Laptop and phone batteries are small lithium-ion or lithium-polymer cells that are usually recycled either alone or inside the device. They are the most common lithium battery in offices and electronics recycling streams, and a swollen cell is a warning sign, not just a nuisance. This page covers how to identify them, prepare them and ship them correctly.
How do you identify laptop and phone batteries?
Most laptop batteries are packs of cylindrical 18650-style cells or flat pouch cells, labeled with voltage, capacity and watt-hours. Phone and tablet batteries are almost always single pouch cells, either removable in older models or glued inside the device. The watt-hour rating is printed on the label or on the device specifications; a typical laptop battery is below the 100 watt-hour threshold that triggers stricter airline and shipping limits.
Chemistry is usually lithium cobalt oxide (LCO) or NMC, often packaged as lithium-polymer when the electrolyte is gelled in a pouch. Cobalt-rich cells like LCO carry more recoverable value per pound than LFP. Tablets, e-readers, smartwatches, wireless earbuds and power banks use similar cells in smaller formats. If the battery is built into a device, treat the whole device as the shipping unit unless a trained person can safely remove it.
- Check for the watt-hour mark and any recall number on the label
- Look for swelling, gaps in the case or a lifted keyboard or screen
- Note whether the battery is removable, internal or glued in
What are the hazards of laptop and phone batteries?
Their main hazard is internal short circuit leading to thermal runaway. Aging, impact, bending, punctures, heat and overcharge can all damage the separator inside a cell. Swelling is caused by gas generation and is a sign the cell is failing. A swollen laptop battery can press against the case and trackpad, and puncturing it can cause fire. Never try to flatten, cut or pry a swollen battery.
In bulk, small batteries create real risk. Boxes of mixed devices and loose cells are common in offices and IT closets, and metal contact between terminals can create heat. A disciplined collection process matters: designate a lidded, non-combustible container with a non-conductive liner, keep it away from paper and cardboard, and remove any swollen unit immediately to separate storage. If a device becomes hot, smokes or hisses, evacuate and call emergency services. Fires can restart hours or days later, so a pack that has stopped smoking is not necessarily safe.
Should you remove the battery from the device before recycling?
Remove it only if the design allows it without tools or force. Many modern devices have glued or soldered batteries, and prying them out can puncture a cell. If you can remove a battery, tape its contacts and bag it separately. If you cannot, ship or hand over the whole device and let the recycler handle battery removal. A device with an internal battery is classified as lithium batteries contained in equipment.
Data is the other consideration. Phones, tablets and laptops hold personal and business data, and battery recyclers are not a substitute for data sanitization. Wipe or physically remove storage before recycling, or use a recycler with documented data destruction. If your organization has an IT asset disposition process, route devices through it first and let the battery step happen downstream. We can coordinate battery-only streams and mixed-device pickups.
- Remove or wipe storage and cloud accounts before handing off devices
- Tape terminals on removed batteries and bag individually
- Do not drill, puncture or crush swollen batteries
How are laptop and phone batteries classified for shipping?
Batteries shipped alone are UN3480 and batteries packed with or contained in equipment are UN3481, both Class 9 under 49 CFR 173.185. Cells and batteries within the small-battery watt-hour limits can ship with reduced requirements, and batteries sent for recycling by motor vehicle have their own provision, 49 CFR 173.185(d), which relaxes testing and packaging rules. A mixed box of unknown batteries should still be treated carefully, with terminals taped and movement prevented.
Ground shipping is the normal route for recycling loads. Air shipping has stricter limits: lithium-ion batteries shipped alone must not exceed 30 percent state of charge, and damaged or defective batteries are not allowed by air. A swollen or recalled laptop battery is a damaged, defective or recalled battery under 49 CFR 173.185(f) and should be separated and packed in non-combustible cushioning inside a rigid box. We will confirm the right description before pickup or shipment.
How do offices and schools manage these batteries as universal waste?
A business can manage spent laptop and phone batteries as universal waste under 40 CFR Part 273, with the EPA’s May 2023 memo clarifying that most lithium battery waste can use that pathway. In practice, set up a labeled collection container for batteries, keep it closed, and send it for recycling within one year. Schools and municipalities often collect these batteries from many sources, so a clear intake rule is useful.
Train staff on three points: do not throw batteries in trash or regular recycling, tape terminals on loose batteries, and isolate swollen or damaged units immediately. For retail and e-commerce, returned devices can arrive with unknown condition, so a damaged-battery container is a worthwhile investment. State rules vary, including who can collect and store batteries, so check the state page for your location and ask us about pickup or prepaid shipping.
What is recovered from laptop and phone batteries, and what affects cost?
Consumer electronics batteries are often cobalt-rich, so recycling can recover cobalt, nickel, lithium, copper, aluminum and graphite. Cells are processed into black mass, then refined through hydrometallurgy or pyrometallurgy. Device housings, circuit boards and plastics follow separate electronics recycling streams. Direct recycling of cathode powder remains mostly in research and pilot work.
Whether batteries arrive loose or inside devices is the first cost question. Loose batteries are cheaper to process than whole devices that need dismantling. Mixed chemistries and unknown batteries add sorting cost. Swollen or damaged units require special packaging. Because there is no one price that fits every load, we quote each shipment after we know the quantity, whether devices are included and where the pickup is. Delivery windows, dock access and equipment needs also change the logistics side of the price.

Frequently asked questions
Is it safe to ship a laptop with its battery inside for recycling?
Yes, as UN3481 lithium-ion batteries contained in equipment, if the device is undamaged and packaged to prevent movement and accidental activation. Swollen or damaged devices need special handling.
What should I do with a swollen laptop or phone battery?
Stop using it, do not charge it and do not press on it. Place it in a non-combustible container away from other materials and contact us for damaged battery handling.
Do I need to erase data before recycling devices?
Yes. Battery recycling does not guarantee data destruction. Wipe or remove storage first, or use an IT asset disposition provider that documents data sanitization.
Can I mix phones, laptops and power banks in one box?
Often yes if terminals are protected and the box is secure, but separate damaged items and tell us the contents. Mixed loads can still be quoted.
Are lithium-polymer batteries treated differently from lithium-ion?
Not for shipping. Lithium-polymer cells are lithium-ion cells in a gel-electrolyte pouch and are shipped under the same UN numbers.
