How do the valve-controlled battery packs do capacity testing?

The valve-regulated lead-acid battery pack is charged and discharged at a constant current, with both the charging and discharging currents set to I10. For a 2V battery, the discharge cut-off voltage is 1.8V; for a 6V battery, it is 5.25V; and for a 12V battery, it is 10.5V. Once any individual battery reaches its cut-off voltage during discharge, the process should be immediately stopped. During three complete charge-discharge cycles, if the measured capacity falls below 100% of the rated value, the battery pack is considered不合格 (unqualified). It's important to ensure that all batteries are in good condition and meet the required performance standards to maintain the reliability and efficiency of the entire system.
