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

I’ve linked this on a load of vaping sites today.

We have all known for a long long time to stay away from the brc3000 ultrafire cells, vapers are no where near as savvy.

The response has been overwhelmingly positive, which was the hope, we really baby our cells compared to some vapers so I’d rather people were aware.

Thanks a lot gords1001 :wink: , that’s about all we can do to help. I suppose the market for these type cells is greater in the vaping market than anywhere else. If we could all pitch in I’am sure we could make a dent in the numbers sold.

Yeah thanks gords1001. And moderator007 yeah that is all we can do.

The rather weird part is you can s ee those German sellers sell a lot of them. To most of the emerging markets and even developed countries the fact that a German seller offers those cells means everything is correct and tested, but that is just and old cliche. That is also why some of those companies even try to use German sounding names like Heider to sell ultra cheap flashlights. So what I am trying to say that US and German sellers selling thousands of these cells is actually a guarantee for many people to buy from local sellers anywhere in the world UltraFire cells.

I have cut open a few. As above but bring battery down to 0 volts as you are going to destroy it, no? To cut into a charged or partially charged cell could get interesting.

The cells I cut were the brown and gold wrapped “protected 4000 ma” batteries. Well, it did say so on the label! Reviewers on Amazon give this cr@p 5 stars?

Hopefully some slick lawyer could nail Amazon then it could start to roll down hill on the importers to stem the flow >)

Some one has to get hurt first?

You’d have to search for a while, but there have been several reported incidents of ultrafire “BRC” cells (in all of their various iterations & colors) exploding, leaking, overheating while charging, and reporting some of the lowest capacities of any “new” 18650 we’ve ever seen. This one certainly stoops to new lows. Regardless of which version BRC you might find or how new they might appear, please do not use them and recycle them immediately. That can probably be said of most Chinese lithium cells… pure garbage sold to the unsuspecting.

What did you find inside when you cut open those Brown & Gold wrapped 4000 ma cells?

I notice that 18650s are beginning to appear in other products such as this radio:
Tecsun pl-880
I’m sure the radio community will receive the 18650(kHz) message.

When I first started “playing around” with cree lights I bought some grey/blue trust~ultrafire 18650’s as I didn’t know any better back then. It’s only when I got myself some lights with some serious firepower that I realized that those **fires were junk. These days I’m more picky about the cells I use. I would also avoid any super-cheap deals on batteries as well. More likely than not they’ve been pulled out of old laptops and re-labeled. :expressionless:

I saw my first 18650 battery in the Tomtom Go 710-910 series of GPS units which came out around 2007. I have seen some units recently with what appear to still have their original battery and it still holds a charge to some extent. Changing that battery requires patience and some skill.

You just megahurtzed me from laughing. :_(

I like the frequency of your posts.

Your transmission is breaking up, you need another repeater station

Not surprising… They do the same thing with AA and AAA for a very long time…

Nearly all chinese made cells dont even work well as slingshot ammo. Their average density is to light to provide any kinetic energy downrange.

They work quite well as rifle targets though. :slight_smile:

Just fill the hollow point with mercury before firing?

When i was a noob in the lithium ion world i bought several of these batteries,

now i want to dispose of them safely how do i do this in the UK

They tested 700ma on hobby charger. When cut I was disappointed not to find a miniature cell or white powder, just a plain low capacity cell. No matter how hard I shook it, the other missing 3300ma were never found along with vent or PTC. Over and under charge protection were also clearly printed on wrapper in engrish, lol.

@ Pilchman; Do you not have battery disposal stations at schools or big box stores like Lowes or across the pond equivalent?

Not that i know of, we have a council run dump in the area they might take them.
