　　Conduct over discharge to zero voltage test using STL18650 (1100mAh) lithium-iron power battery. Test conditions: Charge the 1100mAh STL18650 battery with a charging rate of 0.5C, and then discharge at a discharging rate of 1.0C until the battery voltage is 0C. Divide the 0V batteries into two groups: one group is stored for 7 days, and the other group is stored for 30 days; After the storage period expires, fully charge at 0.5C and discharge at 1.0C. Finally, compare the differences between the two zero voltage storage periods.

　　The result of the experiment is that after 7 days of zero voltage storage, the battery has no leakage, good performance, and a capacity of 100%; After 30 days of storage, there is no leakage, good performance, and a capacity of 98%; After 30 days of storage, the battery underwent three more charging and discharging cycles, and its capacity was restored to 100%.

　　This test indicates that even if the battery experiences over discharge (even up to 0V) and is stored for a certain period of time, the battery will not leak or be damaged. This is a characteristic that other types of lithium-ion batteries do not have.
