Advantages of valve-regulated sealed lead-acid batteries

The battery has the advantages of stable voltage, reliable power supply and convenient movement. It is widely used in power plants, substations, communication systems, electric vehicles, aerospace and other departments. The main batteries are common lead-acid batteries, alkaline cadmium nickel batteries and valve-regulated sealed lead-acid batteries. Ordinary lead-acid batteries have limited use due to their short service life, low efficiency, complicated maintenance, and acid mist pollution. They have been gradually eliminated by valve-regulated sealed lead-acid batteries.

The valve-regulated sealed lead-acid battery adopts a sealed structure as a whole. There is no gas rise and electrolyte leakage in the ordinary lead-acid battery. The use is safe and reliable, and the service life is long. It is not necessary to test the electrolyte and adjust the acid and water during normal operation. Also known as maintenance-free batteries. It has been widely used in many fields such as post and telecommunications, ship traffic, emergency lighting and so on. The alkaline cadmium nickel battery is characterized by small volume, high discharge rate, simple operation and maintenance, and long service life. However, due to its low monomer voltage, easy leakage, high cost, and easy environmental pollution, its use is limited. Used in power tools and various portable electronic devices.
