Foreword
GB/T 5008 “Lead-acid starter batteries” is divided into two parts.
- Part 1. Technical conditions and methods of test;
- Part 2. Dimensions of batteries and dimensions and marking of terminals. This Part is Part 1 of GB/T 5008. This Part is drafted in accordance with the rules given in GB/T 1.1-2009. This Part replaces GB/T 5008.1-2005 “Lead-acid starter batteries - Technical
conditions”. As compared with GB/T 5008.1-2005, it mainly changes in the following.
-The standard’s name is changed to “Lead-acid starter batteries -Part 1. Technical conditions and methods of test” (SEE the cover; the cover of the 2005 version);
ADD “classification” and content (SEE Chapter 3; Chapter 3 of the 2005 version);
ADD technical requirements for “battery model, dimensions, classification, terminal dimensions, and polarity” (SEE 4.1);
ADD technical requirements for “electrolyte density and open-circuit voltage” (SEE 4.2);
MODIFY the technical requirements for “20 h rate capacity” (SEE 4.3.1;
4.1.2 of the 2005 version);
MODIFY the technical requirements for “-18 °C low temperature startup performance” (SEE 4.4.1; 4.2 of the 2005 version);
- ADD technical requirements for “-29 °C low temperature startup performance” (SEE 4.4.2);
-MODIFY the technical requirements for “charge acceptance” (SEE 4.5; 4.3 of the 2005 version);
- MODIFY the technical requirements for “charge retention” (SEE 4.6; 4.4 of the 2005 version);
-ADD and MODIFY the technical requirements for “cyclic endurance” (SEE 4.8; 4.6 of the 2005 version);
Lead-acid starter batteries –
Part 1. Technical conditions and methods of test
1 Scope
This Part of GB/T 5008 specifies the classification, technical requirements, test methods, inspection rules and signs, packaging, transportation, storage and other aspects of lead-acid starter-batteries.
This Part is applicable to the vented (flooded) lead-acid battery (hereafter known as battery for short) and valve regulated (gas recombination) battery with a nominal voltage of 12 V, which are used for the starting, ignition, and lighting of various automobiles, tractors, and internal combustion engines.
This Part does not apply to batteries used for other purposes, such as. railway internal combustion engine starter-batteries.
