In short, a sealed lead-acid battery uses a reversible chemical reaction between lead plates and sulfuric acid to produce electricity. Charging reverses this reaction.
A sealed lead acid (SLA) battery, also known as a valve-regulated lead-acid (VRLA) battery, is a type of lead-acid battery that is sealed to prevent the escape of electrolyte. It works through a reversible electrochemical process. When the battery is discharging (supplying power), the lead plates undergo chemical reactions. The lead dioxide (PbO2) positive plate reacts with sulfuric acid (H2SO4) and electrons from the negative plate, forming lead sulfate (PbSO4) and water (H2O). The negative plate, made of lead (Pb), also transforms into lead sulfate (PbSO4) as it releases electrons. This electron flow generates electricity. During charging, the process reverses. An external electrical current forces the chemical reaction in the opposite direction, converting the lead sulfate back into lead dioxide and lead, and replenishing the sulfuric acid. The water produced during discharge helps keep the plates moist, which is crucial for operation. The battery is "sealed" because the water loss is minimal, and any gases produced during overcharging are recombined internally. Unlike traditional lead-acid batteries, SLA batteries don't require regular maintenance or electrolyte top-ups.
