Seems to be a solid performer
t's a Li-Ion battery, what more do you need to know??? It appears to charge/discharge as expected; there's no leakage; and they're very reasonably priced.

NOT 9900 mAh. This product is a scam. Typical Chinese lies and deceit.
Tested this cell, and it has a capacity of 2335 mAh. Charged it and discharged it 4 times on an Arduino dedicated cell tester. It is physically impossible to make an 18650 cell with more than 2800 mAh capacity. The chemistry inside has this limitation. Some Chinese vendors put flashy labels on these cells, overstating their capacity, some claiming 3000 mAh, some 4000 mAh, some 5000 mAh. If you are smart and you understand the chemistry you know this is impossible. But 9900 mAh ! I have never seen this level of shameless and brazen audacity. Amazon has become like Temu or Taobao. It is being abused by Chinese sellers. You cannot trust anything if it comes from China.
