61955 IEC:1998 (E) - 5 - Battery design considerations investigated mandatory design convergence; alternative design solutions including patent research; clarified information in existing documentation relating to terminal design Battery compartment design considerations published battery compartment design guidelines to limit the problems associated with the reverse placement of a battery in multi-cell (three or more) applications; promoted the safe positioning of compartments and foolproofing access. Consumer information promoted the safe handling of batteries by publishing a consumer information leaflet including cautionary advice. EN: 4 General N 4.1 Battery compartment guidelines NLl The battery compartment guidelines published in annex B of this report are intended to direct the attention of the device designer to integratea number of important features which according to battery industry resources, significantly reduce the hazards associated with batteryabuse. KAN NCH 4.2Clarification note to IEC 60086-1 In order to provide clear design options for both the device and battery designer, a note was added to IEc 60086-1, clause 5, which specifically draws attention to the existence of both a protruding and a recessed negative contact. 4.3 Consumer information The consumer information contained in IEC 60086-1, clause 13, and published in this report provides clear and unambiguous advice which promotes the safe and proper use of batteries and also highlights the risks associated with abuse and/or misuse. 4.4Concentricity of the positive terminal In order to ensure that the position of the positive terminal facilitates polarization, concentricity limits were added to the dimensional specifications in IEC 60086-1, figures 1A and 1B. 4.5IEC 60086-5* - Product safety standard for primary batteries The IEC has already published a safety standard for lithium batteries and in the further pursuance of the needs for safety, technical committee 35 is currently preparing an international standard which incorporates all elements of safety pertinent to non-lithium primary batteries. * In preparation. 61955 @ IEC:1998 (E) - 6 - 5 Conclusion The attention of the user/reader of this technical report is drawn to the fact that the requirements of IEC/ISO Guide 51 and IEC Guide 104 were met with respect to design principles and duty to warn. Specific references in this regard are found in: Guide 51 Requirements for safety Testing and verification Information for safety Warning notices Marking Instructions for use Packaging Guide 104 Annex C - Principle elements of the safety objectives for electrical equipment AME 61955@IEC:1998 (E) - 7 - Annex A (informative) Consumer information leaflet The following consumer information is taken from IEC 60086-1, clause 13. A.1 Guidelines for handling primary/non-rechargeable batteries and the design of battery compartments A.1.1 User precautions for handling batteries a) Follow equipment instructions carefully and use the recommended batteries. b) Check the contacts of both equipment and batteries for cleanliness. If necessary, clean with EN a damp cloth and then dry. Insert batteries correctly with regard to polarity (+ and -). c) Do not allow children to replace batteries without adult supervision. Keep small batteries out of the reach of children. OM d) Never mix old and new, used and unused, or mix different battery types (for example different electrochemical systems, different grades or different brands). e) Do not attempt to revive used batteries by heating, charging or other means. Do not short-circuit batteries. f)[ g) Do not heat batteries or throw batteries into fire. h) Do not disassemble batteries. i) Be sure to switch off the equipment after use. NGALO j) Remove batteries from equipment if it is not to be used for an extended period of time k) Store batteries in a cool, dry place and out of direct sunlight. I) Do not defreeze batteries (household freezer). A.1.2 Design of equipment A.1.2.1 B
