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 .
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.
Charge profiles for new 6 V 100 Ah valve-regulated lead–acid (VRLA) batteries at different charge voltages and temperatures. Reproduced from Culpin B (2004) Thermal runaway in valve-regulated lead-acid cells and the effect of separator structure. Journal of Power Sources 133: 79–86; Figure 1. Figure 9.
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.
The VRLA battery became a practical proposition only when it was discovered that glass microfiber was a suitable separator because of its gas-transfer properties and other important features such as high acid absorbency, high chemical purity, oxidation stability, and acceptable manufacturing cost.
It has structural and chemical characteristics with implications well beyond physical separation of the plates. During normal operation of the VRLA battery, oxygen generated at the positive plate travels through the separator to be recombined at the negative plate.
