Despite their century-long history, lead-acid batteries continue to be used in a wide range of modern applications, including electric vehicles (EVs). They’re cost-effective, reliable, and have a long lifespan if properly maintained. Nevertheless, lead-acid batteries do face some limitations when implemented in electric vehicles (EVs).
Their bulk and weight represent one of the most significant drawbacks of lead-acid batteries.
They’re relatively heavy and bulky, which makes them unsuitable for use in smaller EVs or hybrids. In comparison to other battery technologies, they exhibit a reduced energy density, implying that they are unable to retain as much energy per unit of weight or volume.
Despite these limitations, lead-acid batteries continue to be used in some EVs, primarily in larger vehicles like buses, trucks, and forklifts. These applications require less energy density and can benefit from the reliability and cost-effectiveness of lead-acid batteries.
