The risk of explosion is labeled on every automotive battery, though few motorists bother to read such warnings, let alone take them seriously. It’s an unfortunate mistake, because batteries often do explode without warning.
What happens when car battery explodes?
Most car battery explosions are caused by thermal runaway, which is when the battery overheats, causing its cells to break open. Usually, one cell starts a chain reaction in which other cells rupture. A swollen car battery is a less serious manifestation of the thermal runaway effect.
