The U.S. Department of Energy (DOE) reports the valve-regulated lead acid (VRLA) battery is a closed system in which the quantity of electrolyte is limited, but gases resulting from energy production are recombined to be reused instead of being released to the atmosphere. There is no need to add water to this type of battery because the electrolytes are recycled.
Introduction
The DOE sponsored research on the VLRA battery, seeking a device to store electric energy. The department was looking for something to store electric energy when demands were low and then deliver it during peak periods without difficulty. Because of its high performance, durability and ability to work requiring little maintenance, the VLRA battery was considered a success.
History
In 1978 automobiles started using the VRLA battery for starting, lighting and ignition purposes. Because of its availability and that it required little maintenance, it was used in the late 1980s and early 1990s in prototype and limited-production electric vehicles.
Benefits
The inexpensive nature of VRLA batteries has contributed to the reduced cost of electric vehicles and is helping with their sales in various markets. Its electrode materials and thermoplastic case is also recyclable.
