Lead-Acid Starter Batteries

Gives guidance on procedures for testing the effectiveness of devices which are used to reduce the hazards of an explosion, together with the protective measures to be taken.

IEC 60095-7:2019 is applicable to lead-acid batteries used primarily as a power source for the starting of internal combustion engines, lighting and ignition (SLI) of motorcycles and other power sport vehicles. The nominal voltage is 12 V or 6 V. Test definitions and criteria in this document are for batteries with a nominal voltage of 12 V only. For batteries with a nominal voltage of 6 V, all voltages have to be divided by two. The other power sports vehicles covered in this document are snowmobiles, personal water crafts and all-terrain vehicles. This document is not applicable to batteries for other purposes, such as the back-up power sources, auxiliary equipment of internal combustion engine vehicles and e-bikes. This document specifies: • general requirements; • size, essential functional characteristics, relevant test methods and results required.

IEC 60095-6:2019 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". The batteries within the scope of this document 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 where there is no need to support 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 are 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 from these additional properties, these batteries need to crank the ICE and support the lighting and also auxiliary functions in a standard operating mode with the support of the alternator when the internal combustion engine is switched on. All batteries within this scope fulfil basic functions, which are tested under the application of IEC 60095-1. This document specifies the general requirements and methods of test specific to lead-acid batteries used for micro-cycle applications. This document is applicable to batteries for the following purposes: • lead-acid batteries of the dimensions according to IEC 60095­2 for vehicles with the capability to automatically switch off the ICE during vehicle operation either in standstill or when moving ("start-stop"); • lead-acid batteries of the dimensions according to IEC 60095­2 for vehicles with start­stop applications with the capability to recover braking energy or energy from other sources. Li-ion technology is excluded from this document.

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. The main technical changes in this new edition relate to the reduction of the number of European battery types, the standardization of dimensions and locations of battery terminals and the updating and inclusion in the standard of Amendment 1(1996), related to North America & East Asian battery types.

IEC 60095-2:2009 is applicable to lead-acid batteries used for starting, lighting and ignition of passenger cars and light vehicles with a nominal voltage of 12 V. All batteries in accordance with this standard can be fastened to the vehicle either by means of the ledges around the container or by means of a hold-down device engaging with the lid. This standard covers battery sizes of the geographical regions Europe, East Asia and North America.
