VRLA Battery
VRLA is the valve-regulated lead-acid battery which is also termed as a sealed lead acid battery that comes under the classification of the lead-acid battery. This is considered through a specific quantity of electrolyte which gets absorbed in a plate extractor or it will develop into a gel-like consistency thus balancing both the positive and negative plates. Because of this recombination of oxygen happens in the cell and the existence of the relief valve which keeps up battery fillings that self- regulates the battery cell positions.
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. In the same way, the VRLA battery also has a similar kind of chemistry, and the electrolyte in this kind of battery is immobilized.
In AGM (Absorbed Gel Matt) type of VRLA battery, the electrolyte is in fiberglass matt type, whereas in gel kind of batteries, it is in the form of a paste. At the time of cell discharge, diluted acid and the lead in the battery goes through some chemical reaction where it delivers water and lead sulfate. And when the discharge process is continued, the water and lead sulfate are again formed into acid and lead.
In the entire lead-acid type of batteries, the charging current has to be in synchronization with the battery ability so that the energy gets absorbed. When the value of the charging current is more, then the electrolysis process takes place which decomposes water as O2 and H2. When both these gases are escaped, then there has to be continual addition of water into the battery.
VRLA Life Cycle Calculation
In the VRLA battery life cycle, the battery undergoes deep discharge when the primary power sources that are used are solar, golf carts, and others. Then the battery gets again recharged thus following the discharge to get back to its ability so that it is used again and again. Whereas in a conventional cycle, the cycle gets repeated again.
This causes increased stress on the positive plate where it causes the paste to drop from the grid section. So, for these kinds of applications, there is a technology termed as a deep cycle service. This is developed by AGM battery which is designed specially to deliver enhanced life cycles for a regular cycle and deep applications. In order to enhance the cycle life, this technology is included with a positive paste type of formula.
