High accuracy, excellent workmanship.
Is also not too hot during charging (Quick Charger UltraFire WF-139).
After 1 month in use (5x previously charged) batteries have become even better.
I use this battery in my Fenix TK35 R5 (820 lumens) - once got the lighting time stopped: 2 days in use mostly in the high mode,
Overall, the battery has held more than 2h - Fenix is a luminous period in HIGH mode of 1.5h to.
Furthermore, this battery is also used for the EagleTac LED flashlight T20C2 Mark II from my son. He, too, has nothing but praise
Words for this product.
From me an absolute buy recommendation - especially pricewise 1A.
