Test/review of UltraFire 18350 1100mAh (Black-red)

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).

Cheers

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:

https://liionwholesale.com/collections/batteries/products/aspire-18350-battery-10a-15a-1100mah-genuine-and-tested?variant=37706165649

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:

https://www.dampfplanet.de/Akku-Aspire-INR-18350-1100mA-15A

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. :frowning: 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.

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.

Safe to use these with D4?

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. :+1:

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

This is weird, doing a search on that site there’s no Keeppower 1200 coming up…but if I do a google search they come up:
https://www.rtdvapor.com/keeppower-imr-18350-1200mah-10a-2pcs/
EDIT: I searched a different way on the site and found them there.

I wonder why that is? But anyway I can put them in the cart to purchase, and shipping is only $2.99 which is less that what gearbest is charging me to ship a pair of the UltraFires, and a little over $3.00 less than amazon.

Thanks duvallite!

OR unless…

  • You want protected cells that still deliver high discharge current.

Just realized the Keepowers aren’t protected?

In fact aside from these UltraFires, I’m not aware of any other High capacity/High discharge protected 18350.
