Fenix Flashlight

Use your rechargeable 18650 batteries in flashlights designed for 21700s with the Fenix ALF-18 Battery Adapter. The sleeve fits perfectly in 21700 battery compartments, giving you an option when a 21700 isn't available, but an 18650 is. Made of polycarbonate and ABS plastic, the sleeve features a copper-plated positive contact for optimal conductivity.
