  • Long Runtime With These Batteries

    - very cheap protected 18650's
    - built in protection circuits that actually work
    - high energy capacity (close to rated mAH rating)
    - good energy retention over time
    - tested runtimes with Ultrafire WF008 and with my Solarforce L2 R2 both set to high - more than 6 hours
    - fits my P60 hosts
    These are very good 18650's for the price. Energy storage capacities are close to the rated values. Overcharge and undervoltage protection circuits work. I have these Ultrafires as seconds for my Trustfire Protected 18650 3.7V True 2400mAh Rechargeable Lithium Batteries and am confident that they will work when needed and that their actual capacities are not that far behind from the Trustfires.
    I'm ordering more of these and am recommending them to friends.
  • Best Unprotected Battereies on DX

    Not quite 2600mAh, but pretty darn close to it
    Measured a consistant 2300 to 2400mAh on my meter which puts them in the elite class for 18650 batteries.
    Great price for this capacity.
    I would rate these batteries to be as good or better than the black and red Trustfires.
    They actualy have more capacity.
    Suprised that there is not more positive comments for this product.
    For the price you cannot go wrong.
    Protection for 18650's in my opinion is a waste of time, and most of the time it is of poor quality or does not work..
    Have used them for about 6 months with many charges.
    You would have to pay about 3 times the price for non DX batteries to get a 200 or more mAh, which is a waste of money.

    After few weeks waiting I got my batteries. It came in transparent plastic case which fits quite well the batteries. I am using it for 2 weeks during 10 minutes per day, charged once. It is working well so far.
    Good battery, last long and is very well built.
    Nothing else to say about it. Im stil testing it.
