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 functions by means of an internal oxygen cycle (or oxygen-recombination cycle)\. During the latter stages of charging and overcharging of the positive electrode, oxygen is evolved.
The valve-regulated lead-acid (VRLA) battery is a type of lead-acid battery that requires no replenishment of the water content of the electrolyte solution and does not spill liquids. It can be used in any desired orientation.
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.
VRLA batteries can be substituted in virtually any flooded lead-acid battery application (in conjunction with well-regulated charging), as well as applications where traditional flooded batteries cannot be used. Because of their unique features and benefits, VRLA batteries are particularly well suited for:
Because of calcium added to its plates to reduce water loss, a sealed AGM or gel battery recharges more quickly than a flooded lead–acid battery of either VRLA or conventional design. Compared to flooded batteries, VRLA batteries are more vulnerable to thermal runaway during abusive charging.
