Test/Review of UltraFire BRC18650 3000mAh (Red-silver) 2015
UltraFire BRC18650 3000mAh (Red-silver) 2015

DSC_9732

Official specifications:
  • Material: Li-ion Battery
  • Suitable for Flashlight Torch
  • Capacity: 3000mAh
  • Voltage: 3.7V


UltraFire%20BRC18650%203000mAh%20(Red-silver)%202015-info

A cheap battery with very low capacity. The above list of capacity is a bit misleading, see below.

UltraFire%20BRC18650%203000mAh%20(Red-silver)%202015-info1

Here I have the capacity for each cell, one has 1600mAh, the other 350mAh and neither can deliver much current.

UltraFire%20BRC18650%203000mAh%20(Red-silver)%202015-Capacity

Very bad curves, different capacity for the two cells and very sensitive to load.

UltraFire%20BRC18650%203000mAh%20(Red-silver)%202015-PowerLoadTime

They could only handle a 10 watt load for less than a minute.

UltraFire%20BRC18650%203000mAh%20(Red-silver)%202015-Charge

When charging notice the huge voltage drop, the best cell drops 0.1 volt, the other 0.2 volt when charging stops.



Conclusion

This is bad cells, stay away. Check the link below for more information about it.



Notes and links

I disassembled the battery to see whats inside

How is the test done and how to read the charts

“This is bad cells”? How about, “These are, bad cells” :bigsmile:
Great review BTW, thank you. Before I knew any better, I bought 4 of these with exactly the same results you posted above. Their crap.

Can’t believe you wasted your time on this Shocked but it should probably be pinned as #1 thread in 18650 batteries section for all beginners that are convinced they have 4800mAh cells… Wink

How would (new) people know they are bad cell without a test?

The disassembly thread would probably be better to pin, it shows why they are crap.

Thanks for testing HKJ! Have you implemented the “skull” verdict in the battery reviews yet? Wink

Kind regards

In that case you would have to destroy/disassemble one or some quality cells so you could make comparison and say something like:
“this is crap cell, look what’s inside …. and this is good quality cell, notice how it looks inside…”
all followed by pictures that beginners could compare for obvious differences…
On other hand this graph says it all Big Smile

Not really, when a cell is corroded and has marks from welding of battery pack strips, you do not really need more.

I will probably disassemble some good cells at a later date.

Funny that the 3000mAh wrapper is still around since you can get that and/or more quality as well as capacity from reputable brands Big Smile

49% of the reviews on this Amazon site this gave the batteries a 5 star rating. I wonder how many of them are shills? Or is it “if it lights then the batteries are great” mentality?

Most people are just not aware that they have been blatantly misled and lied to. Pretty much like 99% of everything that we buy from there. They can do anything they want, they are exempt from us law. And boy oh boy, do they ever run with it. :Sp

One of the guys I work with brought in a Trustfire light with a Ultrafire BRC 4800mah battery. I sent him some articles on how dangerous they were and he immediately tossed it. I gave him some Sanyo laptop pulls (measured at about 2000mah) and he was totally amazed at the increased runtime. Another guy had a Ultrafire 14500 in his sk68 that had a runtime of about 5 minutes. I tested it at home and it measured out at 100mah. Gave him an A&W I had lying around and he was also impressed by the increased runtime.

Both are technical guys (a DBA and a network engineer) so luckily they were open to articles and reasoning. Took less than 5 minutes for them to see the light (pun intended LOL

My 2 good deeds this year.

I already advised peoples stay away from any Ultrafire batteries many years ago. They are extremely dangerous!
Unfortunately I lost the link for how these batteries exploded & this guy went to ER eventually!

I sure hope someone at Tesla sees this. They can cut-down on the number of cells they need by 1/3. I bet it also sags less and has a longer cycle life. I see on one site that 9 sucker buyers have already jumped on it.

There is a very small decimal point ..... you just have to look very very closely

Awesome review! I’m happy I never wasted any money on these cells because I spent a lot of time on this forum before spending any money on 18650’s.

Thanks for the review. Does anyone know what BRC stands for?

Three Tanna leaves to give him life, nine to give him movement. But what if he eats the whole bag?

BRC stands for anything you’d like it to mean really, since the entire wrapper is nonsensical: it does not really pertain to the battery inside at all, its just a wrapper purchased in mass quantities and shrinkwrapped over old cells or phoney cells with a capacitor in them in some cases.

I like to say it stands for “Brick” though: not only are they really bad capacity and cant deliver much current, but they also fail quickly and you get really few recharges before the dropoff in capacity renders them useless…when you buy these they’ll be bricks soon enough.

Tossed it where?? and when??

It takes a while — weeks or months — before crystals grow large enough that there’s a risk they’ll puncture the internal membrane.
