Swollen Laptop Battery: What to Do Right Now, and How to Dispose of It Safely
By National Recycling Co. · Updated 18 October 2026 · 6 min read
Your trackpad has started to lift, the laptop rocks on the table, or the lid won’t close flat. That’s almost always a swollen lithium-ion battery. It isn’t an emergency yet, but it can become one. Here’s what to do in the next ten minutes, and what to do with the laptop afterwards.
Signs your laptop battery is swollen
- Trackpad raised, clicking on its own or hard to press
- Bottom case bulging, or the laptop wobbles on a flat table
- Gap opening between the keyboard deck and the base
- Lid no longer closes flat, or the screen is being pushed from behind
- Removable battery that no longer sits flat in its slot
What to do right now
- Stop using it and unplug the charger. Charging is what pushes a damaged cell further.
- Shut it down. Save what you can quickly and power off. Don’t leave it sleeping.
- Don’t press, puncture or try to flatten it. Don’t close the lid hard to “push it back in”.
- Move it to a safe spot. A tiled floor, a metal tray or a ceramic surface, away from curtains, bedding, paper and sofas. Not in a cupboard and not in the sun.
- Don’t put it in the fridge or in water.
- Back up your data only if you can do it without charging the laptop. Otherwise the drive can be removed later and read safely.
Should I take the battery out myself?
Removable battery (older laptops with a latch underneath): if it slides out easily, take it out and store it separately on a non-flammable surface.
Internal battery (most laptops from the last ten years): it’s screwed or glued inside. Prying a swollen cell out with a screwdriver can puncture it, and a punctured lithium cell can catch fire. Unless you’re experienced, leave it in and hand the whole laptop over.
Why laptop batteries swell
- Age. Most laptop batteries are tired after 3–5 years. An unused laptop’s battery still ages in the cupboard.
- Heat. Using a laptop on a bed or pillow, or leaving it in a hot car, speeds up the chemical breakdown that produces gas inside the cell.
- Always plugged in at 100%. Keeping a battery fully charged for months stresses it.
- Cheap replacement batteries without proper protection circuits.
Replace the battery or let the laptop go?
| Your laptop | Our honest advice |
|---|---|
| Under 5 years old, otherwise fine | Get a genuine replacement battery fitted at a service centre |
| 2012–2016, still useful | A replacement may be worth it if you’ll actually use it; get a quote |
| Older, or already slow / damaged | Not worth a new battery. Recycle it, or donate it |

How to stop it happening to your next laptop
- Use it on a hard surface so the vents can breathe
- Turn on your laptop’s battery-care or “charge limit” setting if it has one (many Lenovo, Asus, Dell, HP and Apple laptops do)
- Don’t leave it in a hot car or in direct sun on a window sill
- Replace batteries only with genuine or reputable parts
- If you’re storing a laptop for months, leave it around half charged, not full or empty
