IEC 60095-1:2018 pdf download.Lead-acid starter batteries – Part 1: General requirements and methods of test
1 Scope
This part of IEC 60095 is applicable to lead-acid batteries with a nominal voltage of 1 2 V, used primarily as a power source for the starting of internal combustion engines, lighting, and for auxiliary equipment of internal combustion engine vehicles. These batteries are commonly called “starter batteries”. This document is applicable to batteries for the following purposes: • batteries for passenger cars; • batteries for commercial and industrial vehicles. This document is not applicable to batteries for other purposes, such as the starting of railcar internal combustion engines or for motorcycles and other power sport vehicles. This document defines many general properties of lead-acid batteries. Single sections can be referenced in other parts of the IEC 60095 series even if the application is excluded in the scope of this document. This document specifies the: • general requirements; • essential functional characteristics, relevant test methods and results required, for several classes of starter batteries: • according to the general type of application; • according to the type of product.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60050-482 and the following apply.3.1 flooded battery lead-acid battery having a cover provided with one or more openings through which gaseous products may escape 3.2 enhanced flooded battery EFB battery flooded lead-acid battery with additional special design features to significantly improve the cycling capability compared to standard flooded batteries 3.3 valve regulated lead-acid battery VRLA battery lead-acid battery which is closed under normal conditions but which has an arrangement that allows the escape of gas if the internal pressure exceeds a predetermined value Note 1 to entry: The VRLA battery cannot receive addition to the electrolyte and after activation of dry-charged VRLA. Note 2 to entry: In VRLA batteries the electrolyte is immobilized. 3.4 absorbent glass mat battery AGM battery VRLA battery in which the electrolyte is immobilized by absorption in a glass mat 3.5 gel battery VRLA battery in which the electrolyte is immobilized by fixing as a gel
4.3 Electrolyte density and open circuit voltage The density of the electrolyte in all fully charged vented batteries shall be in the range of 1 ,27 kg/l to 1 ,30 kg/l at 25 °C unless otherwise specified by the manufacturer. NOTE For valve-regulated batteries, the electrolyte is not accessible and, therefore, its density cannot be checked. The open circuit voltage (OCV) at 25 °C, of fully charged batteries after a minimum 24 h stand on open circuit, shall be in the range of 1 2,70 V to 1 2,90 V for vented types and 1 2,80 V to 1 3,1 0 V for valve regulated types unless otherwise specified by the manufacturer. The manufacturer shall specify the value and tolerance of the electrolyte density or OCV. If such information is not available, vented battery testing shall be carried out with a density of 1 ,28 kg/l ± 0,01 kg/l at 25 °C or an OCV of 1 2,76 V ± 0,06 V at 25 °C and valve regulated battery testing shall be carried out with a minimum OCV of 1 2,80 V.
