Overview of Lead Acid Batteries:Lead acid batteries, also known as valve-regulated lead acid (VRLA) batteries, are the most widely used type of rechargeable battery. They have been extensively used in applications such as automotive starting, lighting, and emergency power systems. These batteries are known for their robustness, reliability, and cost-effectiveness. https://www.accord-power.com/products/

Working Principle of Lead Acid Batteries
A lead acid battery consists of two electrodes, an anode (positive plate) and a cathode (negative plate), immersed in an electrolyte solution. The electrodes are made of lead and lead dioxide respectively. During the charging process, the lead acid battery converts chemical energy into electrical energy. The anode undergoes oxidation, releasing electrons, while the cathode undergoes reduction, accepting electrons. These electrons flow through an external circuit, providing power to the connected load.

Advantages of Lead Acid Batteries for UPS
1. Cost-Effectiveness: Lead acid batteries are relatively inexpensive compared to other types of batteries, making them a popular choice for UPS applications, especially for large-scale systems.
2. Long Life and Reliability: Lead acid batteries have a long lifespan and are known for their reliability. They can withstand numerous charge-discharge cycles, making them suitable for UPS systems that require continuous operation.
3. High Energy Density: Lead acid batteries have a high energy density, which means they can store a large amount of energy relative to their size and weight. This property is crucial for UPS applications where space is often limited.
4. Widely Available: Lead acid batteries are widely available in the market, making them easy to procure and maintain.
5. Temperature Tolerance: Lead acid batteries can operate effectively over a wide range of temperatures, making them suitable for various environments.
