Do not put lithium batteries in the trash or curbside recycling bin. Federal guidance from the EPA directs households to tape terminals and drop batteries at household hazardous waste sites or authorized recyclers, while businesses must decide whether to manage them under universal waste or hazardous waste rules. Damaged batteries need special transport permits before anyone moves them.
TL;DR:
- Households must tape terminals and drop lithium batteries at hazardous waste sites or authorized recyclers to prevent fires during transport.
- Businesses need to follow strict hazardous waste regulations, including proper storage, characterization, and transportation permits, especially for damaged or recalled batteries.
- Damaged or swollen batteries require immediate isolation, specialized handling, and transport under DOT permits with fire-suppressant packaging to avoid fire risks.
- Recycling processes start with discharging and shredding batteries into black mass, which yields metals like lithium, cobalt, and nickel for recovery, but facilities may refuse damaged packs.
- Local and state rules vary, so it is crucial to confirm disposal options such as retailer take-back programs and stewardship schemes before dropping off any lithium batteries.

How to prepare lithium batteries and where to take them
Lithium batteries catch fire when their terminals touch metal, another battery, or each other. That is why the EPA recommends isolating each battery before it ever leaves your house or office. The steps are simple, but skipping them is the most common cause of waste-truck and recycling-center fires.
- Cover both terminals with non-conductive tape, such as clear packing tape or electrical tape.
- Place each taped battery in its own plastic bag, separate from other batteries and metal objects.
- Store bagged batteries in a cool, dry spot away from anything flammable until you can drop them off.
- Confirm your intended collection site accepts the battery type and size before you make the trip.
Once batteries are isolated, your drop-off options include:
- Municipal household hazardous waste (HHW) collection sites or events.
- Retailer take-back programs, many of which use Call2Recycle collection boxes; call ahead to confirm they accept your battery type.
- Authorized battery recyclers listed through local waste authorities or state recycling directories.
What you should never do: never place lithium batteries in curbside trash or recycling, and never puncture, crush, or try to disassemble a battery yourself. A cell that looks dead can still hold enough charge to spark a fire. If you are clearing out old laptops along with their batteries, preparing laptop batteries for recycling the right way keeps both the device and the battery out of the waste stream safely.
Pro Tip: Keep a small role of clear packing tape near wherever you store old electronics. Taping terminals the moment a battery comes out of a device is far safer than trying to remember later.
Business and generator rules: RCRA, universal waste, and handler obligations
Businesses face a stricter set of rules than households, because a company generating used batteries is legally a hazardous waste generator, not a curbside customer. The EPA’s lithium-ion battery FAQ states that many lithium-ion batteries are likely hazardous waste at the end of their life, often triggering ignitability (D001) or reactivity (D003) characteristics.
Many lithium-ion batteries meet hazardous waste characteristics at disposal, according to the EPA, which is why the agency recommends businesses manage them under universal waste standards (40 CFR Part 273) or full hazardous waste rules rather than assuming ordinary trash disposal is acceptable.
Key obligations for business generators include:
- Determining whether your facility qualifies as a Very Small Quantity Generator (VSQG), a threshold tied to generating very small amounts of hazardous waste in a calendar month.
- Storing batteries in closed, non-conductive containers labeled to identify the contents and accumulation start date.
- Keeping batteries intact rather than disassembling battery packs, unless cell casings remain undamaged, as allowed under universal waste handler rules.
- Sending accumulated batteries off-site within the timeframes set by your handler category.
- Checking your state hazardous waste program, since states can impose rules stricter than the federal floor.
An organization that treats used batteries the same way it treats used paper is taking on legal and fire risk it likely has not budgeted for. A written disposal plan for business electronics removes the guesswork and gives your team a repeatable process auditors can check.
Transport and shipping rules for damaged and undamaged batteries
Once a battery needs to travel, whether across town to a recycler or across state lines to a processor, DOT and PHMSA hazardous materials regulations under 49 CFR govern how it must be packaged, marked, and shipped. These rules exist because a battery that short-circuits in transit can ignite cargo that firefighters cannot easily reach.
- Standard shipments of undamaged batteries require UN-rated packaging, terminal protection, and specific hazard markings.
- Damaged, defective, or recalled batteries cannot move under normal shipping rules at all.
- PHMSA special permits such as SP21970 authorize one-way transport of damaged lithium-ion batteries, but only in UN-specified packaging filled with a silica-based fire suppressant, and often restricted to highway transport only.
- Some permits, including filings like SP21383, add driver emergency procedures, minimum trailer ventilation, and placarding requirements on top of standard packaging rules.
Special permits specify UN packagings, silica-based fire suppressant filling, package limits, highway-only transport, and required markings and emergency contact information.
PHMSA Special Permit SP21970
Air transport of damaged lithium batteries is effectively off the table, which is why highway-only special permits exist. Before offering any battery for transport, an organization needs certified packaging, trained personnel, and documented emergency procedures. Skipping this step is not a paperwork technicality: it is the difference between a compliant shipment and a hazmat violation.
State rules and stewardship programs differ by location
Federal rules set the floor, not the ceiling. Some states ban lithium battery disposal in household trash outright, require retailers to take back batteries they sell, or run dedicated battery stewardship programs funded by manufacturers. A rule that applies in one state may not exist in the next, so a national organization with multiple locations cannot rely on a single national policy.
- Check your state’s solid waste or environmental agency website for battery-specific disposal or recycling requirements.
- Use the EPA’s battery collection resources to find best practices adopted at the state and local level.
- Confirm whether your state runs a battery stewardship program, which typically funds free collection through participating retailers.
- Ask your municipal HHW program directly whether it accepts lithium batteries year-round or only during scheduled events.
Retailer take-back programs vary by chain and even by location within the same chain, so a quick phone call before you drive across town saves a wasted trip.
Handling damaged, swollen, or recalled batteries safely
A damaged, swollen, or recalled lithium battery is not a disposal problem, it is a safety incident waiting to happen. Treat it accordingly.
- Move people away from the battery and isolate it from anything flammable, but do not move a battery that is actively smoking or venting.
- If a fire starts, use a Class D or ABC-rated extinguisher designed for the situation, and call emergency responders immediately for anything beyond a small, controlled flare.
- Do not attempt to de-energize or stabilize a swollen or leaking cell yourself. This is a job for trained hazmat responders or certified recyclers with the right equipment.
- Once stabilized, transport only under an applicable DOT special permit using UN packaging filled with silica-based fire suppressant, restricted to highway-only movement, with the required hazard markings attached.
Large-scale incidents, such as a fire at a storage or processing facility, can escalate into EPA-overseen cleanup actions that involve on-site sampling and months of documented remediation before any material can move again. That scale of response underscores why damaged batteries deserve isolation and expert handling from the first minute, not shortcuts.
Pro Tip: If a lithium battery feels hot, looks puffy, or smells sharp and chemical, stop handling it and call your local fire department’s non-emergency line for guidance before you do anything else.
What happens to lithium batteries once a recycler receives them
Recyclers do not just toss batteries into a bin. The process typically starts with an evaluation of battery type and condition, followed by discharge to remove remaining energy before any mechanical work begins. From there, batteries are shredded, producing a mixed material called black mass, which then goes through hydrometallurgical or pyrometallurgical processing to recover metals like lithium, cobalt, and nickel, according to EPA recycling guidance.
- Discharge and shredding are common early steps, and the resulting black mass is the feedstock for later metal recovery.
- Many shredding operations qualify for exemptions from hazardous waste treatment permitting, but storing hazardous residues on-site can trigger RCRA Part B permitting requirements.
- Not every recycler accepts every battery. Damaged cells, large-format packs from electric vehicles, or unidentified chemistries may be refused by facilities without specialized handling capability.
That last point matters for anyone choosing where to send batteries: a facility that turns away damaged units is not being difficult, it is following the same packaging and permitting constraints outlined earlier.
A practical checklist for vetting a compliant recycler
Before handing batteries to any recycler, verify a few basics and keep the paperwork that proves you did.
- Confirm the recycler holds a valid EPA identification number and, if it stores hazardous residues, a RCRA Part B permit.
- Ask for written procedures covering damaged or swollen batteries, not just standard intact units.
- Request a certificate of recycling or destruction for every load, not just large ones.
- Keep manifests, receipts, and certificates on file in case of an audit.

How UsedCartridge approaches compliant lithium battery handling
UsedCartridge operates as an environmental services provider focused on e-waste recycling, data destruction, and IT asset recovery, built around compliant and environmentally responsible disposal rather than a drop-and-forget model.
- On-site destruction and official certification may be offered for secure data destruction and e-waste disposal, helping to document compliance with environmental and data privacy requirements.
- Proper procedures often address handling for damaged lithium batteries and other hazardous materials found in electronic waste, rather than treating every battery as a standard case.
- The emphasis is often on compliance paperwork that holds up during an audit, beyond just collection of waste bins.
For an organization that needs to show its work, that combination of process and documentation is the actual product, not an afterthought attached to a pickup.
Why compliance and recovery reinforce each other
Following EPA, DOT, and state rules is not just about avoiding a fine. A battery handled correctly from the first tape strip to the final recycler cuts the odds of a fire at a transfer station, a truck, or your own loading dock, and that is a liability question as much as an environmental one.
There is also a recovery angle that gets lost in the compliance talk, especially considering the e-bike fire risks in UK flats and the urgent duties for responsible persons. Every battery that goes through a proper discharge and shredding process instead of a landfill contributes lithium, cobalt, and nickel back into the supply chain instead of losing it permanently. Compliance and material recovery are not competing priorities, they are the same process viewed from two angles.
Organizations that build a real SOP, one that covers intact batteries, damaged batteries, and documentation, spend less time reacting to incidents and more time simply running their operation.

FAQ
Is it legal to throw lithium batteries in the trash?
No. The EPA advises against placing lithium batteries in household trash or curbside recycling, and many states legally prohibit it outright. Take them to a household hazardous waste site, retailer take-back program, or authorized battery recycler instead.
What is the 80/20 rule for lithium batteries?
There is no federally recognized rule for lithium battery disposal involving percentages; for disposal, follow EPA guidance: tape the terminals, bag the battery, and take it to an approved collection site.
Can I drop off lithium batteries at Lowe’s or Home Depot?
Many major retailers participate in battery take-back programs, often through Call2Recycle collection boxes, but participation and accepted battery types vary by store and location. Call ahead or check the retailer’s website to confirm your local store accepts your specific battery before making the trip.
What should I do with a swollen or damaged lithium battery?
Isolate it from flammable materials immediately and do not attempt to move it if it is smoking or venting; call emergency responders for any active fire or venting event. Damaged batteries require specialized transport under DOT special permits with fire-suppressant packaging, so contact a certified recycler or hazmat responder rather than shipping it yourself.
Are businesses subject to different lithium battery disposal rules than households?
Yes. Businesses generating used lithium batteries are treated as hazardous waste generators under EPA guidance, which recommends managing them as universal waste or hazardous waste depending on generator status and state rules, rather than as ordinary trash.
