Chemical Profile

Product Overview

Sulfuric Acid 37% - Battery Acid is a high-purity, colorless liquid formulation designed primarily for use in lead-acid battery systems. Chemically known as H2SO4 or Oil of Vitriol, this solution provides the precise acidity required for efficient electrochemical energy storage. Beyond battery applications, it serves as a reliable agent for pH adjustment, neutralization, and metal processing in industrial environments.

Manufactured to strict specifications, this 37% solution ensures consistent specific gravity and low impurity levels, which are critical for maximizing battery life and preventing contamination in chemical processes. It is compatible with standard corrosion-resistant materials such as HDPE and glass. Whether used for battery maintenance or chemical synthesis, this product delivers the stability and density professionals require.

Common Applications

Lead-Acid Battery Maintenance: Primary fluid used to replenish or replace electrolyte solutions in automotive, marine, and stationary battery systems.
Industrial pH Control: Used to lower pH in wastewater treatment and process streams to meet discharge compliance or process requirements.
Metal Processing: Effective for pickling and surface preparation to remove oxidation and scale from metals before finishing.
Chemical Synthesis: Acts as a reactant or catalyst in the production of fertilizers and specialty chemicals.
Laboratory Use: Reliable reagent for titrations and general laboratory acidification.

Safety Precautions

Sulfuric Acid 37% is highly corrosive and causes severe skin burns and eye damage. Proper Personal Protective Equipment (PPE) is mandatory, including chemical-resistant gloves, splash goggles, and face shields. Use only in well-ventilated areas or fume hoods. Always add acid to water; never add water to acid to prevent violent exothermic reactions.

Store in a cool, dry place in corrosion-resistant containers (HDPE, glass). Keep away from incompatible materials such as bases, organic compounds, and reducing agents. In case of contact, immediately flush the affected area with water for at least 15 minutes and seek medical attention. Refer to the Safety Data Sheet (SDS) for detailed handling and emergency instructions.
