Valve-regulated Lead-acid Batteries for Moped - Part 1: Technical Conditions
1 Scope
This part of GB/T 22199 specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation, storage and operating requirements of valve-regulated lead-acid batteries for moped.
This part is applicable to valve-regulated lead-acid batteries (hereinafter referred to as batteries) and battery packs with a capacity of 28 Ah or less for electric automatic vehicles, electric scooters, electric balance vehicles, electric wheelchairs, etc., which use batteries as the main power source. The sulfuric acid electrolyte in the battery is non-liquid, adsorbed in the microporous structure between the electrodes or in the form of a colloid.
This part does not apply to lead-acid batteries and battery packs for other purposes such as starting, electric road vehicles and traction.
