10180 100mAh



Official specifications:

• Rated Voltage:3.7V (Limit 2.75v-4.2V)
• Capacity:100mah
• Cycle times: about 1000
• Size: 10*18mm

This is one of the smallest LiIon batteries used in flashlights. I got it from a Chinese dealer and there is no brand on the cells.








Capacity is not as high as rated and there is a capacity difference between the two tested cells. It looks like they can handle about 100mA, before capacity starts to drop.











Conclusion

This is not impressive performance of these batteries, but about what to expect for a cell with very low production numbers.
