Have you seen this type of counterfeit 18650 battery before? UltraFire

A crack team of heavily armed Chinese mercenaries needs to be dispatched to eliminate all those connected in the manufacture of crapfire cells.

We would be lucky to bruise them if we send chinese mercenaries with chinese weapons & bullets. Can we pay for something better?

Testimonial from another forum about an 3200mAh Ultrafire cell:

"At 1 amp, i can only get 100 mah before hitting 3.0v from 4.2v.. at 2 amps. faghetaboutit.."

Cut an UltraFire cell, which claimed it was protected. Trying to find a protection board inside the cell is kind of absurd anyway.

After finding out about fake eggs - the mind boggles!
and my first set of Ultrafire 3600mAh 18650’s from eBay were fake they are in fact 950mAh :frowning:

Since then I no longer trust any claims and try to find trusted sources for my batteries.

Fake Eggs Youtube!

Meat glue. Think that steak is a real cut of beef? No more tasty med-rare. :_( Also lamb, chicken, pork.
Never got a fake egg.

"FirePeak" fake 3200mAh cells, tested to be 613mAh by the user.

There was a 18500 cell inside a 18650 shell.

Very interesting video, showing the powder. By the title you would think that the person believes someone faked the Ultrafire brand, at least I know some truly believe that sort of thing.

None the less you must see the video:

racist fake batteries?
filled with white power quote didnt work

My red ultrafire battery are holow, I left on charger for many hours unattended.

the sooner we educate the main consumers of these batteries the sooner the garbage will be gone from the market.
i often though of a few ebay buying accounts to buy these suspect batteries,test them,and neg/ding stars of the crap sellers.

Amazon members can leave reviews of this junk whether they have bought it from Amazon or not. Point out that the best lithium ion battery manufacturer in the world, Panasonic, can only produce 18650 batteries with a maximum capacity of 3200 to 3400 mAh. Anything with greater claimed capacity is a lie and the batteries are very probably complete junk.

I have an Ultrafire that shows 5.7 V on the multimeter. I guess that’s two 16340 in parallel right?

5.7v? Thats much too high. Its dangerous. Put it in a metal cash box (ends taped) or outside.
What charger did you have it in?

It would not be two 16340s together (in series).

Any one know anything about the Ultrafires being sold by Battery Junction? For most things they seem to be a major web seller and I know that they are a dealer member of CPF. The listed capacities sound reasonable so are these the genuine article, the mythical “genuine Ultrafire” batteries or more total junk?

Even 4.5V is dangerous for a 4.2V cell, especially if you start hitting the cell.

Yeah must be in series to get that voltage, but that would also mean there are 2 empty 16340, 5.7/2=2.85V

The lesson I learned is that its very hard to trust batteries with “fire’ in their brands. I have a good Marsfire 26650 (marked 5000 mAh but does 4321 mAh in my tests) which I bought from DX. All the other ‘fire’ cells that I have, however, are best thrown into the fire.

Never charged it, bought it locally with a cheap but fairly powerful “q5” flashlight. So i guess the led in that is overdriven to hell? I does warm up but nothing abnormal. Also throws like a champ since it’s a zoomie.

Dealer member of CPF means nothing. Just throw some money at CPF & you can be one too.
