Explore our full range of high-purity \u003ca href=\"\/collections\/acids\"\u003eacids\u003c\/a\u003e to find the correct concentration for your operations. With a chemical identity defined by CAS Number 7664-93-9, molecular formula H2O4S, and a molecular weight of 98.08, this product represents a stable, aqueous dilution of sulfuric acid. As a critical component in lead-acid battery technology, this specific 37% concentration provides optimal electrolyte performance, facilitating the necessary reversible electrochemical reactions that store and release electrical energy in backup power systems and industrial machinery.\u003c\/p\u003e\n\u003cp\u003eAlliance Chemical supplies this colorless, odorless oily liquid to meet the rigorous specifications required by industrial operators, manufacturers, and fleet maintenance departments. This concentration exhibits a density of 1.841 (EPA, 1998) — which is denser than water — and is completely miscible in water, releasing significant heat upon dilution. Due to its corrosive nature, it must be handled with extreme precision and under strict safety protocols. This material serves as a foundational acid in chemical manufacturing, metals processing, and industrial battery servicing across North America.\u003c\/p\u003e\n\u003ch3\u003eWhy This Grade\u003c\/h3\u003e\n\u003cp\u003eChoosing a precise 37% concentration of sulfuric acid is critical for electrochemistry and industrial \u003ca href=\"\/pages\/industries\/battery-manufacturing\"\u003ebattery manufacturing\u003c\/a\u003e. In lead-acid batteries, the electrolyte concentration must remain within a narrow tolerance band to ensure proper ion mobility and prevent degradation of the lead plates. If the concentration is too high, it accelerates the sulfation process and corrodes the internal grids, permanently reducing the battery’s capacity and overall lifespan.\u003c\/p\u003e\n\u003cp\u003eConversely, utilizing an under-concentrated acid leads to insufficient voltage output, sluggish performance, and premature cell failure under load. Alliance Chemical's 37% battery acid concentration prevents these failure modes, ensuring consistent electrolyte conductivity without introducing unwanted trace contaminants. Using the incorrect concentration or an unverified grade in industrial batteries can cause rapid plate degradation, internal short circuits, and complete system failure, making precise concentration control essential.\u003c\/p\u003e\n\u003cdiv class=\"chemical-profile\" data-source=\"canonical\"\u003e\n\u003ch3\u003eChemical Profile\u003c\/h3\u003e\n\u003cdl\u003e\n\u003cdt\u003eCAS Number\u003c\/dt\u003e\n\u003cdd\u003e7664-93-9\u003c\/dd\u003e\n\u003cdt\u003eChemical Formula\u003c\/dt\u003e\n\u003cdd\u003eH2O4S\u003c\/dd\u003e\n\u003cdt\u003eMolecular Weight\u003c\/dt\u003e\n\u003cdd\u003e98.08 g\/mol\u003c\/dd\u003e\n\u003cdt\u003eBoiling Point\u003c\/dt\u003e\n\u003cdd\u003e554 °F at 760 mmHg (EPA, 1998)\u003c\/dd\u003e\n\u003cdt\u003eMelting Point\u003c\/dt\u003e\n\u003cdd\u003e50.65 °F (EPA, 1998)\u003c\/dd\u003e\n\u003cdt\u003eFlash Point\u003c\/dt\u003e\n\u003cdd\u003eNon-flammable °C\u003c\/dd\u003e\n\u003cdt\u003eSpecific Gravity\u003c\/dt\u003e\n\u003cdd\u003e1.841 (EPA, 1998) - Denser than water; will sink\u003c\/dd\u003e\n\u003cdt\u003eAppearance\u003c\/dt\u003e\n\u003cdd\u003eSulfuric acid is a colorless oily liquid.
