    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.
