          The characteristics of the various battery energy systems available are described so that users can select the system best suited to their requirements. This guide also describes how the rectifier and the inverter components of the uninterruptible power system (UPS) can relate to the selection of the battery system.<br />\n

          This guide is intended to assist users who select battery systems for uninterruptible power systems (UPS).<br />\n
          The guide informs users of the characteristics of the various battery energy systems available so they can select the system best suited to their requirements. This guide does not place any restrictions on the rectifier or inverter components of the UPS. It does, however, describe how those components can relate to the selection of the battery system.<br />\n
          This guide divides the available technologies into the following two main categories:<br />\n
          a) Lead-acid batteries, which include both vented (ßooded) and valve-regulated (sealed) constructions<br />\n
          b) Nickel-cadmium batteries For each category, both the technology and the design of the battery are described in order to facilitate user selection. The specific advantages for particular applications are also listed.<br />\n
          Several battery designs are available to the UPS user. Each design has advantages and disadvantages, all of which should be considered when selecting a battery.

          Various battery systems are discussed so that the user can make informed decisions on selection, installation design, installation, maintenance, and testing of stationary standby batteries used in uninterruptible power supply (UPS) systems. This guide describes how the UPS battery charging and converter components can relate to the selection of the battery systems. Design requirements of the UPS components are beyond the scope of this document. Battery back-up systems for dc-output rectifiers are also beyond the scope of this document.<br />\n

Design requirements of the UPS components are beyond the scope of this document. Battery back-up systems for dc-output rectifiers are also beyond the scope of this document. While this document applies to all UPS systems, it may be impractical to implement some of its guidance and recommendations with small, self-contained systems, such as products intended to back up individual personal computers. This guide divides the available technologies into the following three main categories: ? Vented lead-acid batteries (VLA) ? Valve-regulated lead acid (VRLA) ? Ni-Cd batteries (Ni-Cd) For each category, the technology and the design of the battery are described in order to facilitate user selection. The specific advantages for particular applications are also listed.<br />\n
          This guide is intended to assist those involved with battery systems for uninterruptible power supply systems. Proper design, installation, and maintenance will enable the user to manage the battery system for optimum operation and results.

          This guide divides the available technologies into the following two main categories:<br />\n
          a) Lead-acid batteries, which include both vented (ßooded) and valve-regulated (sealed) constructions<br />\n
