prohibition on unauthorized disassembly: Under no circumstances shall battery lead plates or acid be dismantled and resold for profit.

Strictly prohibit handing over to unlicensed vendors: Do not sell used batteries to itinerant collectors or other illegal recyclers who operate without a hazardous waste management license.

Special reminder: The illegal collection, transportation, and disposal of waste lead-acid batteries constitute unlawful conduct. According to relevant laws and regulations, the illegal discharge, dumping, or disposal of hazardous waste in quantities exceeding a certain threshold (e.g., three metric tons or more) not only incurs substantial fines but may also amount to a criminal offense, subjecting the offender to criminal liability in accordance with the law.

Daily Safety Tips for Temporary Storage
Before handing in used batteries to a recycling collection point, please observe the following safety precautions:
Keep the battery casing intact: Do not squeeze or drop the battery to prevent damage to the casing and subsequent acid leakage.
Store upright: Place the battery vertically in a cool, dry location, avoiding tilting or turning it upside down.
Preventing short circuits: Wrap the battery’s positive and negative terminals with insulating tape to prevent accidental short circuits that could pose a safety hazard.
