This part of GB/T 19639 specifies the technical requirements, test methods, inspection rules, markings, packaging, transportation, and storage of general valve regulated lead-acid batteries (hereinafter referred to as batteries). This section is applicable to various DC power supply batteries with a rated capacity of less than 65Ah (including 65Ah) for emergency lighting equipment, uninterrupted power supply, mobile measurement equipment, etc. The single cell battery of this type of lead-acid battery can be either a flat electrode installed in a square groove or a coiled electrode installed in a cylinder. The sulfuric acid electrolyte in the battery is non flowing, or adsorbed in the microporous structure between the electrodes or in the form of a colloid. This section does not apply to batteries used for other purposes, such as starting lead-acid batteries, traction lead-acid batteries, fixed valve regulated lead-acid batteries, sealed lead-acid batteries for electric power assistance, and miniature valve regulated lead-acid batteries. 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.
