Battery Electrolyte

Critical For Operation

Charging System

Enables electrochemical reactions within the battery to generate and store electrical energy for engine starting and vehicle systems.

Battery electrolyte is a mixture of sulfuric acid and water that fills the cells of a lead-acid battery. It facilitates the chemical reaction that produces electrical current. Over time, electrolyte can evaporate or leak, reducing battery performance and lifespan.
