The H2SO4 electrolyte concentration impacts the performance of lead-acid batteries, commonly used as car batteries. A researcher wishes to determine the optimal H2SO4 concentration for the best performance of the battery, as measured by the voltage output. Independent variable: Dependent variable:
Common Types of Battery Electrolytes
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. When we charge a lead-acid battery, lead oxide forms on the positive plate, causing the …
How to Test the Health of a Lead-Acid Battery
Testing the health of a lead-acid battery is an important step in ensuring that it is functioning properly. There are several ways to test the health of a lead-acid battery, and each method has its own advantages and disadvantages. In this article, I will discuss some of the most common methods for testing the health of a lead-acid battery.
Measuring the density and specific gravity of battery acid in lead acid ...
Due to chemical reactions during discharge, the density of the sulfuric acid electrolyte (or its specific gravity) decreases. Measuring the density of the battery acid therefore gives information about the concentration of H 2 SO 4 and the charging status of the battery. Depending on the result, the operator knows whether the battery needs ...
