A valve regulated lead acid (VRLA) battery is also known as sealed lead–acid (SLA) battery is a type of lead-acid battery. In this type of battery, the electrolyte that does not flood the battery but it’s rather absorbed in a plate separator or silicon is added to form a gel.
Handling Valve Regulated Lead Acid (VRLA) batteries requires attention to safety. Here’s a concise guide to key precautions: Ensure proper ventilation in areas with VRLA batteries to disperse gases released during charging and discharging.
Valve Regulated Lead-acid batteries do produce hydrogen and oxygen during operation. This is especially true during charging and discharging. These gases result from electrolysis of the water portion of the electrolyte by the charging current. Natural or artificial ventilation is recommended in the battery room, or area, to prevent build-up.
Explore the diverse applications of Valve Regulated Lead Acid (VRLA) batteries across various industries: Telecommunications: VRLA batteries provide crucial backup power for telecommunication systems, ensuring uninterrupted communication during power outages. They are commonly used in base stations, data centers, and telephone exchanges.
In all lead acid batteries, when a cell discharges charge, the lead and diluted sulfuric acid undergo a chemical reaction that produces lead sulfate and water. When the battery is put on the charger, the lead sulfate and water are turned back into lead and acid. The charging current is very important for this process to take place.
