What is the explosive gas produced by an automotive battery?

• A. Oxygen
• B. Nitrogen
• C. Hydrogen
• D. Carbon dioxide

Answer: (C)

The explosive gas produced by an automotive battery is hydrogen. This gas is generated during the charging process of the battery where lead-acid cells are involved. When an automotive battery is charged, particularly if it is overcharged, electrolysis occurs—breaking down water into hydrogen and oxygen. The hydrogen gas can accumulate and, if ignited, may lead to an explosion, making it highly hazardous. This understanding highlights the need for proper ventilation when working with or charging batteries to prevent the buildup of hydrogen gas, which is flammable. The relevance of hydrogen in this context illustrates the importance of safety precautions in automotive maintenance and operation.
