The early gel lead-acid batteries developed by Sonnenschein (Germany) in the 1950s gained popularity in the 1970s. By mixing sulfuric acid with a silica gelling agent, the liquid electrolyte was transformed into a semi-solid paste, making the gel battery maintenance-free. In the early 1980s, AGM technology emerged, offering similar performance to gel batteries but with slightly different characteristics to meet specific market needs. Gel batteries are commonly used in both large and small UPS systems, while AGM batteries have carved out a market for starter and deep-cycle applications. Both gel and AGM batteries are part of the valve-regulated lead-acid (VRLA) family, eliminating the maintenance requirements of traditional flooded lead-acid batteries.
