Batteries can explode through misuse or malfunction. By attempting to overcharge a rechargeable battery or charging it at an excessive rate, gases can build up in the battery and potentially cause a rupture. A short circuit can also lead to an explosion. A battery placed in a fire can also lead to an explosion as steam builds up inside the battery.

Recharging the battery converts all the lead sulfate crystals on the surface back into lead metal crystals. This process can be repeated many times. However, if a battery is for any reason not fully recharged, the deeply underlying lead conductive paths themselves start to become sulfated. Lead sulfate is not a good conductor of electricity.
