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.
My one month review of the Fenix ALF-18 battery holder. I purchased this product to meet the $25 minimum requirement to qualify for free shipping. It’s made out of very thin ABS plastic, so it feels cheap and fragile. I would recommend storing it in the easy-open clamshell packaging that it comes in or something similar to prevent crushing. The copper-plated positive contact is securely molded in place and has a spring on the inside. I have personally tested both regular and protected button-topped 18650 Li-Ion rechargeable batteries with this product in my Fenix PD36R 21700 capable flashlight.
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.

Super handy for using 18650 batteries (especially the Cold-Resistant ARB-L18-2900L) in my 21700-type flashlights (PD40R V2.0 and PD36R)
