VRLA Battery

VRLA Batteries are valve-controlled sealed lead-acid batteries. Valve Regulated Lead Acid Battery was born in the 1970s. By 1975, it had formed a considerable scale of production in some developed countries, and was soon industrialized and put on the market in large quantities. Although this battery is also lead-acid battery, but it has many advantages compared with the original lead-acid battery, and it is very popular among users, especially those who need to install battery supporting equipment together (or a workshop), such as UPS, telecommunications equipment, mobile communication equipment, computers, motorcycles, etc.

Because VRLA Battery is fully sealed, will not leak acid, and in charge and discharge will not be like the old lead-acid battery will have acid mist released and corrosion equipment, pollution of the environment, so from the structural characteristics of the Vrla Battery is also called closed (sealed) lead-acid battery. For the purpose of distinction, the old lead-acid battery is called the open lead-acid battery. Because the VRLA battery from the point of view of structure, it is not only fully sealed, but also has a can control the gas pressure inside the battery valve, so the full name of VRLA lead-acid battery is "valve controlled sealed lead-acid battery".
