  • probably the best on DX

    posted by steinway

    - they are really protected. when the voltage gets low, it really cuts the power. using in my flashlight SKU: 121494. also, it doesn't charge more than 4.20V (I tested)- I have not tested the real capacity of them, but I believe that it really is 2400mAh- it lasts for more than one hour on my flashlight on HIGH
    i am really satisfied about the batteries. it takes a while to charge on SKU: 936
    probably one of the best you can find on DX.
  • The best 3000mAh 18650

    Excellent power output.Excellent burn time.Seem to be the claimed capacity.Look and feel the part.
    Run longer than any other battery I have tried.Give out more light than any other battery I have tried.Get a fast charger.
    They cost a bit more than other brands, but easily outperform the others, especially Ultrafire.Take about eight hours to charge when totally run down.
  • Great batteries

    Great build quality, been using the blue ones for ages and still working. Great deal for the price.
    If they were priced the same as the blue ones or the gray ones it would be great!
    Great overall value, highly recommended for any cheaper flashlights. But if you want to use them in more expensive flashlight, like over 100 dollars, think it over and for those buy rather some Panasonics, Nitecore or AWs

    Significantly better performance than my UltraFire 18650 protected 2600mAh batteries. Better looking too. Came in a nice translucent battery travel case, that was an unexpected treat!
    My TrustFire "Multifunctional Charger" (Model TR-001) goes into thermal shutdown when two of these charge at same time... this is actually a con against my two year old legacy charger, not the higher capacity batteries.
    I'm happy with this purchase. I have recommended to family and friends.

    Great price! Has "circuitry" built in to protect the battery. It works just fine with the charger I purchased http://www.dx.com/p/ac-charger-for-18650-battery-ac-100-240v-2-flat-pin-plug-125125 .
    This battery actually came in "packaging"; it came in a nice hang/blister pack.
    It seems to be a great battery. It holds a charge while stored. There are no negative issues at all. Powers
