Fenix ARB-L18-1100 Rechargeable Battery

I've been running this 18350 in my EDC light for two weeks and the 1100mAh capacity holds up noticeably longer than the older cells I had. The 7A output rating means it powers my high-drain light without any sag, even when I'm using it at full blast.

The 1100mAh capacity easily got me through a full evening of flashlight use, and the 7A output kept my light running at full power without any stutter. It charges up fast too, so I've stopped worrying about swapping batteries mid-task.

Took it on a week-long camping trip and the 1100mAh capacity outlasted my old cell by a good two days of heavy flashlight use. The 7A max output keeps my light bright even when it's half drained.
