Lead Acid Cells and Batteries

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 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.

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 part of IEC 60896 is applicable to Lead-Acid cells and batteries which are designed for service in fixed locations and which are permanently connected to the load and to the DC power supply. Part 11 of the standard is applicable to vented types only. The object of this standard is to specify general requirements and main characteristics with corresponding test methods associated with all types and construction modes of Lead-Acid stationary batteries, excluding valve-regulated types.

Applies to all stationary Lead-Acid cells and monobloc batteries of the valve regulated type for float charge applications (i.e., permanently connected to a load and to a DC power supply), in a static location and incorporated into stationary equipment or installed in battery rooms for use in telecom, UPS, utility switching, emergency power or similar applications. The objective is to specify test methods for all types and construction of valve regulated stationary Lead-Acid cells and monobloc batteries used in standby power applications.

Applies to all stationary Lead-Acid cells and monobloc batteries of valve regulated type for float charge applications, (i.e., permanently connected to load and DC power supply), in a static location and incorporated into stationary equipment or installed in battery rooms for use in telecom, UPS, utility switching, emergency power or similar applications.

This international standard provides general information about secondary batteries used in PVES and the typical methods of test used for the verification of battery performance. This standard does not include specific information relating to battery sizing, method of charge or PVES design. NOTE: This standard is applicable to Lead-Acid and Nickel Cadmium cells and batteries. This standard will be amended to include other electrochemical systems when they become available.
