Customer ServiceA VRLA, or Valve Regulated Lead Acid battery is a rechargeable lead acid battery. that doesn''t require regular maintenance like topping off water levels, VRLA batteries are sealed and do not allow for the addition or loss of liquid. Its design includes a safety valve that will open only if internal pressure rises to a dangerous level. Types of VRLA Batteries. VRLA
Customer ServiceDuring discharge, the PbO2 (lead dioxide) of the positive plate becomes PbSO4 (lead sulphate); and the Pb (spongy lead) of the negative plate becomes PbSO4 (lead sulphate). This causes a reduction of the specific weight of the electrolyte, as the sulphuric acid contained in the electrolyte passes to the plates during discharge.
Customer ServiceIn the charging process we have to pass a charging current through the cell in the opposite direction to that of the discharging current. The electrical energy is stored in the form of chemical form, when the charging current is passed. lead acid battery cells are capable of producing a large amount of energy.
This dominance is particularly evident in the field of Uninterruptible Power Supplies (UPS). A Valve Regulated Lead-Acid Battery (VRLA battery) is a type of lead-acid battery characterized by its sealed, maintenance-free design. It does not require the addition of acid or water during its service life.
As lead acid kind of batteries is included with lead plates serving as electrodes, immersed in the electrolyte that has liquid kind of sulphuric acid. In the same way, the VRLA battery also has a similar kind of chemistry, and the electrolyte in this kind of battery is immobilized.
Following are some of the important applications of lead – acid batteries : As standby units in the distribution network. In the Uninterrupted Power Supplies (UPS). In the telephone system. In the railway signaling. In the battery operated vehicles. In the automobiles for starting and lighting.
The construction of a lead acid battery cell is as shown in Fig. 1. It consists of the following parts : Anode or positive terminal (or plate). Cathode or negative terminal (or plate). Electrolyte. Separators. Anode or positive terminal (or plate): The positive plates are also called as anode. The material used for it is lead peroxide (PbO 2).
Moreover, acid is immobilized in the new design and this endows the cell with the additional advantages of being ‘spill-proof’ and able to operate in any orientation (upright, on its side, or even upside down). The change to the so-called ‘valve-regulated lead–acid’ (VRLA) technology has not, however, been accomplished without some difficulty.
