This part of GB/T 5008 specifies the classification, technical requirements, test methods, inspection rules and markings, packaging, transportation, storage, and other contents of lead-acid starting batteries. This section is applicable to exhaust (rich liquid) lead-acid batteries (hereinafter referred to as batteries) and valve regulated (with gas recombination function) batteries with a rated voltage of 12V for starting, ignition, and lighting of various automobiles, tractors, and other internal combustion engines. This section does not apply to batteries used for other purposes, such as starting batteries for railway internal combustion engines. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document. GB/T 5008.2 Starting lead-acid batteries - Part 2: Product specifications and terminal dimensions, markings IEC 60095-1:2006 Starting lead-acid batteries - Part 1: General requirements and test methods - Terms and definitions, codes, classifications, 3.1 Terms and definitions - The following terms and definitions apply to this document. 3.1.1 Vented battery (flooded) A battery with one or more exhaust devices on the cover that can release gas products, including normal water loss batteries, low water loss batteries, and micro water loss batteries. 3.1.2 Valve regulated battery (gas recombination) is a sealed battery under normal conditions, but there is a device to release gas when the internal pressure exceeds a predetermined value. This type of battery cannot add water or electrolyte normally. In this type of battery, the electrolyte is not flowing. Maintenance of maintenance free batteries_ Free battery is a micro water loss type battery that does not require maintenance during its service life under specified conditions. 3.2 Code C. - Rated capacity at a rate of 20 hours, in ampere hours (A · h); C. - -- 20 hour rate actual capacity, in ampere hours (A · h)
