    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 an accurately rated rewrap of the Molicel P26A, a great performing 25A 2600mAh cell. The klejjs cells look and perform the same as the P26A and get the same 25A rating. They are wrapped and marketed by N-Power Energy (NPE), the global distributors of Molicels to the vaping community.

    The capacities for the four cells I tested ranged from 2612mAh to 2633mAh at 520mA (0.2C) down to 2.5V. This is good consistency and I am rating these klejjs at 2600mAh.

    N-Power Energy donated four cells for testing, thank you!

    Performance Specs
    • DC Internal Resistance = 17.0mOhms*** (milliohms) average for the four cells.
    • Watt-hours (energy) delivered at 10A down to 3.2V = 7.4Wh
    • Watt-hours (energy) delivered at 20A down to 3.2V = 5.6Wh
    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.

    To see how other cells have tested check out this link: List of Battery Tests | E-Cigarette Forum

    ***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.
