At the 25th, 50th, and 75th charge and discharge cycles of the battery, discharge at a current of 512C until the average voltage of the single cell reaches 1.70V is terminated, and the capacity is calculated. Then the battery continues to be tested according to 5.16.2.2. According to the tests conducted in 5.16.2.2 and 5.16.2.3, when the battery capacity is less than 0.5C20 and it is verified that it does not increase after 25 charge and discharge cycles, the test is terminated. The number of charge and discharge cycles with a capacity less than 0.5C2 is not counted in the charge and discharge cycle life. The current-discharging life test
is greater than 41.
The entire test is carried out in an environment with a temperature of 40~45℃. After the battery is fully charged, it is charged at a constant voltage of 2.25~2.30V with an average voltage of the single cell. The maximum current shall not exceed 1.0V. The battery is discharged at a current of 512V every 2 months until the average voltage of the single cell reaches 1.70V, and the capacity is calculated. Then the battery continues to be tested according to 5.16.3.2. 5.16.3.4 When the battery capacity is less than 0.5Cac· and no longer increases after re-verification for 2 months, the test is terminated.

Sampling rules
JB/T6457.2-—1992
Type inspection can be carried out with a representative product of a certain specification. 6.3
Judgment rules
In type inspection, if one battery does not meet this standard, it is necessary to double the sampling test. If there is still one battery that does not meet this standard, it should be judged as unqualified.
