    Default Test/Review of LG 18650 C2 2800mAh (Orange)

    LG 18650 C2 2800mAh (Orange)



    I could not find any specifications on this cell.



    This battery can be charged up to 4.3 volt.







    The batteries has a high voltage, even at high loads. The capacity is below the specified capacity.











    These are unprotected cells.



    Most LiIon chargers can only charge to 4.2 volt, a possibility to get 4.3 volt is a hobby charger with adjustable charge voltage (Like iCharger).



    LG 18650 C2 2800mAh (Orange) at 4.2 volt



    Reducing the charger voltage to 4.2 volt reduces the capacity with about 200 mAh.

















    Conclusion

    LG does make very good cells and the higher output voltage when loaded can be interesting for some applications. But it requires a special charger.



    Notes and links

    I have only added the 4.3 volt test to the bar charts, but both 4.2 and 4.3 volt can be found in the 18650 comparator, this makes it possible to compare voltage at different loads and charge conditions.

    The batteries was supplied by cpf user "Candle Lamp" for review.

    Great work. Thanks a lot for your time & efforts as always. HKJ!

    It seems 2800 is not so good compared to 3000mAh.

    I appreciate your great work.

    They are rated at 200mAh less capacity and they have about 250mAh less capacity, it is not that big a difference. They do have the higher voltage, compare to other LiIon batteries.
    But if I had to select what batteries to use with a 4.3 volt charger, I would select the 3000mAh batteries.

    All the 4.3v batteries I know of are 2800's. 3000's are all 4.35v.

    I did not express my self clearly enough, I would prefer a 4.35 volt 3000mAh at 4.3 volt, it has slightly more capacity.

    Here is a curve from my comparator:

    Hi HKJ,

    I have some of these cells and an OPUS BT-C100. Should I charge them at 3,7 or 3,8V?

    Thanks,
    Lucian

    They are 4.3V cells, this means somewhere in between.
    If you want maximum capacity from them use 3.8V (They will be slightly overcharged).
    If you want maximum lifetime from them use 3.7V

    Hello again,

    Thanks you for the answer. I went into details due to the fact that these type of 4.3/4.35V cells are rising questions from users like me (beginners). I have also some D1 and I stick to them at 3.8V charging. The idea is to use them with Opus BT-C100 as a power bank, if no issues.

    I appreciate your work,
    Lucian
