Vrlais an abbreviation of the valve regulated lead-acid batteries. Usually when we look at the parameters of the vrla battery, the two most important battery parameters are voltage and capacity, in addition, if we want to know more about the current detailed parameters of the VRLA battery, we also need to look at the battery's internal resistance and cycle life, battery energy, storage performance and other aspects of the specification parameters.

    from daily battery and nameplates.it, valve regulated lead acid vrla batteries main parameters including capacity, rated voltage, internal resistance, and life as well as special performance parameters and so on. These parameters not only reflect the basic performance of the battery, but also provide us with the basis for choosing and using the battery. After understanding these parameters, we can better play the advantages of VRLA batteries to provide stable and reliable power support for various application scenarios. From the market point of view, this is a widely used in various fields of energy storage equipment. It has the advantages of high sealing, low maintenance workload and long service life, so it is favored. However, for non-professionals, the main parameters of VRLA batteries may be unfamiliar. This article will carry out a detailed popularization of these parameters to help everyone better understand and use VRLA batteries.

        VRLA battery capacity parameter:

            from the battery, let's take a look at the capacity of VRLA battery parameters. Battery capacity is an important indicator of a battery's ability to store electrical energy, usually expressed in ampere-hours (Ah) or milliampere-hours (mAh). In theory, the discharge time of the battery can go to infinity, but in practice, when the battery is discharged to the termination voltage, if continued discharge may damage the battery, so the discharge time is limited. For example, a nominal 100Ah VRLA battery means that it can theoretically discharge at 10A for 10 hours, emitting a total of 100Ah of electricity.

        resistance voltage and parameters:

            in addition to the capacity of the parameters of VRLA battery and rated voltage is an important indicator. Rated voltage refers to the voltage that should be maintained at both ends of the battery under normal working conditions. For VRLA batteries, the common rated voltage is 12V, 24V and so on. When selecting a battery, it is necessary to match the appropriate battery according to the voltage requirements of the electrical equipment. In addition, the internal resistance of the VRLA battery is also a parameter that cannot be ignored. Internal resistance refers to the resistance encountered by the current passing through the inside of the battery when it is working. The smaller the internal resistance, the better the performance of the battery, because a small internal resistance means that the battery is able to convert chemical energy into electricity more efficiently. For VRLA batteries, due to the use of advanced structures and materials, their internal resistance is usually small, so they have better performance when discharging at high currents.

        life of VRLA battery and What number:

            battery life usually refers to the time it can work normally. The life of VRLA batteries is affected by many factors, such as the working environment temperature, charging and discharging mode. In the high temperature environment, the floating charge life of the battery will accelerate the decay; Overcharge or undercharge will also adversely affect the life of the battery. Therefore, when using VRLA batteries, it is necessary to pay attention to controlling the working temperature and adopting reasonable charging and discharging methods to extend the service life of the battery.

        special performance  parameter view:

            VRLA batteries, there are some specific performance parameters such as equalization charging voltage, floating charge voltage and maximum charging current, etc. These parameters play a crucial role in the charging process of the battery. The balanced charging voltage refers to the voltage range that the battery needs to maintain during the charging process to ensure that the battery can be evenly charged; The floating charging voltage refers to the voltage value that the battery needs to maintain under the floating charging state. The maximum charging current limits the amount of current the battery can accept during the charging process to prevent the battery from being damaged by overcharging.

  we need to mention high power characteristics of VRLA battery. High-power batteries can release a large amount of electric energy in a short time to meet the needs of high-power devices. For VRLA batteries, their power density is an important indicator to measure their high power performance. The higher the power density, the more power the battery can output per unit volume or weight.

    valve regulated lead-acid batteries is a special type of lead-acid battery, its design and manufacturing processes focus on air tightness and liquid tightness of the battery. The shell and cover of the valve regulated lead-acid battery are usually made of ABS synthetic resin or flame-retardant plastic, which ensures the structural strength of the battery and the safe use of the battery. The positive and negative electrodes of the valve regulated lead-acid battery are coated plates with special lead-calcium alloy grating, which can increase the overpotential of the positive and negative gas evolution (H2 and O2) and reduce the gas evolution during charging. In addition, the separator is made of high-quality ultrafine glass fiber cotton (felt), which provides a channel for the diffusion of oxygen precipitated on the positive electrode to the negative electrode. This design allows the gas generated inside the battery to be effectively managed and controlled during operation.

    valve regulated lead-acid batteries are the most remarkable characteristic is that it is equipped with safe and reliable pressure reducing valve. When the internal pressure of the battery exceeds a predetermined value, the pressure reducing valve will automatically open to release the accumulated gas inside, so as to prevent the battery from exploding due to excessive internal pressure. When the internal pressure is reduced, the pressure reducing valve will automatically close to prevent external air from entering the battery and maintain the tightness of the battery. This design eliminates the need to refill the electrolyte during the normal life of the valve regulated lead-acid battery, reducing maintenance costs and improving battery safety. Safety is not the only advantage of valve regulated lead-acid batteries. It also has the characteristics of good high current discharge performance, small self-discharge current, no leakage, no acid fog, no corrosion equipment and no injury. In addition, the life of the valve regulated lead-acid battery is also relatively long, under the right conditions, its service life can reach 10 to 15 years.

    In daily use, the valve regulated lead-acid batteries is a kind of excellent performance, safe and reliable lead-acid battery, its emergence has greatly promoted the development of related fields, and brought convenience to people's life and work. Because of its excellent performance and wide application fields, valve regulated lead-acid batteries have become an indispensable part of UPS power supply, communication base station backup power supply, and power industry substations, transmission and distribution systems. At the same time, in the energy storage equipment of new energy power stations, valve regulated lead-acid batteries also play an important role.
