本标准规定了永久安装在建筑物、构筑物或场所中的密封二次电池（阀控或气密）的安装、维护、测试和更换要求，并提供了指南。本标准涵盖标称电压为24 V或更高、容量超过10 a.h（1小时）的二次电池。它包括由铅酸电池和碱性电池（如镍镉电池）组成的电池。本标准涵盖了直流系统组件的要求，其中电池是直流系统的一部分，这些组件构成直流系统的一个重要部分。本标准仅适用于密封电池。AS 3011.1和AS 2676.1涵盖了通风单元的安装和维护。

This Standard sets out requirements and provides guidance for the installation, maintenance, testing and replacement of sealed secondary batteries (either valve-regulated or gastight) permanently installed in buildings, structures or premises. 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. It 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, where these 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 by AS 3011.1 and AS 2676.1.
