    Abstract - (Show below) - (Hide below)

    Part 2 sets out recommended practices for the installation, maintenance, testing and replacement of sealed secondary batteries permanently installed in buildings.

    Scope - (Show below) - (Hide below)

    This Standard sets out recommended practices for the installation, maintenance, testing and replacement of sealed secondary batteries (either valve-regulated or gastight) located in or on buildings. It also provides guidance to determine when batteries should be replaced.This Standard covers secondary batteries with a nominal voltage of 24 V or greater, and a capacity exceeding 10 A.h at the 1 h rate and includes batteries comprising lead-acid cells and alkaline cells (such as nickel-cadmium cells).This Standard covers requirements for components of the d.c. system of which the battery is a part, wherethese components comprise an essential part of the d.c. system.This Standard covers sealed cells only. The installation and maintenance of vented cells are covered byAS 3011.1 and AS 2676.1.NOTE: Requirements specifically applicable to the design and installation of extra-low voltage (d.c.) power supplies that are used by telecommunications carriers in the provision of public telecommunications networks are given in AS 3015 (Int)-1991, Electrical installations- Extra-low voltage (d.c.) power supplies in public telecommunications networks.
