Advantages of valve-regulated lead-acid batteries

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 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

Why is a valve regulated battery necessary?

The widespread adoption of valve-regulated lead–acid batteries is due to the drive toward increased convenience through eliminating the need for water maintenance and avoiding the release of acid-carrying gases.

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.

What function does a lead-acid battery perform?

Lead–acid batteries are employed in a wide range of applications, each with its unique duty cycle. In internal-combustion engine vehicles, the battery provides a quick pulse of high-current for starting and a lower, sustained current for other purposes. The battery remains at a high state-of-charge for most of the time.

What are the disadvantages of valve regulated batteries?

Disadvantages of valve-regulated batteries The major complication with the use of VRB tech nology is that very accurate control must be placed on the charging regime.
