The lead-acid battery is the predominant choice for uninterruptible power supply (UPS) energy storage. Over 10 million UPSs are presently installed utilizing flooded, valve regulated lead acid (VRLA), and modular battery cartridge (MBC) systems. This paper discusses the advantages and disadvantages of these three lead-acid battery technologies.
LEAD ACID BATTERIES : 5.1 The batteries shall be made of closed type lead acid cells of very low internal resistance having high cycling capability ,moderate size, high service life minimum 20 years, excellent performance for both low & high rates of discharge, rigid cell plates design type manufactured to conform to
Although alternative energy storage technologies such as fuel cells, flywheels, lithium ion, and nickel cadmium batteries are being explored (see White Paper 65, Comparing Data Center Batteries, Flywheels, and Ultracapacitors for more details) data center and network room UPS systems almost exclu-sively utilize lead-acid batteries.
harging characteristics.Charging in SeriesLead-acid batteries are strings of 2 volt cells connected in seri s, commonly 2, 3, 4 or 6 cells per battery. Strings of Power-Sonic batteries, up to 48 volts and higher, may be charged in series safely and eficiently. However, as the number of batteries in series increases, so does the po
Characteristics of the vented battery include the following: VRLA batteries have been utilized for approximately 20 years. This technology offers a higher power density and lower capital costs than traditional vented cell solutions. VRLA batteries are typically deployed within power systems rated below 500 kVA.
According to the Concorde Battery Technical Information Library, “The battery will reach a moderate internal temperature (approximately 260 °F / 126 °C) at which point the water in the electrolyte vaporizes and the battery vents steam. As the separator is glass, it is unaffected by this temperature.
