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?

The Valve Regulated Lead Acid (VRLA) Battery is a type of rechargeable lead-acid battery. It is a fully maintenance-free and complete sealed battery. They are also commonly known as Sealed Battery (SLA). Injection of water or electrolyte not required for this type of battery.

What is the basic working principle of VRLA battery?

The basic working principle of VRLA battery can be explained as follows: As lead acid kind of batteries is included with lead plates serving as electrodes, immersed in the electrolyte that has liquid kind of sulphuric acid.

What is the difference between a lead acid battery and a VRLA battery?

As lead acid kind of batteries is included with lead plates serving as electrodes, immersed in the electrolyte that has liquid kind of sulphuric acid. In the same way, the VRLA battery also has a similar kind of chemistry, and the electrolyte in this kind of battery is immobilized.

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.

Do VRLA batteries need acid or water?

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.
