  • Very good

    posted by speedy9

    - their capacity is probably close to the rated.
    - very low self discharge over time
    - protection circuit
    They are a bit longer then standard not protected cells so may not fit the devices where battery length is critical.
    I bought them to my flashlight (SKU 16179) and they are working great so far (around 11 months already). I use it on irregular basis but never found it not working even after a month staying in the drawer.
    It's a great deal! Do not buy other cells. They are just great!
  • Fits JetBeam Jet III Pro

    I was pleasantly surprised to find that this fit the Jet III Pro, which apparently has a reputation for only just fitting other cells. I went out of my way to order a certain premium brand of 18650s as well, but discovered that these ones fit anyway.
    Nothing to report.
    They're batteries, they're protected, and they do the job. You do tend to get what you pay for, though, so I won't be suprised if these don't last as long as the cells I paid more than twice as much for. Really, how far wrong could you go with these?
  • Good Batteries !!!

    posted by victorrolando

    I have other pair of the same batteries since 2011 that I use in a XML T6 torch and at full power, it drains 1 Amp at 3.6V, and run 1 hour. Build quality is good and fit in my torch, recommended to any who need a good 18650 battery at bargain price.It reach full charge at 4.2V and my torch dim when the battery voltage drop below 3.2V.It has pretection circuit to prevent overdischarge or overcharge.
    Comes in a plastic box inside que envelope, that is better than bubble plastic wrap.
    If you need a 18650 battery with good capacity, good price and good quality, don´t think more, buy it.
  • Great capacity, a bit big though

    The protection circuit works well. Gives peace of mind knowing you can't really over-discharge them.
    Batteries work great, have a nice capacity. Have already ordered more.. :)

    Excellent battery! Quite a large capacity, availability of protection.Fast charging, long operating time (with my flashlight) about 6 hours continuously!
    Overall I am very pleased with this purchase, the quality is very high, work long and recharged quickly! I recommend anyone who still doubts it is a great choice for super bright lamp or device with low power consumption
