Eli5: Why do batteries have the potential to explode?
It''s actually pretty hard to get lead/acid batteries to explode. However, if there is a build-up of hydrogen gas inside the battery, and if the battery is damaged and enough heat is generated, or a spark, the battery can explode. The acid in the batteries (sulfuric acid) is not itself flammable, but it is acid so you don''t want to get that on
