Fenix ARB-L16-950P Rechargeable Battery

The 950mAh rating is spot on—it's lasted noticeably longer than my old 16340s in the same flashlight. The protection circuit at the anode gives me peace of mind when charging it overnight.

Honestly the 950mAh capacity is the reason I grabbed this over my old 16340, and it does seem to last noticeably longer in my flashlight. The protection circuit on the anode gives me peace of mind when I toss it in my pocket charger.

I've cycled this little 16340 about thirty times now and the 950mAh has held steady each charge, which is exactly what I hoped for. The integrated protection circuit in the anode gives me peace of mind when I toss it in my pocket with keys.
