Discharge curves looks very good, the cells tracks nicely and can deliver 7A, at 10A the voltage is a bit low.

Conclusion
It looks like Ultrafire has got their hands on the best 18350 batteries around and then added a protection. The protection will increase voltage drop at high current.
If they keep making the battery this way it will be a good battery.

Thanks for the test HKJ!

LOL, there is not much we can trust when it comes to budget products from China, but there was one thing we could rely on: Ultrafire batteries are cr*p. Now that last straw is gone. Party

The capacity is close, but these do not keep the voltage under load as well as the Aspire 18350, there still is a clear performance gap. And at 5 dollar/cell these are not cheap.

The difference between protection and unprotected cell, remove the protection circuit and my guess is that they will match the Aspire at any load.

Thanks a ton HKJ!
Frankly, I used to think that your tests of *fire cells serve nothing but a proof for noobs…and you’ve got enough of such proofs already.
But now you have found a gem. Party Big Smile

Maybe, I do not trust Ultrafire, nobody knows when they switch to another cell inside the wrapper.

Yes. I’m pretty sure they will disappear or be replaced soon. I view any buys of these cells to be risky, but that’s probably the last chance to get the real deal. A worthy replacement may arrive any time or may not arrive in years. I’ll take the risk of buying junk.

It’s not easy to remove the protection circuit on that type, protection design, of cell. I ruined a RCR123A four sevens cell trying to remove the top hat style that this also appears to have.

Be Careful!! if you try.

The brief information we got from Neal is that the 18350 size is becoming obsolete in vaping, and sales were not enough to continue production.

Are there other brands that re-wrap these cells with their own brand (and without protection)?

This is not the first good UltraFire cell though.
I bought a USB rechargeable 18650 some time ago, rated 3400mAh and it had a decent LG cell under the wrapper.

Like you said: reliability has more to do with predictability than with a decent performance.
It’s just like my old manager. If things went OK, he re-named your work. If not, he was the first to do a Brutus on you.
You could trust him (tot do so). And looking over your shoulder without moving your head is good for the eye-muscles.

@Jerommel I have a pair of silver Trustfire 14500’s that are way better than Olight or Nitecore cells.

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

Well that’s a pleasant surprise. I was expecting to laugh at a 350mAh cell.

Lol, I wonder if we have been missing out on 10000mAh 18650 cells all this time Sick Facepalm

UltraFire is an 0K quality brand, some of their stuff is quite good for the price. However, for whatever reasons it is counterfeited. At all events, searching for whatever product in their official website is a wise advice.

Take, for example, this “ultrafire sk98” search at FastTech. Only this SKU is genuine right now (and the tailcap switch is crap, by the way).

The Aspire is still available ! But they label it as 1.100 mAh nowadays, as the 1.300mAh were a little bit to optimistic !

It is not available anywhere in China. I see that there are still some US shops which haven’t sold their stock, but shipping to Europe is prohibitively expensive.

I tried to buy them there before but there is a silly bug in their site: you have to select your country in a list and that list is incomplete, many countries are missing, also the Netherlands. And there’s no way around that so I can not order Sick

No Poland either.
But it (together with US shops) shows my comment about lack of availability was much stronger than it deserved to be.

Gone, gone, gone…

I just received an order from Liion recently and got the Aspire 1100mAh, but checking today it’s no longer available at Liion Wholesale or IMR Batteries. Sad Wish i would have known I would have got more than 1 pcs. Angry

.

Liion is recommending this battery instead (Vapcell 1100mAh – 10A): https://liionwholesale.com/products/vapcell-18350?variant=6132565278752

I wonder if it’s as good as the Aspire?

I’m not too good at understanding the graphs (probably don’t have the patience to figure them out)

Can someone answer a few questions:

  • Are they are truly 1100mAh?
  • These are better (higher capacity, higher discharge) than the Efest 900mAh protected?
* In the review it shows the Ultrafire’s will deliver 7 to 10A, so the protection circuit on these have a higher “ceiling” than the Efest 900mAh protected?

(Efest’s show current being limited to 5A by the protection circuit):

It was my understanding that the Keeppower IMR 18350 1200 mAh battery from RTD Vapor was the same battery as the Aspire. I picked up a couple to have on hand when I finally decide on either a Astrolux S1 or a Convoy S2+, both with the shorty tube.

Look in table, they are above 1100mAh up to 3A.

Definitely, this new generation is way above anything previous.

Thanks for the info, probably gone too…

The only KeepPower 18350 I see currently on that site is 750mAh, and it’s out of stock.

Thanks for the reply. I guess the protection circuits are new generation too (with higher discharge limits)

That’s the whole reason I purchased the Aspire 18350 cells. They work great but short run times compared to a 18650.
Thanks for the testing data HKJ. Thumbs Up

These are nearly certainly exactly the same cells as:

  • Aspire 18350
  • Keeppower 18350 1200 mAh

However, I wouldn’t trust Ultrafire. They may change the cell they use under the wraps at any point.
Therefore I would prefer to buy Keeppowers unless:

  • UF was so much cheaper that I could justify the risk, or
  • I was capable of measuring the cell cell receive AND getting money back if it underperforms AND got it cheaper to justify the potential burden
