Introduction

This standard gives information about the safety and health protection of persons when applying

secondary batteries, which are used for DC power supply systems in portable appliances. Therefore the

standard applies for commercially available secondary batteries and battery systems according to the

requirements of the “Low Voltage Directive”.

In the European countries similar relevant standards or specifications or parts of it exist, which shall be

taken into account and will be replaced by this new standard.

In certain portable appliances or toys the discharge of both primary and secondary cells or batteries is

possible. In case of interchange ability of these cells or batteries the standards for primary batteries of the

EN 60086 series, Parts 1 to 5, shall have preference.
1 Scope

This standard applies to the safety aspects associated with the accommodation, the arrangements of

circuits and the operation of secondary 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 users.
