  • Those are NOT Batteries, but Rechargeable Cells !

    posted by Dex-ter

    They are cheap. Also the effective time of working is good. I'm satisfied and'll buy them again :).
    Those are NOT Batteries but Rechargeable Cells ( see photos attached by me ). Inscriptions on the Cell are: "TR18650 2400mAh 3.7V" and "WARNING.The voltage of full charge and cut-off discharge is 4.2V and 2.75V. Don't heat, indicate or reverse polarity.".

  • good capacity

    posted by jernejtito

    It has good capacity 1,9 Ah at 0,7A at first test cycle. Normaly batteries in this price field only put out about 1,1 Ah.capacity 1,9 Ah at 0,7A at first test cycle.
    a little bit more in diameter 18,2 mm. nothing else to say.
    Good relations between price and stored energy. But only time will show the cycling life
  • 2600 mAh though rated "4000" = OK

    posted by hurupthy2010

    So far - Excellent performance doing appx 2600mAh compared to e.g TrustFire 2400mAh genuine rate.In other words: At this price - pt at a 20% bargain, I can only recommend this particular UltraFire, if You´re in need of new 18650´s......
    Why worry - if You buy and use some of these and perhaps some TrustFire 18650, 2400mAh, You will only become satisfied
    Buy - Buy - Buy. At this bargain, You will only become very satisfied........

  • Good batterys for a good price

    posted by Lightjunky

    The batteries do what they should do. The build quality seems to be ok, too. They have protection circuits, but still fit in my flashlight (FandyFire 5xCree XM-L T6 4000 lm) The cases in which the batteries are delivered are very helpful, if you take the batteries on a camping trip or something like that.
    I can not verify the battery capacity (2600mAh), but it seems to be ok.
    Good batterys for a good price. If you buy these, you do nothing wrong. :-)The delivery from DX was good. It is normal, that it takes about 2-6 weeks delivery time to gemany.
