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. >

The fundamental elements of the lead–acid battery were set in place over 150 years ago 1859, Gaston Planté was the first to report that a useful discharge current could be drawn from a pair of lead plates that had been immersed in sulfuric acid and subjected to a charging current, see Figure 13.1.Later, Camille Fauré proposed the concept of the pasted plate.
Lead Acid Battery Example 1. A lead-acid battery has a rating of 300 Ah. Determine how long the battery might be employed to supply 25 A. If the battery rating is reduced to 100 Ah when supplying large currents, calculate how long it could be expected to supply 250 A. Under very cold conditions, the battery supplies only 60% of its normal rating.
In all cases the positive electrode is the same as in a conventional lead–acid battery. Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles.
