Fenix ARB-L16-1050UP Rechargeable Battery

The 1050mAh capacity handles my flashlight’s daily use without needing a top-up mid-week, which is a solid upgrade from my old cells. Charging straight through the Type-C port means I don’t have to dig out a separate charger, and it tops off in about an hour. Genuinely convenient for a spare battery

Charged it a few days ago and it’s still going strong in my 16340 light, the 1050mAh is enough for a solid evening walk. The Type-C port means I don’t need a separate charger on my desk, which is a nice win.

The integrated USB-C port is so convenient—I just plug it in like my phone and it's done. It's held up well in my daily carry light, and the 1050mAh capacity lasts a good while between charges. Exactly what I needed for a 16340.
