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.
Works great. Allows me to run my 18650 batteries in a 21700 flashlight! If my flashlight dies at a bad time, I have the ability to scavenge a 18650 from some other device I carry to get the flashlight up and running.

Another Fenix winner. This is a professional tool in a compact form. Tons of light and other features. I am a committee member for our local FIREWISE prevention efforts. This flashlight will be given away as a door prize at our upcoming event. The pitch is to have the PD40R V2, charger, and spare battery in your Bug Out kit.
