A VRLA battery or Valve Regulated Lead Acid Battery is a sealed battery or maintenance-free battery. This is one type of Lead-acid rechargeable battery. The VRLA Battery does not require stringent ventilation. Also, we can mount the battery in any orientation. The ...
Valve-Regulated Lead-Acid (VRLA)
One-Way, Pressure-Relief Valves A critical feature of any VRLA battery is the quality of the sealing 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 are
Valve Regulated Lead Acid (VRLA) Batteries | Advantages
The valve present in VRLA cell acts as a safety valve which opens when the concentration of hydrogen gas inside the battery increases dangerously high. Valve-Regulated LA (VRLA) has become a popular battery for powering Electric Vehicles because of its high specific power, low initial cost, and quick charge capability, and no …
Valve Regulated Lead Acid Battery
Lead-acid batteries are made up of a succession of lead-acid cells in the same container. You see, two lead plates are suspended in a fluid-like electrolyte mixture of sulfuric acid in lead-acid cells. Sealed Lead Acid (SLA) and Valve Regulated Lead Acid (VRLA) are two distinct names for the same type of battery. Here are the features you will ...
The Role of Lead-acid Battery Safety Valve
The safety valve in a lead-acid battery plays a crucial role in ensuring the safe and efficient operation of the battery. Here are the main functions and importance of the safety valve. Pressure Regulation: Release Excess Pressure: During the charging process, lead-acid batteries can generate gases (mainly hydrogen and oxygen) due to …
The Role of Lead-acid Battery Safety Valve
In summary, the safety valve is essential for the safe operation, longevity, and reliability of lead-acid batteries by regulating internal pressure, preventing contamination, safely venting gases, and providing maintenance indications.
