    These tests below only note my personal ESTIMATED ratings for the batteries I tested 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 property damage, personal injury, or even death. They are not supposed to be used outside of a fully protected battery pack and you use them at your own risk. Never exceed the battery’s true continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.

    Testing batteries at their limits is dangerous and should never 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.

    Test Results
    This is a low cost cell that performs about the same as the Samsung 35E (not the 35E3) and EVE 29V. If you do not need the higher performance of the more expensive cells like the Molicel M35A and Samsung 35E3 then this cell could be a good choice for cost-sensitive applications.

    It has a 5.8A rating down to 2.75V (not 2.5V) and a max temperature spec of 60°C.

    I have not tested it but this cell has a very high cycle life spec in the data sheet, 1000 cycles before losing 20% of its capacity.

    The two cells I tested delivered 2923mAh and 2926mAh. This is fantastic consistency and is more like cells from the big manufacturers.

    Two cells were purchased for testing by me from Liion Wholesale (Liion Wholesale Batteries | Li-ion battery/cell distributor).
