    These tests below only note the estimated ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, LG, Panasonic, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.

    Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. They are not meant to be used outside of a protected battery pack. Never exceed the battery’s current rating and keep the plastic wrap and top insulating ring in perfect condition.

    Testing batteries at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.

    If the battery has only one current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.

    Bottom Line
    This is a retest of the popular LG HG2, rated at 20A by the manufacturer. The four cells I tested, two from Liion Wholesale and two from Illumn, showed a bit less than expected consistency in performance but all tested as solid 20A cells.

    I have seen this cell with and without the laser-written “Caution” on the wrap. I don’t know if this is an option from LG or not but both types have tested as genuine. There are LOTS of fakes of this cell though. Only buy from known, trusted vendors. Check the pinned post on my Mooch Facebook page or my blog at ECF for my list of trusted vendors.

    There is also a version of the HG2 with the word “cigarette” misspelled as “cigaratte” in the Caution on the wrap. One theory is that this is an error by a China company that added the caution statement to genuine HG2’s for unknown reasons. This does NOT mean that all HG2’s with the “cigaratte” misspelling are genuine! Only that I haven’t seen any fake ones...yet.

    I am rating the LG HG2 at 20A and 3000mAh.

    Four cells were purchased for the purposes of testing by me.

    These cells have been rated by me before at 20A and 18A. Any rating in the tables can change at any time as different grade cells appear on the market or we get swamped with fakes. Please, never assume that the ratings in the table are permanent and will never change! Always download the latest version before considering any cell purchase.

    Performance Specs
    • DC Internal Resistance = 23.8 (milliohms) average for the four cells.
    • Total energy delivered down to 3.2V at 10A continuous = 7.52Wh (Watt-hours) average
    • Total energy delivered down to 3.2V at 15A continuous = 5.87Wh (Watt-hours) average
    • Total energy delivered down to 3.2V at 20A continuous = 4.93Wh (Watt-hours) average

    Looking forward to the video shootout between the HG2, 30Q, and VTC6.
