The Sealed Lead-Acid (SLA) Battery is a type of rechargeable battery that has been widely used in applications ranging from automotive and uninterruptible power supplies (UPS) to renewable energy storage and more. The origins of the lead-acid battery can be traced back to 1859, when French engineer Gaston Planté invented the first rechargeable lead-acid battery. In the 1860s, Fernand Faure, a French engineer, improved upon Planté’s design by introducing the paste technique, where lead oxide paste was applied to the plates. This significantly improved the battery’s performance and capacity, making it more practical for use in various applications
One of the key benefits of lead-acid batteries, including SLA batteries, is their recyclability. Lead-acid batteries are among the most recycled consumer products globally, with over 95% of the components (including lead and acid) being reused in new batteries. This has made SLA batteries an environmentally friendly option, despite concerns about lead exposure and pollution.
As of the 2010s and into the present day, sealed lead-acid batteries continue to be a staple in industries requiring reliable and lowmaintenance battery solutions. They remain widely used in UPS systems, telecommunications, alarm systems, and solar energy storage applications.
