Valve Regulated Lead Acid (VRLA) Batteries or sometimes called "Valve Regulated Lead Acid batteries," are batteries that have been specially made to regulate the acid flow through the battery case, stopping the battery from overcharging and discharging when necessary. A Valve Regulated Lead Acid battery, also called a "vented lead-acid battery," is a kind of lead sulfate battery characterized by an extremely limited amount of sulfuric acid in a lead plate separator. Because this type of battery has a limited amount of sulfuric acid available, the battery has a very slow charge rate. When a battery is charging, the valve regulates the battery's charge to ensure that the battery does not overcharge. As the battery charges, the sulfuric acid is used up by the battery's natural chemical self-discharge cycle. The battery then reverts to its self-discharge cycle, reducing the battery's total capacity.
Valve Regulated Lead Acid (VRLA) Batteries are battery packs that contain a regulation valve between the battery tray. There are a few different Valve Regulated Lead Acid Batteries on the market today. The most popular is the original VOIP Valve Regulated Lead Acid Batteries that is the standard equipment for many businesses. They are inexpensive, have a long life span, and are very reliable. In addition to the standard valve regulators, there are also Valve Regulated Lead Acid Batteries for commercial use that have larger spillages, greater capacity for high-performance vehicles and for use in backup applications in industries.
There are a few different Valve Regulated Lead Acid (VRLA) Batteries that one can choose from. There are the gel cells that contain nozzles inside them, which allows for the liquid inside to drain into the separator when the battery is fully charged. There are also the tubular cells, which have sloped sides and vents at the top and bottom. This battery has two venting options; one concentrates the gas inside the cells while the other directs it out to the sides of the tubular cell. These two types of Valve Regulated Lead Acid Batteries have their own advantages and disadvantages.
Gelling cell leads acid batteries are good because they allow for more efficient use of the electrolyte. It takes more energy to charge a battery when there is more than just water in it. Since water is present in both types, the process is much more efficient. When using gel cell technology, there is not nearly as much waste created as there would be with other battery types.
However, gelled batteries acid batteries take longer to charge and release more energy when fully charged. This means that the user will be spending more time getting the battery fully charged than one would use the gel cell technology. This could pose a safety risk especially for those who do not know how to properly handle batteries like this.
Valve Regulated Lead Acid Batteries can be designed in a way that allows for either type of technology to be used for charging a battery.
The valve batteries are becoming more popular because they are cheaper and allow for the same levels of efficiency as other types of battery technology. However, due to their efficiency, they also use more electrolytes than other types of batteries.
