    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    I've used it/them now for over a year. I use the flashligt at work occasionally. Others have flashlights with ordinary not rechargable batterys and end up changing them 3 in time for when mine comes to the point that it needs a recharge. Bought 3 batterys, ...
    Cons:
    None really that I can think of? Colour on the plastic??

    Great Item for Flashlight Conversion

    posted by ciphoenix on 12/06/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    These batteries are cheap enough that you can keep a few around in the charger waiting for use. This battery charges quickly.
    Cons:
    2400mAh is NOT the highest capacity for this type of battery, but the price is right.

    Great cells. Will buy more

    posted by awptickes on 04/08/2008 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Low-cost. They're 18650 cells. Other places sell these for over $10 each. Can also be used to re-cell laptop batteries. They last just as long as my name-brand cells. I use them in my Spyder II 300mW Green laser.
    Cons:
    After fully charged, some read at 4.2V, which is still within tolerance. The DX stock number sticker can be hard to peel off.
