Test/review of 10180 100mAh

[size=+3]10180 100mAh[/size]



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.











[size=+3]Conclusion[/size]

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

How is the test done and how to read the charts

I had a small light and it came with this battery. I realize that capacity is low. I could not get it to charge past 4.0V.The battery was drained with in a few minutes.

I returned the light and said goodbye to any 10180 battery for future use!

Judging by the multiple manufacturers that design lights that use these, they must be reasonably popular; McArmy, Wuben, Fenix, Ultratac, Klarus, etc. I always wonder though, what those built-in chargers are doing to those batteries. The only external charger I have (that I trust to charge these properly) is the SkyRC MC3000 (using a spacer), where I can set charging current to 50ma.
