This dominance is particularly evident in the field of Uninterruptible Power Supplies (UPS). A Valve Regulated Lead-Acid Battery (VRLA battery) is a type of lead-acid battery characterized by its sealed, maintenance-free design. It does not require the addition of acid or water during its service life.
Discover the working principle of Valve Regulated Lead Acid (VRLA) batteries: Basic Operation: VRLA batteries operate on the principle of electrolysis. Within the sealed battery, two lead plates immersed in a sulfuric acid solution facilitate a chemical reaction. One plate is coated with lead dioxide, while the other is made of spongy lead.
B. Culpin, in Encyclopedia of Electrochemical Power Sources, 2009 Valve-regulated lead–acid batteries operating under the oxygen cycle have had a major impact on the battery market over the last 25 years.

Discover® valve-regulated Deep Cycle AGM and EV Traction Dry Cell batteries have the features and benefits that matter to your customers: Can be used in any orientation in float service (except upside down). To avoid premature loss of capacity (approx. 15%) and life, upright orientation is highly recommended for constant deep discharge applications
The first VRLA batteries had the sulphuric acid electrolyte immobilized as a gel by the addition of 5–8 wt% of fumed silica. Unlike a traditional wet-cell lead–acid battery, these ‘gel-type’ batteries do not need to be kept upright and virtually eliminate the electrolyte evaporation and spillage common to the wet-cell battery.
