Is it dangerous to store swollen or damaged lithium batteries while waiting for pickup, and how should I handle that?
Short answer: Yes — swollen or physically damaged lithium batteries carry a real risk of thermal runaway, which can cause fire, so they should be stored somewhere non-flammable, away from other combustible materials, ideally outdoors or in a fire-rated container, and pickup should be arranged as soon as reasonably possible rather than left indefinitely.

A swollen lithium battery indicates internal gas buildup from a chemical breakdown inside the cell, which signals instability — this kind of damage significantly increases the risk of the battery entering thermal runaway, a self-sustaining, hard-to-stop reaction that can result in fire.
How to store it safely while waiting
Keep a damaged or swollen battery away from anything flammable, ideally in a fire-resistant container or bag designed for lithium battery storage, in a well-ventilated area away from where people spend significant time — outdoors or in a detached space is generally safer than inside a home.
Don’t let it sit indefinitely
The longer a damaged battery is stored, the longer the risk window remains open. Arrange collection as soon as you reasonably can rather than treating it as a low-priority task, and be upfront with the buyer or transporter about the damage so they can plan appropriate handling.
