    Default 18700 Battery & Flashlights Compatibility Data

    hi all!
    How would you feel on making such a chart/database?
    A list of flashlights that will accept the new longer 18650s, harboring at the 69+mm length.

    (I admit I have a self-interest because on another thread I am asking about a particular flashlight)
    But I guess others will benefit too.

    So....
    if your flashlight accepts the likes of XTAR, Intl-Outdoor. keeppower and orbtronic chime in!


    EDIT: here is the list so far....

    Am interested, but haven't those batteries you name. My longest 18650 is from a unbranded Panasonic 18650 3100mAh -length; 69,5mm

    I have a KLARUS RS11 on the way, any idea if the 18700's will work with that?

    Would the longer length pose any problems for the spring in the lights assuming it fits? Wouldn't it be too compressed over time such that going back to running a normal 18650 would create contact issues? Other than that I am interested.

    Compressing and uncompressing a spring is what wears them out. Theoretically, keeping a spring under constant, consistent pressure should have no negative effect.

    The Xeno G42 XM-L U2 has no problems accepting the longer and wider cells.

    Xtar 18700 works fine in Shiningbeam S-mini.
    It's too long for a Tiablo A9. (Well, it sort of works, but you have to screw it down at the tail for contact, and leave it a little loose at the head.)

    The MG S-mini by Shinning Beam newer version with shorter spring at the head works fine. The older version with a longer spring does not work well with the longer cell.

    Fenix TK15(now the old 332 Lum model) will NOT work with Callies 3100 m/amp batteries. Mine measure 69.7mm

    These long batteries just fit in a TK35

    XTAR 18700 2600mAh

    dont fit in all samples of Eagletac T20C2 MkII XM-L U2 because the pin of the tailcap (it's not a bare spring but a gold/brass/silver/aluminum pin!) can be pressed fully down OR NOT. if the tailcap is a perfect assembly of parts (spring, pin, ..), then the pin can be pressed all the way down, and 18700 will fit. otherwise the pin can be depressed only 70% ("bad tailcap") and the tailcap wouldnt close with 18700's. so generally speaking, 18700 fit in the T20C2 MkII, and if there is the pin problem with the tailcap, one has to ask the dealer for ..etc..

    So it looks like other than the Fenix TK35, so far, the other Fenix lights do not accet these. Too bad because Fenix is all I have.

    Hopefully we will have early test results if the 18700 fits the TK75.

    Anyone knows whether the Keeppower 3400mAh will fit into Zebralight SC600?
    I'm not too worried about the length. I'm more concern about the diameter though. Appreciate any feedback.
