Technical FAQs 4

What does sulphuric acid do in a battery?

It facilitates the exchange of ions between the battery’s anode and cathode, allowing for energy storage and discharge. Sulfuric acid (or sulphuric acid) is the type of acid found in lead-acid batteries, a type of rechargeable battery commonly found in vehicles, emergency lighting systems, and backup power supplies.

What is battery acid (diluted sulfuric acid)?

Key Properties: Battery acid (diluted sulfuric acid) has powered lead-acid systems for over a century, demonstrating consistent performance in automotive, industrial, and grid applications under various environmental conditions.

What is battery acid?

Its composition and Roles Battery acid is a dilute solution of sulfuric acid (H₂SO₄) used in lead-acid batteries. Comprising 29%-32% sulfuric acid, it facilitates the flow of electrical current between the battery’s plates. This highly corrosive electrolyte is essential for generating electrical energy in vehicles and other applications.

Is sulfuric acid a good battery?

Compared to modern lithium-ion batteries, sulfuric acid systems offer inferior energy density (~30–40 Wh/kg), making them unsuitable for weight- or volume-constrained applications like mobile electronics or aviation. Over time, issues like acid stratification, sulfation of plates, and water loss degrade battery performance.
