    Default Test/review of GIF TR16340 2500mAh (Yellow)

    GIF TR16340 2500mAh (Yellow)



    Official specifications:
    • Model: 16340
    • Capacity: 2500mAh
    • Voltage: 3.7V
    • Chemistry: Li-ion
    • Color: Yellow, Red
    • Size: 32mm(Length) x 16mm(Dia.)




    A small battery rated at the same capacity as much larger batteries, this can only be a fake rating.










    The battery can deliver 300mAh as long as the load is below 1A, this is not very impressive. AT low load they are surprising well matched, probably because they are manufactured with this capacity.



    And it do not has enough energy to get really warm.















    Conclusion

    These cells may be cheap, but compare to what you get they are way to expensive. Any decent cell will have about double capacity and handle higher load much better.
    I will rate them as bad



    Notes and links

    How is the test done and how to read the charts
    How is a protected LiIon battery constructed
    More about button top and flat top batteries
    Comparison to other LiIon batteries
    My website with battery and charger information: lygte-info.
    More than 1000 reviews of batteries, charges and other stuff.
    Compare 18650 LiIon batteries or smaller (RCR123, 16340, 14500, 10450) LiIon batteries.

    Thanks HKJ.

    It seems that these cells that have ridiculously high claims are only matched by their ridiculously bad performance.

    To their credit, at least they have their own brand rather than claiming to be an AW cell or other.

    1) Help people that do not know that much about LiIon batteries.
    2) See if they use decent cells or bad cells.

    Open one of these and check what's inside. Doesn't surprise me if there is just a tiny cell inside.

    That is a possibility, but it is more likely it is a cheaply produced cell like this: http://lygte-info.dk/info/batteryDis...0mAh%20UK.html

    I will probably be opening some of the cheap cells, but not before the weather gets a bit warmer.

    I might open one of my chinese cells to.

    It has no name and only a crazy capacity of 140mah or lower. That's not good for a 18650 do you think ?


    The cell itself sounds hollow inside, so i guess there is a very tiny lithium cell inside.

    I will do a capacity test on it tonight and post a picture on here . It only runs a 12v bulb for atleast 15~30 seconds untill it dims.
    Proud to be dutch
