What is Lead Acid Battery? Introduction: • A battery is a storage device which stores power. • As shown in the figure-1, it contains six cells with each having 2V value. • Materials used are led peroxide (PbO2), sponge led (Pb) and dilute sulfuric acid (H2SO4) • Positive plate of lead acid battery is made of PbO2 which is dark brown hard and brittle substance. • Negative plate of lead acid battery is made of pure led in soft sponge condition (Pb). • Here H2SO4 uses water to acid ratio of 3:1
