    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, Murata, LG, Panasonic, Molicel, 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 physically and electrically protected battery pack. Never exceed the battery’s current rating and keep the plastic wrap and top insulating ring in perfect condition. Use of any of these batteries is AT YOUR OWN RISK.

    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 good performing cell that appears to use the same Yong De Li New Energy Company YDL 26650D cell that other companies also wrap. It appears identical to, and performs essentially the same as, the YDL cell.

    The capacity for the two Vapcells I tested was 4311mAh and 4433mAh at 860mA (0.2C) down to 2.5V. This is typically poor consistency for a China manufactured cell but these cells easily meet the 4200mAh minimum rating that YDL gives their cell. I am rating this cell at 4200mAh.

    Vapcell gives this cell a 32A “max continuous discharge” rating but that leads to a cell temperature a bit above my 80°C limit. I am giving this cell a 30A rating.

    Two cells were purchased for testing by me.

    Performance Specs
    • DC Internal Resistance = 15.9mOhms*** (milliohms) average for the two cells.
    • Watt-hours (energy) delivered at 10A down to 3.2V = 13.1Wh
    • Watt-hours (energy) delivered at 20A down to 3.2V = 10.3Wh
    • Watt-hours (energy) delivered at 30A down to 3.2V = 6.3Wh
    • 2-sec puff count at 30W = 786
    • 2-sec puff count at 60W = 309
    • 2-sec puff count at 90W = 126
    I want to work for the vaping community full time! If you feel what I do is worth a couple dollars a month and you would like early access to battery availability, battery and charger testing and news, and a say in what I test, then please consider becoming a patron and supporting my testing efforts: Battery Mooch is creating battery tests and educating vapers | Patreon.

    ***I have switched test jigs, resulting in slightly lower IR readings versus my previous setup. Add 1.6mOhms to this IR value in order to compare these cells to others tested previously.
