They can also explode when subjected to a high or persistent electrical current.

What happens if a battery gets hot?

Heat is a major battery killer because it makes the batteries work harder. … If batteries are exposed to excessive temperature, they will stop working, bulge, bubble, create sparks and flames, damage your device, or blowup.
