  • Cheap 2400mah batteries

    posted by 13557 on 02:59:24 G8T 14/08/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Good high mah 18650 batteries that use Li-ion technology. These hold the charge well and last decades without deteriorating or losing voltage holdup. Cheap to buy a lot and good batteries.

    Cons: Nothing to say for improvements. Nice ones can't go wrong with them.

    Other: Super 18650 batteries looks like 2400mah and perform well on my flashlights and not at a bad price either good for many purposes if holders are bought.

    Pros: Price is lower than in Brazilian shops. They have a security system which prevents against the total ending of memory.

    Cons: Nothing at all. Its okokokokookokokokookokokokookokokokokokokokokokokokokokokokokokokokokokokokok

  • Nice battery with Protecting Circuit...

    posted by shaypc on 08:31:45 G7T 29/07/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Looks nice.
    Arrived already fully charged.

    Cons: Length is a little bit more than promised - could be a problem on some usages.
    I measured something around 6.8cm, where it is written to be 6.646 - about 15mm more.
    Guess it's because of the protection circuit - hope it will fit inside my Bosch Ixo ;-)

    Other: Nice price (although there are cheaper). Looks good quality.
    Buy if you need one...

    posted by GrAnd on 12:34:21 G3T 26/03/2009 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Has protection circuit board.
    The capacity is fair. Even more than advertised.

    Cons: The length... Since they have the protection boart then may not fit well some devices because they are longer than a holder.

    Other: Good batteries. The are absolutely worth the price.

    Involvement Level: Expert (understands the inner workings)

    Pros: - Fair price for protected cells
    - They are protected against over-discharge or charging explosion risks
    -Build quality is good
    -nice for flashlights ( if fits ;-) )

    Cons: - Looks a bit wider and higher than similar 18650 standard unprotected cells.
    - Capacity might not be as stated (2400 mAh)

    Other: - works great in my Aurora AK-P7-3 SSC P7 900-Lumen 2-Mode LED Flashlight
    - charging them using UltraFire 3.6/3.7V Battery Charger sku.1251

    posted by startkapital on 18:13:18 G10T 22/10/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Hello everyone!
    I just recently found about CREE Flashlights, so am not really a rookie just a beginner.
    I bought few models of DX and all modells are power either with CR123A or 18650 Lithium Batteries.
    My flashlight beam is as shiny and light as i wish. I was once a fan of Xeon lights like maglite and stuff... my pro gear now is a SSC lamp powered with one 18650 cell!
    maybe these protected cells could be usefull for remote controlled devices as well?

    Cons: I can really say cons here but here a few
    -not really 2400 mah
    I need to test them how many charge and discharge cyles these battiers hold... this may take a while

    Other: If you need 18650 cells buy there, u wont regret it!

  • Fits JetBeam Jet III Pro

    posted by waffle on 02:04:07 G10T 01/10/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: 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.

    Cons: None that I've noticed so far.

    Other: 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?

    posted by wayofthelight on 12:28:23 G8T 18/08/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: works great. Especially for drivers that support only up to 4.2 volts. runtime is very high with these cells. I do notice dimming so I dunno how well the protection works. I've gone through 7-10 charges on 1 cell and its still working great. Never ran a runtime test so i can't tell how long it'll run.

    Cons: 5 bucks each
    dunno how well the protection is. Other protected cells cut off... I see dimming with these.

    Other: I haven't had one fail on me yet. So my experience has been good. I would buy more if I lost the ones I have.

    posted by razako on 14:09:35 G5T 11/05/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: They are protected which is a good thing because you don't need to worry about them blowing up or over-discharging. They fit well in my ultrafire UV flashlight. I also have the trustfire 18650's and they get stuck in some flashlights. They are well built and both of them work as advertised.

    Cons: -Takes forever to charge the pair of them.
    -Actually capacity seems to less than 2400mAh.

    Other: Look no further if you need quality 18650's for a great price.
