The standard specifies marking, tests and requirements for sealed nickel cadmium prismatic secondary single cells.

The standard specifies marking, designation, dimensions, tests and requirements for vented Nickel Cadmium prismatic secondary single cells.

The standard specifies marking, designation, dimensions, tests and requirements for vented Nickel Cadmium prismatic secondary single cells where special provisions have been made in order to have partial or, under very specific conditions, full gas recombination.

The standard provides electrical and mechanical requirements for liquid-immersed distribution and power transformers, and autotransformers and regulating transformers; single- and polyphase, with voltages of 601 V or higher in the highest voltage winding, are set forth. It is basis for the establishment of performance, and limited electrical and mechanical interchangeability requirements of equipment are described, and for assistance in the proper selection of such equipment.

The document presents general requirements that Telcordia and participating industry representatives view as applicable to large format non-aqueous rechargeable lithium batteries to replace or interoperate with conventional batteries (i.e., Lead-Acid, nickel-based); function seamlessly with DC power plants; and provide reliable backup power to load equipment in a network environment of a typical telecommunications service provider.

The document provides a 3-level system of VRLA String Safety and Performance Criteria based on Telcordia generic requirements documents. The VRLA string criteria levels are defined as follows: ? Level 1, Safety and Minimal Operability – minimum acceptable level of compliance needed to preclude hazards and degradation of the network facility and hazards to personnel, and needed to ensure battery operability at the installation time in controlled environments.

Safety standard for stationary batteries for energy storage applications, non-chemistry specific and includes electrochemical capacitor systems or hybrid electrochemical capacitor and battery systems. Includes requirements for unique technologies such as flow batteries and sodium beta (i.e., sodium sulfur and sodium nickel chloride). Includes construction requirements, tests and production tests. Also includes requirements for cells used in these systems such as lithium-ion, nickel, Lead-Acid and includes sodium beta and flow battery requirements.

1.1 These requirements cover inverters, converters, charge controllers, and interconnection system equipment (ISE) intended for use in stand-alone (not grid-connected) or utility-interactive (grid-connected) power systems. 1.2 For utility-interactive equipment, these requirements are intended to supplement and be used in conjunction with the Standard for Interconnecting Distributed Resources With Electric Power Systems, IEEE 1547, and the Standard for Conformance Test Procedures for Equipment Interconnecting Distributed Resources with Electric Power Systems, IEEE 1547.1.

This standard applies to electrolytes and their components when used in vented nickel-cadmium cells. These electrolytes are used: for filling cells supplied without filling electrolyte, and/or, for refilling cells if change of electrolyte is required, and/or, if the operating electrolyte needs to be topped up with water, provided no specific recommendations from the manufacturer are available.
