Question 436Electricity & Electronics - QMED

The correct answer is D) a dangerously explosive gas being liberated. During the charging of lead-acid storage batteries, the electrolysis of the sulfuric acid solution results in the production of hydrogen gas. This hydrogen gas is highly flammable and explosive, posing a significant safety hazard. Proper ventilation and precautions are essential when charging lead-acid batteries to prevent the accumulation of this explosive gas. The other answer choices are incorrect: A) Lead poisoning is not a direct result of charging lead-acid batteries. B) Local action, which is the self-discharge of a battery, is not a consequence of the charging process. C) Acid burns can occur, but the direct result of charging is the production of explosive hydrogen gas.
