This guide describes methods for selecting the appropriate type of valve-regulated, immobilized-electrolyte, recombinant lead-acid battery for any of a variety of potential stationary float applications. Installation, maintenance, sizing, and consideration of battery types other than valve-regulated lead-acid batteries, are beyond the scope of this guide. Design of the dc system and sizing of the dc battery charger(s) are also beyond the scope of this guide. New IEEE Standard - Superseded. Superseded by IEEE Std 1189-2007. Methods for selecting the appropriate type of valve-regulated, immobilized-electrolyte, recombinant lead-acid battery for any of a variety of potential stationary float applications are described.
