Battery manufacturing is the process of producing lead-acid and gel batteries commonly used for automobiles and electric vehicles that need long service periods and durability. Sulfuric acid (H2SO4) activates the lead elements of the lead battery resulting in the power effect. The correct effect can be obtained only with the right acid concentration. If the sulfuric acid concentration is too high, it causes corrosion of the lead.
Vaisala K-PATENTS® Teflon Body Refractometer PR-23-M measures in-line the sulfuric acid concentration in the acid inlet and recovery lines.
