(5) Rated capacity

Refers to the discharge of the battery at a constant current of 0.5mA to a termination voltage of 2.75V before charging in an environment of 20 ± 5 ℃ and 65 ± 5% H; Leave for 15 minutes after standard charging; Discharge capacity at 0.2ItmA to 2.75V. Required discharge capacity: ≥ 100% C5mAh.

(6) Fast discharge capacity

Refers to the discharge of the battery at a constant current of 0.5ImA to a termination voltage of 2.75V before charging in an environment of 20 ± 5 ℃ and 65 ± 5% H; Leave for 15 minutes after standard charging; Discharge capacity at 0.2ImA to 2.75V. Required discharge capacity: ≥ 90% C5mAh

(7) Cycle life

Discharge the battery according to the standard discharge requirements and let it stand for 15 minutes. Under an environment of 20 ± 5 ℃ and 65 ± 5% RH, charge according to the fast charging requirements and let it stand for 15 minutes. Discharge at a current of 1500mA until the battery terminal voltage reaches the termination voltage of 2.75V. Cyclic charging and discharging, when the discharge capacity of any cycle is less than 80% CsmAh, the service life ends. The number of cycles is required to be greater than or equal to 300

(8) -20 ℃ discharge performance

The battery should be charged according to standard charging methods; The battery should be stored at an ambient temperature of -20 ℃± 2 ℃ for 16-24 hours; The battery should be discharged at a constant current of 0.2ImA at an ambient temperature of -20 ℃± 2 ℃ to a termination voltage of 2.75V; Discharge capacity ≥ 60% C5mAh
