Bench Test Results: Juiced 20A 3000mAh 18650...accurately rated (sort of), seems identical to 30Q

    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
    These cells look the same and perform essentially the same as the 15A 3000mAh Samsung 30Q. Samsung rates the 30Q at 15A continuous but the datasheet mentions operation at 20A. Never let these cells exceed 75°C if running them at 15A-20A. The Samsung 30Q is a great performing battery though.

    The two cells I tested delivered 3108mAh and 3109mAh at 600mA down to 2.5V.

    I had some questions regarding Juiced saying their cells were specifically developed for vaping. I have asked Juiced about this and am waiting for their response.

    Juiced uses “IMNR HYBRID” on the wrap as, it seems, a battery chemistry designator but I have never seen that used before. The IMR and INR manufacturer model prefixes (they’re not chemistries) are common though. INR is already a prefix used for “hybrid” chemistry cells so using IMNR is a bit confusing in my opinion. But, each company is free to create any designator they want.

    The Juiced web site says that this cell uses a “Lithium-Manganese, Nickel” chemistry. The Samsung 30Q uses NCA chemistry though, nickel-cobalt-aluminum. If this is not a 30Q then perhaps it is NMC chemistry, nickel-manganese-cobalt? That is a common chemistry used by vapers. It looks and performs the same as a 30Q though.

    The Juiced web site mentions that they spent years researching and testing the best 18650’s, found this cell, and then improved it. I have requested info on what changes they have made. I have also requested the summaries of their previous testing as I am sure our community would love to know how different cells performed for Juiced. Any other test results we can get is great to have!

    I am ESTIMATING this Juiced cell’s ratings to be 15A continuous, 20A temperature-limited to 75°C, and 3000mAh.

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

    Performance Specs
    - DC Internal Resistance = 19.3mOhms (milliohms) average for the two cells.
    - Total energy delivered down to 3.2V at 10A continuous = 7.7Wh (Watt-hours) average.
    - Total energy delivered down to 3.2V at 20A continuous = 6.0Wh (Watt-hours) average.

    I want to work for the vaping community full time!
