Abstract

Sets out recommended practices for the installation, maintenance, testing and replacement of vented secondary batteries permanently installed in buildings.

Scope

This Standard sets out recommended practices for the installation, maintenance, testing and replacement of vented secondary batteries permanently installed 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 vented lead-acid cells and alkaline batteries comprising vented cells (such as nickel-cadmium cells).
This Standard covers requirements for components of the d.c. system of which the battery is a part, where these components comprise an essential part of the d.c. system.

This Standard covers vented cells only. The installation and maintenance of sealed cells are covered by AS 3011.2 and AS 2676.2.
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.
