Handling, Storage, and Disposal of Removed Lithium-Ion Batteries

Why end-of-job handling matters

A removed lithium-ion battery is still an energy source and can become a fire or chemical hazard if its terminals are shorted, its pouch is punctured, or it is stored near heat or flammable materials. End-of-job practices focus on three goals: (1) prevent electrical shorts, (2) prevent mechanical damage and contamination, and (3) route the battery into an appropriate storage and disposal channel.

Immediate actions after removal

1) Isolate the terminals (prevent shorts)

As soon as the battery is free of the device, treat the exposed contacts as live. A short across the terminals can rapidly heat the cell and ignite nearby materials.

• Inspect the contact area for torn flex, exposed metal, or loose conductive debris stuck to adhesive.
• Cover terminals with non-conductive tape (Kapton/polyimide or electrical tape). Ensure the tape fully covers the metal pads and wraps slightly onto the battery surface so it cannot peel back easily.
• Do not use metal clips, staples, or conductive bands to hold anything in place.
• If the battery has a connector on a lead, tape the connector housing so the pins cannot contact tools or other batteries.

2) Bag or containerize (prevent puncture + contain contamination)

Use packaging that prevents the battery from contacting conductive objects and reduces the chance of puncture during handling.

• Preferred: a dedicated non-conductive battery bag or a rigid plastic container with a lid.
• Acceptable: a clean polyethylene (PE) bag plus a rigid outer container (double containment).
• Avoid: thin bags alone in a toolbox where sharp tools can puncture the pouch.
• Separate batteries so they cannot touch each other terminal-to-terminal; use dividers or individual bags.

3) Label and segregate

In a professional environment, labeling prevents accidental reuse and supports compliant disposal.

• Mark the package: “Removed Li-ion Battery — For Recycling/Disposal”.
• Add a simple status note: “Normal” vs “Damaged/Swollen” and the date removed.
• Keep removed batteries in a designated area, not on the active repair bench.

Safe storage conditions (short-term holding)

Store removed batteries as if they could fail without warning. The storage area should reduce heat exposure and keep combustibles away.

Storage rules

• Cool, dry location: avoid direct sun, heaters, hot cars, and high-humidity areas.
• Away from combustibles: keep clear of paper stacks, solvents, aerosols, and cleaning chemicals.
• Stable, non-cluttered surface: prevent crushing under other items.
• Use a dedicated container: a lidded plastic bin or purpose-built battery storage box; keep it closed when not adding/removing items.
• Do not store loose with metal parts (screws, brackets, blades) that can pierce or short terminals.

What “cool and dry” means in practice

• Choose a room-temperature area with minimal temperature swings.
• Avoid windowsills, near charging stations, or near equipment exhaust vents.
• If your shop uses flammable liquids, store batteries in a separate cabinet/area from those materials.

Swollen, punctured, or otherwise damaged batteries

Swelling, dents, torn foil, electrolyte odor, hissing, discoloration, or heat generation indicates elevated risk. These batteries should be treated as damaged hazardous waste and handled with extra controls.

Step-by-step: quarantine procedure

1. Stop handling and clear the immediate area of paper, alcohol wipes, adhesives, and other combustibles.
2. Do not compress or bend the pack to “make it fit” into a bag or container.
3. Isolate terminals with non-conductive tape if you can do so without pressing on the swollen area.
4. Place in a quarantine container: a rigid, non-conductive container with a lid, positioned away from traffic. If available, use a container designed for damaged lithium batteries per your facility policy.
5. Keep it separate from normal returns and label clearly: “Damaged/Swollen Li-ion — Quarantine”.
6. Monitor for heat from a safe distance. If it becomes hot, emits smoke, or vents, follow your site emergency response plan and evacuate as required.

Do-not-ship guidance (when applicable)

Shipping rules vary by region and carrier, but a practical rule for technicians is: do not ship swollen, leaking, or physically damaged lithium-ion batteries through standard mail/courier channels. These often require specialized hazardous materials packaging, labeling, and approved carriers.

• Do not include damaged batteries in customer return boxes unless your organization has an approved hazmat shipping program.
• Do not fly with damaged batteries in checked baggage or carry-on unless explicitly permitted by applicable regulations and airline policy (often prohibited).
• Escalate to your hazardous waste or EHS contact for the correct route.

When to seek hazardous waste channels immediately

• Battery is swollen enough to deform covers or has a “pillowed” pouch.
• Any sign of leakage, odor, corrosion, or wetness near the pack.
• Puncture, crease, or torn foil on a pouch cell.
• Battery was involved in a thermal event (hot to touch, venting, smoke).

Disposal workflow (individual and professional environments)

Disposal is not “throw it away.” Lithium-ion batteries should be routed to recycling or hazardous waste programs that can safely process them.

Workflow overview

Step-by-step: local recycling requirements

1. Identify your jurisdiction’s rules (city/county/state/country). Many areas prohibit lithium batteries in household trash.
2. Check accepted types: some drop-offs accept “rechargeable batteries,” others require “lithium-ion only,” and damaged packs may be excluded.
3. Prepare the battery: terminals taped, individually bagged, and placed in a rigid container for transport.
4. Transport safely: keep away from heat in your vehicle; do not leave in a hot car.
5. Hand off to an approved collection point (retailer collection bin, municipal hazardous waste facility, or certified recycler).

E-waste drop-off options

• Municipal e-waste events or permanent household hazardous waste facilities.
• Retail take-back programs that accept rechargeable batteries (verify acceptance of lithium-ion packs and condition limits).
• Certified electronics recyclers for businesses with recurring volume.

Documentation for professional environments

Shops and IT departments often need traceability for safety audits, customer records, and environmental compliance.

• Log entry per battery: device ID/serial (if applicable), battery model, removal date, condition (normal/damaged), and technician initials.
• Chain-of-custody: record where it was stored, when it was transferred, and to whom (recycler/vendor).
• Weight/count tracking: number of batteries in each batch and approximate weight for recycler manifests.
• Incident notes: if swelling/damage was observed, note quarantine actions taken and any escalation to EHS.

Example internal log fields (minimal): Date | Device ID | Battery type | Condition | Storage bin ID | Disposition (Recycler/HazWaste) | Ticket #

Workspace clearing checklist (before returning the device to service)

Use this checklist to ensure the bench and device area are free of hazards that could puncture a battery, short electronics, or contaminate adhesives.

• Removed battery handled: terminals taped; placed in a non-conductive bag/container; labeled; moved to designated storage area.
• No conductive debris: loose screws, metal shards, foil fragments, or clipped leads removed from the bench mat and device cavity.
• Adhesive cleanup: old adhesive strips, pull-tab remnants, and sticky residue disposed of properly; no loose adhesive that can trap debris.
• Puncture hazards removed: blades, picks, broken spudgers, cracked plastic, or sharp bracket edges not left in the work zone.
• Chemical materials secured: solvents/cleaners capped and stored; used wipes placed in appropriate waste container.
• Tool accountability: count/verify tools and bits; nothing left inside the device.
• Bench reset: non-conductive waste emptied; quarantine container closed; storage bin area tidy and separated from combustibles.
