The ALF-18 battery holder allows you to use an 18650 battery in flashlights that are built to use a 21700 battery. Simply insert your 18650 battery into the holder and place both into your 21700 capable flashlight. Made with copper plated contact, providing excellent conductivity performance. Compatible with button top as well as flat top 18650 batteries.
This battery holder also comes with the Fenix HT18 flashlight. It works perfectly anytime I need to use an 18650 battery in place of a 21700. Fenix used super high-quality materials in this battery holder. You can toss it in a hunting bag or emergency kit bag and not worry about it losing its shape. It’s built tough. At this price, I’m going to pick up a couple to toss in multiple bags and in our cars as back-ups.
