What occurs if the electrolyte specific gravity exceeds 1.23

Select your answer for: What occurs if the electrolyte specific gravity exceeds 1.23
Show answer

Answer: D. All above

Explanation

High electrolyte specific gravity indicates an excessive concentration of sulfuric acid in the battery solution. This high concentration accelerates chemical attacks on the internal lead grids causing severe plate corrosion. Consequently, the active materials degrade rapidly, resulting in irreversible capacity loss and shortened operational life. Electrolyte specific gravity measures the density of the battery acid solution compared to pure water reference levels. A fully charged lead-acid battery typically exhibits a specific gravity ranging from approximately 1.265 to 1.280. Grid structures inside lead-acid batteries provide mechanical support and electrical conductivity for the active material pastes.

Loss of capacity occurs independently but is directly accelerated by the destructive effects of high acid concentration. Loss of life refers to the premature failure of the battery caused by the cumulative damage from high acidity. Corrosion of the grids is a primary physical mechanism that simultaneously triggers both capacity loss and lifespan reduction.
