What batteries work in the Fenix FD41 flashlight?Updated 2 years ago

The Fenix FD41 flashlight is compatible with one 18650 li-ion battery or two non-rechargeable CR123 lithium batteries.

Fenix Direct Charge batteries (with a charging port built in) can only charge under certain parameters,  We recommend using a single port charger that is around 2 Amps with no more than 10 watts max. Most multi port chargers will not work, this includes computer ports. This is due to interference with the safety circuit in the battery. Samsung and LG are great choices, Apple and Anker for the most part are not.
