A lead acid accumulatory (storage battery) is connected to a battery charge for over night charging. Which of the following observations will indicate that the battery was partly charged during the next morning

View answer and explanation

Correct option: B

The density of acid has increased

Option B is correct because during the charging process of a lead-acid battery, sulfuric acid is regenerated, increasing the density of the electrolyte.
