Great! Good to see Ultrafire up their games. Now wait for GB promotion.
Thanks for the review HKJ! :+1:
I believe it too.
Here we differ.
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.
Why??
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.
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 :confounded: :person_facepalming:
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 !
Have a look:
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.
a german shop too
I bought them recently:
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 :confounded:
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. 
Wish i would have known I would have got more than 1 pcs. :rage:
.
Liion is recommending this battery instead (Vapcell 1100mAh - 10A): Vapcell 18350 10A 1100mAh Battery - Genuine - Wholesale Discounts – Liion Wholesale Batteries
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):
“Discharge: 5A Max Continuous (PCB Limit)” https://www.imrbatteries.com/efest-18350-900mah-protected-button-top-battery/
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.
