The Fenix ARB-L18-3400 is a high capacity 18650 Li-ion rechargeable with a protection circuit in the anode to help prevent short circuits, over charge/discharge and over heating. The battery also includes pressure relief vents which expel waste gas in the rare case of an internal short circuit preventing an explosion.
Tuesday, December 17th is the last day to purchase and receive it by Christmas via free shipping.
5star Flashlight/Battery Life. Hearty/
Reliable. Bought mine after a 25
Year Use Of a customer at the sales
Counter who’s testimony told me Fenix is the best. I did buy Two and
So happy I did.
I needed a replacement battery for my TK20R and a rechargeable battery for my TK16. Now with the single port charger and 2 batteries I should never be without a good light.
The Fenix ARB=L18-3400 is a great battery. Be careful of counterfeits sold elsewhere for the same or less money. The counterfeits fail early. I will only buy these batteries from Fenix.
