Valve Regulated Lead Acid Battery: Manufacture, Features, Advantages, Usage and Selection Guide
Valve regulated lead acid (VRLA) battery, also known as a maintenance-free lead acid battery or an absorbent glass mat (AGM) battery, is a type of rechargeable power storage device widely used in various start-stop car battery applications. This article aims to provide comprehensive information about the manufacturing process, characteristics, advantages, usage methods and how to choose this product.
The producti valve regulated lead acid battery on of VRLA batteries involves several key steps. First, lead oxide is mixed with dilute sulfuric acid to form the active material paste. Then the paste is applied onto expanded metal grids for positive plate production and casted grids for negative plates. These plates are then cured and assembled into cells along with separators soaked in electrolyte solution containing sulfuric acid and water. Finally, the cells are sealed with pressure relief valves and safety vents to prevent any gas leakage.
VRLA batteries have several notable featur Absorbent glass mat (AGM) battery es that make them popular in different industries. Firstly, they are valve regulated which means that they do not require replenishment of water or electrolyte during their service life. This eliminates the need for regular maintenance tasks associated with traditional flooded lead-acid batteries such as checking fluid levels or adding distilled water periodically.
Secondly, VRLA batteries use an AGM technology where the electrolyte is absorbed by fiberglass separators instead of freely flowing liquid electrolyte fo SLA battery und in conventional batteries. This design enhances efficiency as it allows a higher surface area contact between active materials on both sides of the separator resulting in improved energy density and reduced internal resistance.
Lastly but significantly important aspect of VRLA battery technology lies within its ability to be mounted at any angle without risk of spilling hazardou Maintenance-free lead acid battery s substances since all gases generated during charge/discharge cycles inside these technologically advanced sealed cases can be recombined within its structure thus eliminating release through pressure relief valves.
VRLA batteries offer several advantages over other types of batteries. First and foremost, their maintenance-free nature saves both time and effort as there is no need to regularly check or add water. Additionally, the design of VRLA batteries allows for flexible installation, making them suitable for applications where space is limited or unconventional mounting positions are required.
Furthermore, VRLA batteries have a relatively low self-discharge rate compared to other battery chemistries. This means that they can retain more charge when not in use for extended periods of time, making them ideal for standby power supply applications such as emergency lighting systems or uninterruptible power valve regulated lead acid battery supplies (UPS).
One common application of VRLA batteries is in start-stop car systems where the battery must withstand frequent charge/discharge cycles caused by engine shutdowns during idle periods. The high-rate discharge capability and deep cycle endurance make this technology an excellent choice for this demanding automotive application.
ea where VRLA batteries excel is in solar inverters due to their ability to handle high current demands while maintaining stability under varying charging conditions from solar panels.
Moreover, VRLA deep cycle batteries find extensive usage in recreational vehicles (RVs), boats, wheelchairs and electric scooters providing reliable power storage with long service life.
How to Select the Product:
When selecting a valve regulated lead acid battery, several factors should be considered. Firstly,
the capacity requirements need to match the intended application’s electrical load demand
to ensure sufficient run-time between rech maintenance free deep cycle battery arging cycles.
consideration should be given to the physical dimensions and weight restrictions imposed by
the available space or required portability in case if it’s meant for mobile application like RV
or boat cruising around lakes or rivers.
the reputation of a well-established manufacturer who adheres strictly quality standards should play an important role since reliability and durability are crucial aspects when choosing any energy storage solution.
V Solar Inverter alve regulated lead acid batteries, with their maintenance-free operation, efficient design and robust performance characteristics, have become a popular choice for various valve regulated lead acid battery applications. Whether it’s providing backup power in homes or commercial buildings during electricity outages or being the energy source behind start-stop car systems or solar inverters driving clean energy initiatives, VRLA batteries continue to deliver reliable and safe power storage solutions across different industries.
