    I consider Ultrafire cells an unnecessary risk and potentially dangerous, as well as being poor value for money. Cheaply made, often fraudulently advertised, is no bargain.
    they run lights as bright and as long as eagtac 18650 and charge fine and hold a charge

    I would never, ever order an ultrafire myself, I just happen to have a bunch from that mistake shipment
    a friend got and ended up with 50 new ultrafires. immediately charged and tested them for charge
    holding and they are fine. and guess what ? the labels on them are different than any ultrafire pictured here in this thread.
    so who knows which is the real slim shady ultrafire 18650 ? maybe mine are counterfeit ? they were packed nicely in sealed mylar

    anyway, they work great. would I buy them ? hell no !

    I consider Ultrafire cells an unnecessary risk and potentially dangerous
    ditto...I will carefully use what I have now and again, but they are going to be backups

    Question for anyone owning Ultrafire 18650
    -------------
    The ones I recently obtained:

    a) were individually wrapped in nickel mylar
    b) have blue labels
    c) the cathode cap is laser etched with the ultrafire logo and close scrutiny reveals it is very accurate


    Does anyone else have laser etched logo on the negative terminal of the Ultrafire 18650 ?
    The entire box of 50 have them.

    [this seems to be what a company would do to help sort out counterfeits.]

    The UltraFires I tested has logo on the bottom, but I do not believe that it is made with a laser.
    My website with flashlight, battery and charger information: lygte-info.
    More than 200 battery reviews and 80 charger reviews.
    Compare 18650 LiIon batteries or smaller (RCR123, 16340, 14500, 10450) LiIon batteries.

    lets put it this way...mine have etching that a laser could have done. how it was actually done I don't know.

    just wondering...I still won't buy ultrafires for myself, and don't really trust the ones I got for free. now after
    seeing the laser forums pictures of fake ultrafire....dang I might just throw mine out, laser-logo or not. for now I am
    keeping them in the skyrayking and will keep cracking it open and testing volts on all 4 cells and see what gives...

    Why would any company produce cheap, fraudulent knock-offs of lousy batteries anyway? It seems to me you'd want to label them with a good name brand if you were going to try and sell them dishonestly, not a questionable name.....

    Whats up with that?

    Fakes of name-brand batteries are way easier to distinguish from real ones, because real Panasonic's / Sanyo's etc even look high quality, you can tell it by feeling of shrink-wrap etc.. hard to describe, but hold a genuine NCR18650A in your hand and it'll have some kind of high-quality feeling to it.

    I just bought some ultra fire 18650's. Are these batteries dangerous? Could they explode or do damage to my flashlight? I have read in this threat that people say it's unsafe to use ultrafire's in a multi cell product. If poor quality a poor performance is all i have to worry about then i will just use them till they are toast and then buy AW's as it seems that people consistantly rate them high. Any input on my ultra fire's are much appreciated.

    Lithium batteries get damaged when the voltage drops below 2.7V. Never run them as long as you can like disposable alkaline. Recharge often long before they are depleted.

    I get these for the equivalent of $1 can't complain much about at that price. I have some AWs' as well but since the recent shipping ban (i am not in the US) i'll have to make do with these to feed my M6s. Compared to some salvaged laptop batteries and the AWs these are pretty light weight. Give me around 20 mins on high power on my M6LT before flickering. I'll let the pic speak for itself.

    That's a bad choice. Get unprotected cell from brand-name manufacturers, such as (alphabetical order, with no specific preference) LG, Panasonic, Samsung, Sanyo, Sony.
    They'll last you much longer (both in terms of cycle life, and per-cycle capacity), and they are also safer, because they have high quality control.

    Seeing that you need 4 of them, I'd recommend you following eBay lots:
    If you want maximum possible capacity: 221146637914 which'll give you 48 Watt-hours of power at $52
    If you want most capacity-per-dollar: either 180890419066 or 350585947314, both of which will give you approx. 35 Watt-hours of power at $22

    Thanks for the info, the charger i ordered says to use non-protected batterys or the charger will be damaged, it`s supposed to have it`s own protection built in, the two cheaper option one says it`s protected and the other the negative end looks protected even though it does not say so.

    This is the charger i ordered, ebay item 271073382603

    OMG that is the fakest of the fake battery I have ever seen !

    #1 logo incorrect
    #2 3800mah is currently impossible in 18650 format

    I bet if ripped open there is a tiny battery wired up inside

    You can use protected batteries in that charger with no problem, protection doesn't in any way interacts with anything except for the cell that it protects.

    I bought what I now know was a fake, red packaging with suposedly 3100mah capacity. It didn't have the 'Ultrafire' branding on the negative. It also said it was protected but simply had a carboard 'ring' where the protection circuit was!

    They were swiftly disposed of!

    Caveat emptor for cheap 18650 ebay purchases!

    Default First post - Ultrafire BRC18650 3000mAh - Are these fakes?

    Hi

    I received an LED bike light as a Christmas gift. It came with 4 Ultrafire BRC18650 cells (3000mAh)

    Everything about the package seems cheap. The battery holder is very flimsy with desperately poor soldering, and I'm seriously suspicious that the cells are not genuine.

    Two things about them:
    1. The red band at the bottom of the battery is much thinner than any I have seen on any Ultrafire BCR18650 on eBay

    2. The bottom plate of the battery is plain and silvery in colour, whereas everyone I see on eBay has a gold coloured base with Ultrafire written on it. (the picture in the advert showed YEZL batteries, but these were not supplied.)

    Appreciate your thoughts.

    Do you think they are fakes? The lettering includes the typical Ultrafire typo - 'sheef-life'

    Appreciate any comments

    Regards

    ksr

    Hi, for my point of view all the XXXXfire are not genuine, that because we cant know for sure what is inside, if you can replace all the batteries with real name batteries like, panasonic, sanyo, lg or sony.

    Sssh Re: First post - Ultrafire BRC18650 3000mAh - Are these fakes?

    I probably got robbed by DealExtreme. I bought a laser pointer, the SD-230 to be precise. Hardware-wise it's solid, sturdy and performs well. I use it for astronomy, which is my hobby. This is the URL to the laser I bought: http://dx.com/p/sd-230-aluminum-5mw-...x-18650-165185.

    It came with the blue UltraFire battery you see in the pictures, and this cheap fake charger. The light always stays green, even when a battery is not/wrongly placed. As for the battery, the bottom cap is silver, no laser etchings, the top is surrounded with some sort of cardboard ring.

    I've obviously been scammed battery-wise, as charging the battery for several hours does not do squat. The laser dies down just as fast. I'm a real noob when it comes down to batteries and testing them, so I would appreciate if anyone of you could help me in finding good quality 18650 batteries, which will last long enough and provide enough power so I can keep on using this laser. I'm not that rich as I'm still a student, lol. So if the shipping cost to Europe could be limited, I'd be very grateful.

    -Thanks

    Did a quick check on the UltraFire 18650's 3000mAh batteries i bought off eBay from a local seller here in Australia.

    Poor results, i also tested some 18650 2200mAh ones that i got with a torch i bought from a electronics company called Jaycar.

    Results.

    UltraFire 3000mAh
    Test #1 - 812mAh's
    Test #2 - 745mAh's

    Jaycar 2200mAh
    Test #1 - 2215mAh
    Test #2 - 2217mAh

    Tested on a battery tester with a discharge rate of 400mA. Each battery tested down to 2V.

    Also weighed the batteries.
    UltraFire 3000mAh - 33 grams

    Jaycar 2200mAh - 47 grams

    Cheers

    Hi Simon

    Probably a bit late now but DON'T discharge them down to 2V. Most low voltage protection circuits kick in at just under 3V for a very good reason.
    Even the newer Panasonics are only rated for 2.5V maximum discharge.

    You are seriously risking the health of both your batteries and yourself with this level of discharge.

    From your number of posts and recent join date, I'm assuming you are new to this type of chemistry.
    I suggest you do some reading on the subject of Li-Ion cells. There are any number of useful threads here at CPF. Keep in mind that the low voltage you have taken them to will be even more dangerous if you left them in that discharged state for any length of time.

    I'm not sure of the quality of the Jaycar products, but if you are looking for a reputable Australian seller, contact Yass - (ebay seller Supersports600). He can steer you towards more suitable cells including the latest Panasonics. His mobile number is listed on his ebay page if you wan't to ask questions.

    Cheers

    I just purchased some of the fakes off Ebay myself. I'm waiting for a reply from the seller. Glad I have other batteries on the way as back ups!
    These things won't even run an e-cigarette for 3 hours let alone the expected 17 or so hours.
    Mine have the fake logo and LC on the label not the AX.
    Can supply a pic if anyone wants one.

    I've not had good luck with any of the ****Fire batteries. I prefer AW, Readilast, Panasonic, and Callie's Kustom 18650 batteries. They cost only a little more and will last a lot longer--so in the long run these brands provided me with good value (as well as a modicum of safety). Spend enough time on CPF and you'll notice that people who have peeled labels off find all kinds of odd batteries under the familiar label.
