Battery Emergencies, Swollen Packs, and Safe Disposal

The volume ends with the section everything else exists to keep rare: what the bench does when lithium stops being routine. The territory reads as a ladder, and each rung has its own verbs. A swollen pack is stable trouble — the failure announcing itself politely — and its protocol is calm: no pressing, the fireproof container at sight, the photograph, the owner's call, the conversion the volume has drilled since the phone chapter. A venting cell is active trouble — hissing, the solvent-sweet smell, smoke without flame — and its verbs change: people move first, the plume goes unbreathed, ventilation opens, and the cell reaches containment only if that takes tongs and seconds, because no bench object is worth a lungful or a flare in the hand. A thermal event is the failure finishing — and honesty about what works: the fireproof container holds it, an extinguisher may knock down flame without stopping the runaway underneath, and water — used generously — does the one job it can actually do, cooling everything around the cell and breaking the chain to its neighbors, on lithium-ion though never on lithium-metal primaries, whose chemistry answers water with worse. Anything beyond a single small cell already in containment belongs to evacuation and emergency services, full stop. Then the aftermath the untrained skip: the reignition watch, because finished cells relight hours later; the fumes treated as the toxic mixture they are; the incident record that turns a bad afternoon into a process fix. And finally the disposal law that runs every quiet week: terminals taped the hour a pack retires, bagged, and out through the recycling stream — never the trash, because bin fires happen at the truck and the facility — with swollen and damaged packs taking the hazmat route in containment, and nothing damaged ever shipped by ordinary post. The chapter staged the equipment; this section is the afternoon it was staged for.

What You Will Learn

  • You will learn the escalation ladder — swollen is stable, venting is active, flame is the failure finishing — and the verbs that belong to each rung.
  • You will learn the swollen-pack protocol — calm, complete, photographed, converted — and the storage rules for packs awaiting disposal.
  • You will learn the venting response — people first, plume unbreathed, ventilation open, containment only if it takes tongs and seconds.
  • You will learn honesty about fire — what containment holds, what extinguishers do and do not stop, water's real job on lithium-ion and its danger on lithium-metal, and where evacuation and emergency services take over.
  • You will learn the aftermath and the disposal law — the reignition watch, the fume rules, the incident record, and every pack's taped exit through the recycling stream.

What You Will Be Able To Do

  • You will be able to read an event's rung on the ladder and act with that rung's verbs.
  • You will be able to run the swollen-pack conversion calmly, completely, and on record.
  • You will be able to respond to a venting cell — people first, containment only if trivially safe, plume never breathed.
  • You will be able to manage fire honestly — containment, cooling water on lithium-ion, evacuation thresholds — and run the aftermath's reignition watch and record.
  • You will be able to retire every pack by the disposal law — taped, bagged, streamed — with damaged packs on the hazmat route and nothing damaged in the post.

Required Tools

  • The fireproof container and its inert reserve — staged within arm's reach, always
  • Long tongs and heat-resistant gloves — the venting cell's only acceptable handles
  • A water source with volume — for cooling surroundings and breaking propagation on lithium-ion
  • Kapton tape, bags, and the disposal log — the quiet week's emergency equipment
  • The posted plan — evacuation route, emergency numbers, and the ladder's verbs where eyes land

When NOT to Attempt This

Do not attempt this section if any of the following apply to you:

  • This procedure involves meaningful risk — read all safety notes before starting.
  • You do not have a safe, well-ventilated workspace ready.
  • You are unfamiliar with the tools or materials described.

Section Overview

The volume ends with the section everything else exists to keep rare — what the bench does when lithium stops being routine (battery-systems-overview-and-lithium-safety-foundations). The ladder reads first. Swollen is stable trouble and gets calm verbs; a cell in cell venting is active trouble and gets people-first verbs; flame is the failure finishing and gets honesty (smartphone-battery-replacement). The swollen protocol is the drilled one. No pressing, containment at sight, the photograph, the conversion — run calmly because the dome is stable exactly until it is handled wrong (battery-replacement-across-device-families). The venting response is minutes that matter. People move first, the plume goes unbreathed, ventilation opens, and the cell reaches containment only if tongs and seconds can do it. The thermal event gets the truth. Containment holds it, extinguishers knock flame without stopping runaway, water in volume cools neighbors and breaks propagation on lithium-ion — never on lithium-metal — and anything beyond one small contained cell belongs to evacuation and emergency services (controller-connectivity-and-battery-repair). And the quiet weeks run the disposal law. Every pack taped, bagged, and out through the recycling stream — never the trash — with damaged packs on the hazmat route. The ladder, the protocols, the truth about fire, the aftermath, the law — the last bench entire.

Why This Matters

Every chapter of this volume staged equipment and rules for an afternoon it hoped would never come, and this section is that afternoon rehearsed (battery-systems-overview-and-lithium-safety-foundations). This matters because the rungs have different verbs and adrenaline confuses them: a swollen pack treated as a fire gets thrown and jostled into becoming one, and a venting cell treated as a swollen pack gets handled at face level — the ladder exists so the body knows which afternoon it is having (smartphone-battery-replacement). This matters because the water folklore cuts both ways: the bench that believes 'never water on lithium' watches propagation take a shelf it could have cooled, and the one that aims water at a lithium-metal primary makes it worse — the honest rule has two halves and both save property (battery-replacement-across-device-families). It matters because finished is a trap: cells reignite hours after they seem done, and the reignition watch is the difference between an incident and a building fire that started at closing time. It matters because the fumes are not smoke: a venting cell's plume is electrolyte vapor and worse — flammable, toxic, and never worth one diagnostic sniff (controller-connectivity-and-battery-repair). And it matters because disposal is the emergency in slow motion: the pack binned into ordinary trash starts its fire at the truck or the facility, wearing the shop's name — the recycling stream is the law's last clause, run every quiet week. Know the rung, move the people, use water honestly, watch the aftermath, tape everything out the door — and the section the volume hoped you would never need becomes the one you were readiest for.

Required Prerequisites

  • Kapton tape and heavy bags at every bench — to make the taping law effortless the hour any pack retires (battery-replacement-across-device-families)
  • Sand or vermiculite reserve beside the container — to give a venting cell somewhere inert to finish (battery-systems-overview-and-lithium-safety-foundations)
  • A posted plan — evacuation route, emergency numbers, the ladder's verbs — to let the worst afternoon read instructions instead of remembering them
  • A disposal log and labeled hazmat-route containment for damaged packs — to run the quiet half of the law on record (controller-connectivity-and-battery-repair)
  • The shop's own battery station, walked as hardware — to find every piece of emergency equipment by touch before an afternoon demands it (battery-systems-overview-and-lithium-safety-foundations)
  • A retired, taped, healthy pack kept as a drill prop — to rehearse the swollen conversion's motions without live risk (smartphone-battery-replacement)
  • Long tongs and the heat gloves, handled until familiar — to make the tongs-and-seconds decision with practiced hands (battery-replacement-across-device-families)
  • Scenario cards for the tabletop drill — venting, flame, aftermath — to rehearse verbs and thresholds at zero stakes (controller-connectivity-and-battery-repair)
  • The local recycling and hazmat drop-off list, verified quarterly — to keep the stream's addresses as current as the law

Real-World Applications

The last bench proves itself in afternoons nobody schedules. A technician whose intake inspection finds a customer tablet's pack subtly domed runs the drilled protocol without drama — nothing pressed, the pack photographed in place, the device carried level to the fireproof container, the owner called with the conversion explained — a stable problem kept stable by calm verbs (smartphone-battery-replacement). A bench whose pull goes wrong — a pouch nicked, the hiss and sweet solvent smell starting — moves people first, holds its breath away from the plume, takes the cell to containment in one tongs-and-seconds motion, opens the shop's air, and starts the reignition watch — the afternoon the equipment was staged for, survived by preparation (battery-systems-overview-and-lithium-safety-foundations). A counter receiving a shoebox of dead packs a customer meant to bin redirects them through the law: terminals taped on the spot, bagged, into the stream's box, with the two swollen ones routed to the hazmat containment and the customer shown why the trash was never an option (controller-connectivity-and-battery-repair). And a shop hearing that a neighboring unit's e-bike pack went up overnight audits its own station the next morning — water access, container clearance, the posted plan, the series-string refusals — because the nearest miss is the cheapest drill (battery-replacement-across-device-families). The failures this prevents: a dome jostled into venting by hurried hands, a lungful of electrolyte plume taken for a diagnostic sniff, a shelf lost to propagation that water would have broken, and a bin fire at the recycling truck wearing the shop's name.

Common Challenges

  • Adrenaline flattens the ladder. Every rung feels like fire once the heart rate rises — the difficulty is training the verbs until the body sorts stable from active from finishing without deliberation (battery-systems-overview-and-lithium-safety-foundations).
  • The heroic instinct points backward. The hands want to grab, smother, and save the workpiece — the difficulty is that every correct verb moves away first: people, then air, then — only if trivial — the cell (smartphone-battery-replacement).
  • The quiet law bores. Taping terminals on dead packs feels like filing — the difficulty is honoring the disposal law on week two hundred the way it was honored on week one, because the bin fire does not care how routine the shop had gotten (battery-replacement-across-device-families).

Safety Notes

Risk Level: High. This section handles lithium at its worst — and its first rule is that most of the handling is not handling at all.

When NOT to Attempt This Repair

The emergency bench has boundaries that hold even harder than the others, because crossing them costs more than boards:

  • Never fight anything beyond one small cell already in containment — a multi-cell pack in runaway, a series string, a device fire spreading past its shell: evacuate and call emergency services, immediately and without inventory-saving detours.
  • Never re-enter for property — not the customer's device, not the shop's tools, not the day's takings; the reignition watch exists because the fire is not done when it looks done.
  • Never handle a venting cell at face level, barehanded, or for more than seconds — tongs and one short motion to containment, or the cell stays where it is and the people leave.
  • Never breathe the plume to assess it — there is no diagnostic sniff; the smell that reaches you at distance has already said everything it needed to.
  • Never put water on lithium-metal primary cells — the coin and camera batteries whose chemistry answers water with worse; water's cooling role belongs to lithium-ion packs and their surroundings, and when the chemistry is unknown, cool around rather than on.
  • Never bin lithium, and never ship damaged packs by ordinary post — the trash fire happens at the truck or the facility, the postal fire happens in a van full of parcels, and both wear the shop's name; the recycling stream and the hazmat route exist for exactly these.

These boundaries are the volume's most absolute, because this is the one bench where the worst case is not a dead board. The refusal, the evacuation, and the phone call are the professional moves.

Professional Tips Before Starting

  • Post the plan where eyes land under stress. Evacuation route, emergency numbers, the ladder's verbs, the water rule's two halves — the worst afternoon reads instructions; it does not remember them (battery-systems-overview-and-lithium-safety-foundations).
  • Drill the tongs motion quarterly. From bench to container, one motion, with the prop pack — practiced hands make the tongs-and-seconds judgment honestly (smartphone-battery-replacement).
  • Verify the stream's addresses quarterly. Drop-offs close, rules change, hazmat routes move — the disposal law is only as good as its current addresses (controller-connectivity-and-battery-repair).

The Last Bench — The Ladder, The Protocols, The Truth About Fire, The Law

Recap and Frame

Every chapter of this volume staged something this section finally uses (battery-systems-overview-and-lithium-safety-foundations). The foundations built the why. The separator's truce, runaway's self-oxidizing arc, the containment doctrine — the chemistry that makes every verb below make sense. The phone bench built the first protocol. Swelling conversion at sight, drilled as routine so it stays calm under pressure (smartphone-battery-replacement). The replacement bench built the quiet law. Taped terminals within the hour, the gates before every job — the habits that keep most afternoons ordinary (battery-replacement-across-device-families). The accessory bench proved the law scales. Small packs, whole rules — the fireproof container indifferent to size (controller-connectivity-and-battery-repair). What is new is the worst case, rehearsed. The ladder's rungs with their verbs, the truth about what works on fire, the aftermath nobody teaches, and the disposal law that runs the quiet weeks. And this section closes the volume: eight chapters of repair discipline, ending at the bench that keeps every other one safe. Hold the frame — everything staged, nothing improvised — and the worst afternoon becomes procedure.

The Ladder — Three Rungs, Three Sets of Verbs

Battery trouble arrives in three grades, and the whole section hangs on telling them apart (battery-systems-overview-and-lithium-safety-foundations). Swollen is stable trouble. The dome is gas behind a membrane that has not failed — trouble announced, not trouble underway — and its verbs are calm: nothing pressed, nothing hurried, the device carried level, containment at sight, the record and the owner's call (smartphone-battery-replacement). Venting is active trouble. The hiss, the sweet solvent smell, smoke without flame — the cell is leaking its electrolyte as vapor and may be minutes from ignition — and the verbs turn outward: people first, plume unbreathed, ventilation open, and the cell moved only if tongs and seconds can do it (battery-replacement-across-device-families). Flame is the failure finishing. Runaway underway makes its own oxygen and its own schedule — the verbs become containment for what is already held, cooling water for everything around it, and evacuation with emergency services for anything more (controller-connectivity-and-battery-repair). The rungs escalate one way. Swollen can become venting when handled wrong, venting becomes flame on its own clock — the ladder is climbed by mistakes and descended never, which is why each rung's verbs assume the next rung is coming. Stable, active, finishing — the ladder entire. Read the rung before moving, because the verbs that save one rung feed the next.

The Protocols — Swollen Calm, Venting Fast

The two survivable rungs each get a protocol, and they could not be more different in tempo (smartphone-battery-replacement). The swollen protocol is deliberately slow. The dome found at intake or mid-job stops the work where it stands; nothing presses, nothing pries; the photograph happens in place; the device travels level and unsqueezed to the fireproof container; the owner hears the conversion with the photo attached; and the pack waits in containment — never a drawer — for the hazmat route (battery-replacement-across-device-families). Storage of the stable-but-swollen is part of the protocol. Containment, labeled, away from the bench's heat and traffic, logged for the next disposal run — a swollen pack is a converted ticket, not an ornament. The venting protocol is deliberately fast — outward. At the first hiss or sweet smell: people move away and upwind, the room's air opens, and nobody's face comes near the source (battery-systems-overview-and-lithium-safety-foundations). The one inward motion is conditional. If — and only if — long tongs and a few seconds can carry the cell to the container, one person does it in one motion and retreats; if the geometry, the heat, or the smoke says otherwise, the cell stays and the people leave — the container was cheap and the lungs are not (controller-connectivity-and-battery-repair). Then the watch begins. A vented cell that never flamed still gets the aftermath's full treatment — reignition watch, ventilation, untouched until cold and beyond. Slow for the stable, fast and outward for the active, one conditional motion inward — the protocols entire. Tempo is the protocol: calm keeps the swollen stable, and speed keeps the venting survivable.

The Truth About Fire — What Works, What Pretends

Lithium fire attracts folklore, and the bench needs the physics instead (battery-systems-overview-and-lithium-safety-foundations). Containment works by admitting what it cannot do. The fireproof container does not extinguish anything — it holds a self-oxidizing failure while it finishes, somewhere fireproof, which is the whole plan and a good one. Extinguishers do less than they promise. A standard extinguisher can knock down the flames of burning plastics and electrolyte around the cell — worth doing — but it does not stop the runaway underneath, and a cell that looks extinguished is a cell mid-runaway with less drama (smartphone-battery-replacement). Water's real job is the neighbors. Water in volume cools the cells and materials around the failure, quenches what the runaway is trying to ignite, and breaks propagation through a pack or a shelf — on lithium-ion this is not folklore-forbidden but the professional move, which is why fire services flood these fires (battery-replacement-across-device-families). The exception is lithium-metal. Primary lithium cells — coins, camera batteries — carry metallic lithium that reacts with water; their fires get dry sand or Class D dry-powder agents and distance, and the unknown-chemistry rule is cool around, not on (controller-connectivity-and-battery-repair). And the threshold is written in advance. One small cell already in containment: manageable. Anything more — a multi-cell pack, a series string, spread past the shell — evacuation and emergency services, with the shop's plan already posted because the decision was made on a calm day. Containment holds, extinguishers pretend, water cools the right things, lithium-metal refuses water, and the threshold was decided in advance — the truth entire. The bench's job in a real fire is to have already done its job — staging, thresholds, and the call.

The Aftermath and the Law — The Watch, The Record, The Stream

What happens after the drama decides whether it repeats, and the quiet law runs whether or not drama ever came (battery-replacement-across-device-families). The reignition watch stands for hours. Cells relight after they seem finished — heat soaking inward reaches material that had not yet failed — so the site stays watched, the debris stays untouched, and 'done' is declared by time and cold, not by appearance (battery-systems-overview-and-lithium-safety-foundations). The fumes outlast the flame. Ventilation stays open through the watch; residue and debris are handled gloved and never bare; and anything that smells wrong stays quarantined in containment (smartphone-battery-replacement). The record turns incident into process. What failed, at which rung, which verbs ran, what the staging got right and wrong — written while fresh, because the incident that improves the station paid for itself and the one that goes unrecorded gets to happen twice. And the disposal law runs every quiet week. Every retired pack taped the hour it retires, bagged, logged, and out through the recycling stream — retail drop-offs and e-waste programs for the healthy dead, the hazmat route in containment for the swollen and damaged that drop-offs refuse — and nothing damaged ever in ordinary post, because the parcel fire is the bin fire with tracking (controller-connectivity-and-battery-repair). The stream is the law's last clause. The fire follows the pack until the stream takes it — which is why the tape goes on at the bench, not at the door. Watch, air, record, tape, stream — the aftermath and the law entire. The volume ends where its rules began: the pack leaves safely, or it has not left.

Common Mistakes

  • Treating the swollen rung as the fire rung. The domed pack snatched, jostled, and thrown — stable trouble stays stable under calm verbs; the hurry is what climbs the ladder (smartphone-battery-replacement).
  • The diagnostic sniff. Leaning in to identify the smell — the plume that reached you at distance already answered; there is no second question worth a lungful (battery-systems-overview-and-lithium-safety-foundations).
  • Believing the extinguisher. The knocked-down flame declared over — runaway continues under the powder, and the reignition watch starts regardless (battery-replacement-across-device-families).
  • Withholding water from a lithium-ion propagation. The shelf lost to folklore — water's job is the neighbors, and on lithium-ion it does that job well; the refusal belongs to lithium-metal alone (controller-connectivity-and-battery-repair).
  • Binning the boring dead. The healthy-looking retired pack in the trash because taping felt like filing — the bin fire happens at the truck, days later, wearing the shop's name.

Troubleshooting Guidance

The last bench troubleshoots afternoons, not devices: rung, verbs, threshold, watch. If a pack is domed but quiet: the swollen protocol — calm, level, photographed, contained, converted — and the hazmat route when the disposal run goes (smartphone-battery-replacement). If there is hiss, sweet smell, or smoke without flame: venting — people and air first, tongs-and-seconds or nothing, and the watch afterward even if flame never came (battery-systems-overview-and-lithium-safety-foundations). If there is flame in containment, small and single: let containment do its job, cool the surroundings, keep people back, start the watch (battery-replacement-across-device-families). If there is flame beyond that — multi-cell, series string, spreading: evacuation and emergency services, immediately, with re-entry refused until cleared. If the event seems over: it is not — hours of watch, untouched debris, open air, and the record written while fresh (controller-connectivity-and-battery-repair). If the week was quiet: the law still ran — tape, bag, log, stream — and the station audit found the water, the tongs, and the plan where they belong. The throughline: read the rung, run its verbs, respect the threshold, stand the watch — and let the quiet law make the loud afternoons rare.

Verification & Testing Methods

Confirm the last bench before it is ever needed:

  • [ ] I can read the ladder's rung from the evidence — dome, hiss and smell, flame — and name each rung's verbs without deliberation.
  • [ ] I run the swollen protocol calm and complete — nothing pressed, photographed in place, contained, converted, stored for the hazmat route.
  • [ ] I respond to cell venting outward — people first, plume never breathed, ventilation open, tongs-and-seconds or the cell stays.
  • [ ] I manage a thermal event honestly — containment holding, water cooling the surroundings on lithium-ion and never on lithium-metal, evacuation and emergency services at the written threshold — and I stand the reignition watch after.
  • [ ] I run the disposal law weekly — every pack taped and bagged into the recycling stream, damaged packs on the hazmat route, nothing damaged in the post, all of it logged.

Then try the practice exercises below — drills, props, and desk work only; no exercise here touches live failure, and scenarios differ from the quiz.

Practice Exercises

  1. Walk the station blind (5 minutes, the bench itself). Stand at the bench and reach for each piece of emergency equipment without searching — container, inert reserve, tongs, gloves, water access, the posted plan — then walk the evacuation route once, and fix anything that took a search instead of a reach, because the afternoon this rehearses will not wait for inventory (battery-systems-overview-and-lithium-safety-foundations).
  2. Run the swollen conversion on the prop (5 minutes, drill prop pack, camera, the container). Treat the prop as a dome found mid-job: stop, photograph in place, carry level to containment in one calm motion, write the owner-call script's three sentences — what was found, why the job converts, what happens next — and log the prop into the hazmat-route containment as if it were real (smartphone-battery-replacement).
  3. Table the venting and fire scenarios (5 minutes, scenario cards, the posted plan). Deal three cards — venting at the bench, small flame in containment, flame beyond the threshold — and for each, say the verbs aloud in order: who moves, where the air opens, whether tongs-and-seconds applies, where water goes and where it must not, when the call happens — and for each card, finish the afternoon: when the reignition watch starts, how it ends — time and cold, never appearance — and the incident record's first three prompts said aloud — then check every answer against the posted plan and correct the plan or the answers until they agree (battery-replacement-across-device-families).
  4. Run the disposal audit (3 minutes, the real retired-pack box). Tape and bag any untaped retired packs on the spot, verify the stream's drop-off list and the hazmat route's address are current, confirm nothing damaged is staged for ordinary post, and log the run — the quiet law, actually run (controller-connectivity-and-battery-repair).

These core steps — the blind station walk, the prop conversion, the tabletop verbs, and the disposal audit — are tested in the Chapter Quiz at the end of this chapter, where a score of 80% is required to continue.

Key Takeaways

  • The ladder has three rungs and three tempos — swollen is stable and gets calm, venting is active and gets speed outward, flame is the failure finishing and gets honesty — and the ladder is climbed by mistakes, descended never (battery-systems-overview-and-lithium-safety-foundations).
  • The venting response runs outward: people first, the plume never breathed, ventilation open, and the one inward motion — cell venting to containment — happens only if tongs and seconds can do it (smartphone-battery-replacement).
  • The truth about fire: containment holds a thermal event without extinguishing it, extinguishers knock down flame without stopping runaway, and water in volume cools neighbors and breaks propagation on lithium-ion — never on lithium-metal — with evacuation and emergency services owning everything past one small contained cell (battery-replacement-across-device-families).
  • The aftermath is part of the event — the reignition watch stands for hours, debris stays untouched, air stays open, and the record turns the incident into a process fix.
  • The disposal law runs the quiet weeks: every pack taped and bagged into the recycling stream, damaged packs on the hazmat route in containment, nothing damaged ever in ordinary post — because the fire follows the pack until the stream takes it (controller-connectivity-and-battery-repair).

Skills Learned

  • You can now read an event's rung on the ladder and act with that rung's verbs.
  • You can now run the swollen-pack conversion calmly, completely, and on record.
  • You can now respond to a venting cell — people first, containment only if trivially safe, plume never breathed.
  • You can now manage fire honestly — containment, cooling water on lithium-ion, evacuation thresholds — and run the aftermath's reignition watch and record.
  • You can now retire every pack by the disposal law — taped, bagged, streamed — with damaged packs on the hazmat route and nothing damaged in the post.

Glossary Additions

  • cell venting — the active-failure stage where a lithium cell releases its electrolyte as vapor: the hiss of escaping gas, the characteristic sweet solvent smell, and smoke without flame, sometimes only minutes ahead of ignition. Venting flips the bench's verbs outward — people move first and upwind, the plume is never breathed even briefly because it is flammable electrolyte vapor and decomposition products together, ventilation opens immediately, and the cell travels to containment only under the tongs-and-seconds rule: one person, one short practiced motion, or the cell stays where it is and the people leave. A cell that vents without ever flaming still earns the full aftermath — the reignition watch, open air, and untouched-until-cold handling — because venting is runaway's overture, not its cancellation.
  • thermal event — a lithium failure that has reached heat and flame: runaway underway, making its own oxygen on its own schedule. The bench's honest toolkit is small and decided in advance — the fireproof container holds a burning cell without extinguishing it, which is the plan working; a standard extinguisher can knock down surrounding flame but does not stop the runaway beneath it; water in volume does the one job it can do, cooling neighbors and breaking propagation on lithium-ion chemistry — never on lithium-metal primaries, which react with water — and everything past one small cell already in containment belongs to evacuation and emergency services. The event ends by time and cold, not appearance: the reignition watch stands for hours, because finished cells relight.
  • recycling stream — the legitimate exit path every retired battery must take: terminals taped the hour the pack retires, bagged, logged, and delivered to retail take-back programs, e-waste collection, or household hazardous-waste facilities — never the trash, because binned lithium starts its fire at the truck or the sorting facility, days later and wearing the shop's name. The stream has a second lane for the packs that need it: swollen, punctured, or heat-damaged cells travel in containment by the hazmat route, because ordinary drop-offs refuse damaged lithium — and nothing damaged ever ships by ordinary post, where the parcel fire is the bin fire with a tracking number. The stream is the lithium law's final clause: the fire follows the pack until the stream takes it.
