What is valve regulated lead acid (VRLA) battery?

Valve Regulated Lead Acid (VRLA) Batteries are popularly termed as maintenance free lead acid batteries. Each cell in VRLA battery will have a value (automating operating) to allow the gas to escape if developed by the over charging the cells and to hinder the entrance of oxygen from the air into the cell

How do valve regulated lead acid batteries work?

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.

What is a valve regulated battery?

The valve-regulated version of this battery system, the VRLA battery, is a development parallel to the sealed nickel/cadmium battery that appeared on the market shortly after World War II and largely replaced lead-acid batteries in portable applications at that time.

What is a 'valve-regulated lead-acid' cell?

Moreover, acid is immobilized in the new design and this endows the cell with the additional advantages of being ‘spill-proof’ and able to operate in any orientation (upright, on its side, or even upside down). The change to the so-called ‘valve-regulated lead–acid’ (VRLA) technology has not, however, been accomplished without some difficulty.

What are the advantages of VRLA battery?

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. Some of the advantages of VRLA cell is listed below: VRLA battery is maintenance free and no periodic water refilling is not required VRLA batteries will have longer life.

Can a lead-acid battery be sealed?

The unavoidable hydrogen evolution would cause a continuous increase of the internal pressure until the cell would be destroyed. For this reason, the lead-acid battery cannot be sealed, but has to have a valve that opens from time to time and allows the escape of hydrogen, even under normal operational conditions.
