[Source: GB 6675.1—2025, 3.1] 3.2 children‘s products Products designed or intended for use, play, wearing, etc., by children under 14 years of age. [Source: GB 46523—2025, 3.1] 3.3 juvenile products All products and materials designed or intended for use by children under 14 years of age. NOTE 1: Include, but are not limited to, student stationery, children‘s care products, children’s feeding utensils, children‘s textile products, children’s footwear, children‘s furniture, children’s protective gear, baby carriages and children‘s jewellery, and other products with specific functions to meet the various needs of children during their growth. NOTE 2: Exclude food, cosmetics and pharmaceuticals. [Source: GB/T 45276—2025, 3.2.1] 3.4 lithium ion cell A device that relies on the movement of lithium ions between the positive and negative electrodes to achieve the conversion between chemical energy and electrical energy, and is designed to be rechargeable. NOTE: The device includes electrodes, a separator, electrolyte, a container and terminals. 3.5 lithium ion battery A readytouse assembly composed of any number of lithium ion cells combined together, including a protection circuit. NOTE: A lithium ion battery may contain materials or components such as packaging materials, connectors and protective devices. 3.6 coin cell button cell coin battery A small, circular cell or battery whose overall height is less than its diameter. [Source: GB/T 28164.2—2015, 3.21] 3.7 user replaceable battery A battery used in a toy that allows the user to replace it without damaging the toy or the battery. [Source: GB/T 19865—2024, 3.6.8, modified] 3.8 user nonreplaceable battery A battery used in a toy that is not intended to be directly replaced by the user. [Source: GB 31241—2022, 3.6, modified] 3.9 nominal voltage An approximate value suitable for identifying the voltage of a cell or battery. NOTE: The nominal voltage of a battery shall match the nominal voltage of its constituent cells. The nominal voltage of a battery consisting of one or more cells connected in parallel is the same as the nominal voltage of the constituent cells. For a battery consisting of two or more cells connected in series, the nominal voltage is n times the nominal voltage of the cells (where n is the number of series connections of cells or parallelconnected groups of cells in the battery). [Source: GB 31241—2022, 3.7, modified] 3.10 rated capacity C The capacity of a cell or battery as declared by the manufacturer. NOTE: Expressed in amperehours (Ah) or milliamperehours (mAh).
