Note 2 to entry: The nominal voltage of a battery of n series connected cells is equal to n times the nominal. Note 1 to entry: The rated capacity is the quantity of electricity C Ah ampere-hours declared by the. Note 2 to entry: The capacity of a battery is the quantity of electricity C Ah ampere-hours declared by the.

Note 1 to entry: The cell is equipped with a safety device to prevent dangerously high internal pressure. Note 2 to entry: The cell does not require addition to the electrolyte and is designed to operate during its life in its.

When an IEC International Standard specifying test conditions and requirements for cells used in special applications is in conflict with this document, the former takes precedence e. IEC The following are some examples of applications that utilize the cells and batteries falling under the sc This document specifies methods for the clear identification of secondary cells, batteries, battery modules and monoblocs according to their chemistry electrochemical storage technology. The markings described in this document are applicable for secondary cells, batteries, battery modules and monoblocs with a volume of more than cm3.

The marking of the chemistry is useful for the installation, operation and decommissioning phases of battery life. Many recycling processes are chemistry spec IEC applies to the safety aspects associated with the accommodation, the arrangements of circuits and the operation of secondary valve-regulated lead-acid cells and batteries in portable appliances.

Requirements are specified which oblige the manufacturers of appliances and secondary batteries to prevent the misuse of batteries in the course of operation to provide protective measures avoiding injury to persons in case of battery failure and to provide sufficient information to user IEC applies to stationary secondary batteries and battery installations with a maximum voltage of DC 1 V nominal and describes the principal measures for protections against hazards generated from: - electricity, - gas emission, - electrolyte.

This International Standard provides requirements on safety aspects associated with the erection, use, inspection, maintenance and disposal. IEC specifies the basic requirements for secondary batteries and battery installations. The requirements regarding safety, reliability, life expectancy, mechanical strength, cycle stability, internal resistance, and battery temperature, are determined by various applications, and this, in turn, determines the selection of the battery design and technology.

In general, the requirements and definitions are specified for lead-acid and nickel-cadmium batteries. For other battery systems IEC specifies marking, designation, dimensions, tests and requirements for portable sealed nickel-metal hydride, small prismatic, cylindrical and button rechargeable single cells, suitable for use in any orientation.

This third edition cancels and replaces the second edition published in of which it constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - clause 4: addition of 2 parameters; - cla IEC specifies requirements and tests for the safe operation of secondary lithium cells and batteries used in industrial applications including stationary applications. When there exists an IEC standard specifying test conditions and requirements for cells used in special applications and which is in conflict with this document, the former takes precedence e.
