Vented Lead Acid Batteries
What is the electrolyte solution in a lead-acid battery?
The electrolyte solution in a lead-acid battery consists of approximately 35% sulfuric acid and 65% water. The acid concentration is usually between 4.2-5 mol/L, and the solution has a density of 1.25-1.28 kg/L. The electrolyte solution plays a vital role in the battery’s operation.
What is the difference between lead acid and electrolyte?
Electrolyte also comes in a polymer, as used in the solid-state battery, solid ceramic and molten salts, as in the sodium-sulfur battery. Lead acid uses sulfuric acid. When charging, the acid becomes denser as lead oxide (PbO 2) forms on the positive plate, and then turns to almost water when fully discharged.

What type of electrolyte is used in a battery?
The electrolyte of a battery consists of soluble salts, acids or other bases in liquid, gelled and dry formats. Electrolyte also comes in a polymer, as used in the solid-state battery, solid ceramic and molten salts, as in the sodium-sulfur battery. Lead acid uses sulfuric acid.
How much acid should be in a battery?
In a functional lead-acid battery, the ratio of acid to water should remain close to 35:65. You can use a hydrometer to analyze the precise ratio.
