This is a high current 16340 cell (i.e. cr123 sizes cell).

Conclusion

This battery has very good performance, but the current printed on the cell is rather optimistic.
As usual I will rate it as acceptable.



Notes and links

The batteries was supplied by AWT for a review.

That is a very descent battery, thanks for testing. If the availability and price will be as good as the Efest IMR or AW, I will get some for my small lights.
