The document provides recommendations for installation design and for installation, maintenance, and testing procedures to optimize life and performance of vented Nickel Cadmium batteries in stationary standby applications. Also provides guidance for determining when these batteries should be replaced.

The recommended practice is limited to maintenance, test schedules, and testing procedures that can be used to optimize the life and performance of VRLA batteries for stationary applications. Also provides guidance to determine when batteries should be replaced. The maintenance and testing programs described represent “the best program” based on the information reviewed at the time this document was developed. Stationary cycling applications such as those found in alternative energy applications are beyond the scope of this recommended practice.

The document covers descriptions of products, methods, and procedures relating to stationary batteries, battery electrolyte spill mechanisms, electrolyte containment and control methodologies, and firefighting considerations are provided.

The document defines the areas of recommended knowledge for installers and maintainers of stationary batteries and related systems to the extent that they affect the battery. Design of the dc system and sizing of the dc battery charger(s) are beyond the scope of this recommended practice. This document covers Lead-Acid and Nickel Cadmium battery technologies.

Storage equipment and systems connected to an EPS need to meet requirements specified in related IEEE standards. Standardized test procedures are necessary to establish and verify requirement compliance. These test procedures need to provide repeatable results at independent test locations and have flexibility to accommodate the variety of storage technologies and applications. This standard establishes test procedures for electric energy storage equipment and systems for EPS applications.

The document presents the procedures to be followed for the classification of lithium metal and lithium ion cells and batteries (see UN Nos. 3090, 3091, 3480 and 3481, and the applicable special provisions of Chapter 3.3 of the Model Regulations). 38.3.2 Scope 38.3.2.1 All cell types shall be subjected to tests T.1 to T.6 and T.8. All non-rechargeable battery types, including those composed of previously tested cells, shall be subjected to tests T.1 to T.5. All rechargeable battery types, including those composed of previously tested cells, shall be subjected to tests T.1 to T.5 and T.7.

Covers VRLA batteries, used as a reserve energy source that supports DC-powered telecommunications load equipment. Defines the proper operational use, storage conditions and test criteria initial and lifetime for VRLA cells (modules). Intended to be used to establish initial physical and performance characteristics of VRLA cells or modules, performance expectations throughout their lifetime and operations conditions for appropriate use and guidance for designers of these cells or modules.

The standard applies to a 1500 VDC limit, protection against electricity, gas emission and electrolyte. It is limited to Lead-Acid and nickel technologies in applications for telecom, PV, uninterruptable power supply (UPS), emergency lighting, power station, stationary engine starting.

This data sheet covers electrical protection and fire protection for cables and bus bars and discusses aluminum conductors, describing methods of connecting, splicing and terminating to prevent excessive heating that could result in arcing and fire.
