Fenix ALF-18 18650 Battery Holder for 21700 Torches

The Fenix ALF-18 battery holder allows you to use a Fenix 18650 lithium-ion battery in a Fenix 21700 lithium-ion battery powered torch.

Made from PC and ABS plastics this adapter is the size of a 21700 battery and its internal bore fits the smaller 18650 battery. The adapter features copper plated contacts for excellent conductivity and fits both button top and flat top 18650 batteries thanks to the internal spring.

Simply insert the positive end of the 18650 battery into the bottom of the battery holder, and the holder with battery can be used in place of a 21700 battery in compatible Fenix torches.

Please note that as 18650 batteries have lower capacity than 21700 batteries run times in your application will be correspondingly shorter.

Compatible models included TK22 UE, PD40R V2.0, HT18 & HP25R V2.0
