Record the terminal voltage, electrolyte density and temperature of the battery before and at the beginning of discharge. Record once every 50 hours for 500-hour rate discharge and once every 1 hour for 10-hour rate discharge. When approaching the termination voltage, measurement must be made at any time. Stop discharging when the battery voltage reaches 1.80V, and record the discharge duration, electrolyte temperature and density. During the capacity test, the electrolyte temperature is in the range of 15~40℃.

5.7.1 The battery under test must be tested and meet the requirements of 4.2 to 4.6. (2)
5.7.2 The battery shall be discharged at a 10-hour rate in accordance with 5.4. Each time the 10-hour rate discharge is completed, it is considered a life cycle. When the 10-hour rate discharge capacity is less than 80% of the rated value, another verification test may be conducted. If it still fails to reach the rated value, the life cycle is terminated. The cycle in which the discharge capacity is less than 80% of the rated value is not counted in the life cycle number. Its life cycle shall comply with 4.7. 5.8 The battery performance test sequence shall be carried out according to Table 3. Performance test sequence table
