    Great price for TWO,
    18650 size 3.7v Lithium,
    UltraFire quality,
    Good actual mAh rating,
    Protected from under and over charging,
    One charge has lasted from the day I got them till now in a high brightness flashlight (FandyFire F102 Cree XM-L T6 600LM #128101)
    Great fit (even protected these do not seem "too long to fit" like others
    Come in a nice little storage case that fits two that keeps you from shorting out charged cells in storage.


    Rated mAh rarely reflects reality, although these are close. No other real cons


    Come on UltraFire, quit "stretching the truth" on your power ratings!! You are better than that.

    These are NOT AA or C cell replacements- your device has to accept this cell to work!!


    If you need some 18650s definitely get these!!
