  • Great for laptopcell replacement!

    posted by bernardo

    Im just writing another review cause I just found out this cells are great for laptops! I just replaced my 4 cell acer laptop battery with 6 of this and now my laptop battery lasts for 3 hours! Much cheaper that a new battery :)
    Also very nice for flashlights!
    Get them, whether for using with flashlights or laptop cells replacement. These are great batteries.
  • Great battery life

    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.

    Nice battery, if it fits your flash light. Fair price.
    These battery's are ok as long as your not planning on using them in a Ultrafire WF-501b flashlight. for this flashlight SKU: 20392 Trustfire battery's are a better choice.
    Good battery if it fits your flashlight.
  • Very good

    Very long lasting. They fit my flashlights very well. Protection card at bottom of cell works very well keeps from over charging and low voltage from ruining the cell. Great product well constructed.
    Seems to last as long as the sku 20392 red and black batterys at about $1.25 USD per cell less cost.I have had no problems with any of them so far. Color is a bit drab (grey)but who sees them inside the light anyway. I have used in both of my flashlights for more than one hour on high beam.
    I bought them to my flashlight (SKU 16179) and they are working great so far (around 1 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!
