This pure acid has a slight yellow-green tint, and is soluble in water. However, the diluted version may develop a brownish tint, from corrosion at the anode. When we charge a lead-acid battery, lead oxide forms on the positive plate, causing the electrolyte to become denser.
LEAD-ACID BATTERIES Lead-acid batteries use highly corrosive diluted sulfuric acid as their electrolyte. This pure acid has a slight yellow-green tint, and is soluble in water. However, the diluted version may develop a brownish tint, from corrosion at the anode.
Typically, a light green dot indicates a fully charged battery. The electrolyte solution is close to 1.265, heavier than water (1.0). Maintenance-free batteries have relief valves that prevent pressure buildup. Manufacturers refer to them as VRLA or valve-regulated lead-acid batteries.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.
Manufacturers refer to them as VRLA or valve-regulated lead-acid batteries. A dark green/black indicator on a maintenance-free battery typically indicates that the battery needs a charge. The electrolyte has undergone a chemical reaction and is now closer to water. Charging a battery with a dark indicator restores the solution's specific gravity.
