Lead–acid batteries are comprised of a lead-dioxide cathode, a sponge metallic lead anode, and a sulfuric acid solution electrolyte. The widespread applications of lead–acid batteries include, among others, the traction, starting, lighting, and ignition in vehicles, called SLI batteries and stationary batteries for uninterruptable power supplies and PV systems.
A large battery system was commissioned in Aachen in Germany in 2016 as a pilot plant to evaluate various battery technologies for energy storage applications. This has five different battery types, two lead–acid batteries and three Li-ion batteries and the intention is to compare their operation under similar conditions.
In sealed lead-acid batteries (SLA), the electrolyte, or battery acid, is either absorbed in a plate separator or formed into a gel. Because they do not have to be watered and are spill-proof, they are considered low maintenance or maintenance-free. SLAs typically have a longer shelf life than flooded batteries and charge faster. However, they can be more expensive.
