Valve-regulated lead–acid batteries operating under the oxygen cycle have had a major impact on the battery market over the last 25 years. They differ from conventional flooded batteries in that the electrolyte level is controlled to ensure that some gaseous porosity remains in the separator.
The valve regulated lead acid (VRLA) battery is a common variant, which not only constitutes towards the largest part of the worldwide secondary battery market share but possesses high specific power, quick charge capability, and least maintenance requirement .
Oxygen-recombinant valve-regulated lead-acid (VRLA) batteries [1,2] use the same technology as flooded lead-acid batteries, but the acid electrolyte is immobilised by sealing the battery with a valve. This eliminates the need for addition of water and avoids electrolyte mix preventing stratification.
M.J. Weighall, in Encyclopedia of Electrochemical Power Sources, 2009 The development of valve-regulated lead–acid (VRLA) batteries containing absorptive glass mat (AGM) separators resulted from a highly focused venture technology program at Gates Rubber Co.
