One-Way, Pressure-Relief Valves A critical feature of any VRLA battery is the quality of the seal-ing valve. Not only must the valve safely release excessive pressure and gas, but it must also keep the cell from being contaminated by the atmosphere. Oxygen contamination will discharge and eventually ruin a VRLA battery. Our valves

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.
Development of Sealed Lead-Acid Batteries (1957): West Sunshine Company introduced gel-sealed lead-acid batteries, marking the birth of practical sealed lead-acid batteries. Lead-Calcium Alloy (1960s): The United States' Gates Company invented the lead-calcium alloy, which further improved sealed lead-acid batteries' development.
The process is the same for all types of lead-acid batteries: flooded, gel and AGM. The actions that take place during discharge are the reverse of those that occur during charge. The discharged material on both plates is lead sulfate (PbSO4). When a charging voltage is applied, charge flow occurs.
Do not install any lead-acid battery in a sealed container or enclo-sure. Hydrogen gas from overcharging must be allowed to escape. Always use a reliable, temperature-sensing, voltage-regulated, automatic charger. Because SVR batteries have immobilized electrolyte, they cannot spill or leak, even if punctured.
It does not require the addition of acid or water during its service life. Here are the basic characteristics of a VRLA battery: Sealed Structure: VRLA batteries are constructed with a sealed design, which means they do not have caps or openings for adding water or acid.
Our VRLA batteries are designed to be “acid-starved.” This means that the power (sulfate) in the acid is used before the power in the plates. This design protects the plates from ultra-deep discharges. Ultra-deep discharging is what causes life-shortening plate shedding and accelerated positive grid corrosion which can destroy a battery.
