Telcordia Generic Requirements for Vented Lead-Acid Batteries

Document Number GR-232
Issue Number 04
Issue Date Jul 2023
Replaces TR-EOP-000232 Issue01

    This Generic Requirements document (GR) covers requirements for various types of vented lead-sulfuric acid enclosed-jar type storage cells (pure lead and lead alloy) of 100 ampere-hours capacity and larger or for high-rate vented cells rated 400 watts/cell or more. At the discretion of the user, the requirements can be applied to vented lead-acid engine start batteries with capacities as low as 25 ampere-hours. It does not cover the manufacture of the product, but is intended to define the characteristics of the end product. In all respects where specifics are not covered in this document, the product shall be in accordance with the standard practice of the supplier.

    Vented Lead-Acid (VLA) batteries have for many decades been the most widely deployed type of batteries in telecommunications central offices. Recently, competing technologies have been commercially launched and many hold great promise. When compared to VLA, these competing technologies offer advantages in some areas and disadvantages in others. As all energy storage applications rapidly expand to complement solar and wind generation, building and fire codes have been revised to address increased fire and safety concerns. This code-driven focus on battery safety underscores the need to maintain well-designed, safely installed and properly operated telecommunications battery plants. For the near future, despite competing technologies in the marketplace and on the horizon, VLA batteries will continue to be the cornerstone of energy storage in telecommunications central offices as well as many data centers.

    This GR document does not address the requirements of Valve-Regulated Lead-Acid (VRLA) type batteries. Requirements for VRLA batteries can be found in GR-4228-CORE, Telcordia Valve-Regulated Lead-Acid (VRLA) Battery String Certification Levels Based on Requirements for Safety and Performance.

    Proper safety precautions shall be followed for all tests conducted. Proper safety precautions are necessary to prevent injury. Use of these test procedures is solely at the user's risk.

    The products covered in this document are of the lead-sulfuric acid enclosed-jar type storage cell with pasted-plate lead/lead-alloy grid elements. The cells are intended for essentially continuous float operation over the lifetime of the battery in battery strings containing six or more cells. Those battery strings are required to be available for infrequent discharges of durations ranging from a few minutes to several hours; the discharges will generally be followed by recharge at constant voltage and then by more continuous float operation.

    The manufacturer should be prepared for product inspections, at the discretion of the purchaser, to monitor the continuing conformance to the requirements of this document.

    Reasons for GR-232-CORE, Issue 4

    This document includes a new Electrical Safety Section which includes an objective for listing by a US Department of Labor Occupational Safety and Hazard Administration (OSHA) Nationally Recognized Testing Laboratory (NRTL).
