This European Standard is applicable to lead-acid batteries with a nominal voltage of 12 V, used primarily as power source for the starting of internal combustion engines (ICE), lighting and also for auxiliary equipment of ICE vehicles. These batteries are commonly called “starter batteries”. Batteries with a nominal voltage of 6 V are also included in the scope of this standard. All referenced voltages need to be divided by two for 6 V batteries. The batteries under scope of this standard are used for micro-cycle applications in vehicles which can also be called Start-Stop (or Stop-Start, idling-stop system, micro-hybrid or idle-stop-and-go) applications. In cars with this special capability, the internal combustion engine is switched off during a complete vehicle stop, during idling with low speed or during idling without the need of supporting the vehicle movement by the internal combustion engine. During the phases in which the engine is switched off, most of the electric and electronic components of the car need to be supplied by the battery without support of the alternator. In addition, in most cases an additional regenerative braking (recuperation or regeneration of braking energy) function is installed. The batteries under these applications are stressed in a completely different way compared to classical starter batteries. Aside of these additional properties, those batteries need to crank the ICE and support the lighting and also auxiliary functions in a standard operating mode with support of the alternator when the internal combustion engine is switched on. All batteries under this scope need to fulfil basic functions, which are tested under application of EN 50342-1:2015.

This part of IEC 60095 is applicable to lead-acid batteries used for starting, lighting and ignition of heavy trucks, commercial vehicles, busses and agricultural trucks. This second edition cancels and replaces the first edition published in 1989 and its Amendment 1 (1996). It constitutes a technical revision.

This European Standard is applicable to lead-acid batteries used for starting, lighting and ignition of passenger automobiles and light commercial vehicles with a nominal voltage of 36 V. This standard specifies the position, details of design and dimensions of a system of battery terminals. Starter batteries with 36 V nominal voltage may have the same dimensions and means for fixation as 6 V or 12 V batteries. This can be either intentional or unintentional. Therefore, the compatibility of batteries with 36 V nominal voltage down to electric power nets with 6 V or 12 V nominal voltage should be prevented. Such design of a 36 V termination and contacting system must prevent the case to be connected to a 6 V or 12 V power net in order to avoid serious damage in the 6 V or 12 V power net. For the same reason the design of the battery terminals must prevent that standard commercial jumper-cables may be contacted to the 36 V battery terminals if the battery is installed in the vehicle or not. A commercial application of this standard must expressively be agreed upon as the final standard may differ from the present draft.

This part of IEC 60254 is applicable to lead-acid traction batteries used as power sources for electric propulsion. The object of the present standard is to specify: - the maximum external (overall) dimensions of traction battery cells, that is, the width, the height and the length; - the form of the marking of traction battery cell polarity and dimensions of corresponding symbols; - the basic dimensions of some commonly used traction battery terminals designed to connect output cables to the battery; - the dimensions of cells commonly used in Asia and North America. This fourth edition cancels and replaces the third edition published in 1997 and its Amendment 1 (2000). It constitutes a technical revision. The main modification concerns the introduction of new dimensions.

This European Standard is applicable to lead-acid batteries used for starting, lighting and ignition of passenger automobiles and light commercial vehicles with a nominal voltage of 12 V. All batteries in accordance with this European Standard can be fastened to the vehicle either by means of the ledges around the case or by means of a hold-down device engaging with the lid.

This document is applicable to lead-acid batteries used for heavy vehicles. The object of this document is to specify the European requirements of the main dimensions of starter batteries. For new and future developments of the above applications, it is expected that only batteries from the “Preferred Types” series be used. Batteries of the series of “Other Types” exist under several national standards. They have been transferred from the previous standard EN 60095 4. The preferred types A, B and C are newly introduced and correspond closely to the types D4, D5 and D6 with some differences in tolerances and dimensions.

IEC 63056:2020 specifies requirements and tests for the product safety of secondary lithium cells and batteries used in electrical energy storage systems (Figure 2) with a maximum DC voltage of 1 500 V (nominal). Basic safety requirements for the secondary lithium cells and batteries used in industrial applications are included in IEC 62619. This document provides additional or specific requirements for electrical energy storage systems. Since this document covers batteries for various electrical energy storage systems, it includes those requirements which are common and minimum to the electrical energy storage systems. Examples of appliances that are within the scope of this document are: • telecommunications, • central emergency lighting and alarm systems, • stationary engine starting, • photovoltaic systems, • home (residential) energy storage systems (HESS), and • large energy storage: on-grid/off-grid. This document applies to cells and batteries for uninterruptible power supplies (UPS). This document does not apply to portable systems 500 Wh or below, which are covered by IEC 61960-3.
