Valve-regulated lead-acid (VRLA) batteries have long been a reliable power solution in a variety of industries.
If the internal pressure becomes too high, the valve opens to release the gases and keep the battery from over-pressurizing. This sealed design not only eliminates the need for regular maintenance but also ensures that the electrolyte remains in the battery, enhancing its reliability and extending its lifespan.
The basic chemistry behind VRLA batteries is the same as that of traditional lead-acid batteries: a chemical reaction between lead plates and sulfuric acid generates electrical power. During discharge, lead dioxide (PbO2) at the positive plate reacts with sulfuric acid (H2SO4) to release electrons, creating a flow of electricity.
