What type of battery is generally fitted in a UPS?
A battery is an electrochemical device that stores energy at one time for use at another. The energy is stored in chemical form and converted to electrical form during discharge. Batteries come in all sizes and shapes and are used to power everything from flashlights to space probes and satellites. There are only a few types used for UPS battery banks. The UPS battery may furnish power to the inverter for a few seconds, many minutes, or hours. The battery capacity is determined by the amount of power the inverter and its load require during that time. The cell / block is the basic building brick for a battery. Combined cells / blocks in series sums their individual output voltage and delivers the same current as a single cell/ block at the increased voltage. Paralleling cells / blocks delivers the sum of their currents at the voltage of a single cell / block. UPS system battery banks are parallel – series combinations that deliver from a few amperes to several thousand amperes. A cell
