The definition of some terms in this standard is Battery - (1) single cell or (2) series/parallel connection of a group of cells. Battery, Secondary - A battery that can be discharged and charged many times. 3.4Cel1- A single electrochemical cell containing both positive and negative electrodes. Component, current limit refers to the current limiting measures adopted by any component under abnormal conditions, including resistors, fuses, or thermal cut-off components that limit the current. Component, Temperature-LIMITING - Under abnormal conditions, any component must be subject to temperature limitations, including temperature protectors and temperature fuses. Discharged, Forced: The battery is forcibly discharged in series with an external power source, with the aim of ultimately achieving a reverse polarity state. Discharged, Fully When a 100 resistor is connected and the short-circuit current decreases to less than 1mA, the dead cycle circuit voltage of the battery is below 0.2V, which means the battery is completely discharged. 3.15 Material, Toxic - A toxic industrial product designated in the SAX Industrial Material Hazardous Performance Reference Manual. EXPLOSION - When the cell or battery part is forcibly opened and the cell or battery casing is damaged or split in half, or when the electrolyte of the battery or cell leaks in liquid, droplet, or vapor from the designed valve or sealing mechanism. 3.12 ACTIVE DEvices - such as FUSE, diodes, and current limiters, can prevent leakage current and limit the discharge current in a single flow direction in the circuit. RATED CAPACITY - The capacity measured by connecting a cell or battery to a circuit with a load, temperature fuse, and power fuse specified by the manufacturer, in units of AMH.C5 AMP RATE - to discharge a cell or battery for 5 hours, When the voltage drops to the manufacturer's nominal cut-off point, measure SHORT CIRCUIT - Short circuit the positive and negative poles of the cell or battery in a path close to zero resistance for discharge
Function of testing report:
