aspire 18350 discontinued..?

The Aspire 18350 batteries were discontinued by the manufacturer, anyone know why, or who has some still..?
Weren’t they the highest capacity and highest discharge rate of any 18350, by a large margin..?

MTN is out and can’t order any more.

Were these re-branded, if so who was the manufacturer, and do they still produce them..?
Is there a better 18350 out now..?

Many unanswered questions…

I was hoping for a 16340 from the same factory.

Hopefully a brand like Keeppower will use these cells.

Keeppower has a 1200mAh cell that seems to be the same thing, currently available from RTDvapor

If anyone’s interested, check out your nearest not-yet-defunct Rat Shack for their probably discontinued stock, namely their “DE” (“Digital Energy”?) cells.

I got a pair of 16340s (using one in my Jet-II) and a pair of 18350s. The latter are rated 800mAH, but after running them (twice!) through my C3100, I’m getting just a shade under 900mAH from both! 893mAH and 898mAH or something like that.

I’m tempted to put my 16340s through them, and my single 26650, and check their ratings. If they hold up, Hell, I’d be tempted to order a few more of at least the shorty cells. (Got enough LK 26650s.)

They’re protected, so I doubt they’d push all that many amps out the door, but you can always unwrap/strip/rewrap the cells.

Just a somewhat surprising alternative if you don’t need real Aspires. Big Smile

Lionwholesale is out now, too. I got three earlier in the week. Now, I wish I’d ordered 3 more.

This non-political signature is not non-political.

The KeepPower UH1835P is the closest performing cell in HKJ's comparator, possibly from the same OEM as the Aspire.

I just bought 3 from there. I really like the battery, so I thought, I better stock up on a few more before there gone.
The keeppower is the same battery from what I have seen of HKJ’s testing as mentioned above.

Hey guys, these are indeed discontinued, but we have a replacement now. The Vapcell 18350 is the same thing as the Aspire was under the wrapper, and we now have them in stock.

Thanks for that info. I got three of the Aspire 18350s and two of the VTC-5As from you before 1/20, when my Emisar D4 arrived. I’m good for now, but it’s nice to hear about our options.

Not doubting what you advertise, just want a confirmation.
You website states max discharge 10amps. no word of the 15amp pulse rating..? Have they been tested for capacity, are they truly 1100+ 10/15a like the aspire..?

The Aspire 18350 1100, were rated at10/15amp, 10a continuous and 15amp pulse for up to 10seconds.
HKJ tests have confirmed this rating.

My Aspire’s will do 15+ amps pulse on my D4 with a reasonable/acceptable voltage drop no problem. Aspire is/was the best 18350 I’ve used by far.
Will your Vapcell 18350 do this also without a drastic voltage drop like most all other 18350 have..?

I do need to order some 18350, but want to be sure of what I’m getting.

Thanks Jon

Yep, it’s the same. Here’s a pic of the 15A pulse test, 10 sec on 5 sec off. You can see they’re within test to test variation of each other. Vapcell has been very conservative with their ratings so that’s the only reason for the difference in published numbers.

Thanks for the reply Jon.

I will put in an order to try the Vapcel 18350.

Do you know who actually makes this cell, not who rewraps it..?

Yes I do know who makes it, it’s a factory in China. They don’t sell it to retailers though, it’s only sold rewrapped.

The battery itself hasn’t been discontinued, just Aspire (the E-Cig company) isn’t putting their label on them anymore. Which is somewhat strange since Tony (owner of Aspire), apparently has a stake/part ownership of this Yongdelli battery company. But like any Chinese company, if you order enough of them, they will make them.

Also, the flashlight business isn’t even a blip on these battery manufacturer’s radar. It’s all about the world-wide e-cig business.

Awesome. Smile

Plus, they’re metallic purple. It’s hard to go wrong with metallic purple.

They actually have some pretty cool subtle white flowers that look like they’re straight out of a Japanese garden around the negative end, definitely the prettiest battery I’ve seen recently. So there’s that Silly

Thanks for this information. I’ve been wanting one of these for a D4.

I’m also interested in some 30Q button tops, among other things. Will be placing order soon.

I wish there were more 18350 flashlights. Now that we have a decent small cell it should be the standard for all new smaller lights that typically would take the RCR123. Unfortunately being a little wider and more than a little late it’s not going to happen very fast if at all.

I wished there would be a better 16340 cell. There used to be a high current 550mAh AW cell (the AW 16340 15C) but that one has been out of production for ages. I bet that if the right manufacturer is willing to make it, a 800mAh high current 16340 cell should be feasable.

“I used to think that top environmental problems were biodiversity loss, ecosystem collapse and climate change. I thought that thirty years of good science could address these problems. I was wrong. The top environmental problems are selfishness, greed and apathy, and to deal with these we need a cultural and spiritual transformation. And we scientists don’t know how to do that.”   (Gus Speth)

If you go by cell to cell volume, and use what ever they figured out in the 18350 cell, A little over 800 mah should be possible.
The best high current 16340 cell I have tested is the Trustfire IMR16340 650 mah. Who would have ever guessed, someone figured something out that worked better over the pond. Still not on par by volume with the 18350 cell but maybe its coming.

If my math is anywhere near correct, applying the Aspire 1150maH 18350 tech to other form factors should give us about…

  • 32650: 9051 mAh
  • 26650: 5587 mAh
  • 20700: 3197 mAh
  • 18650: 2262 mAh
  • 18350: 1150 mAh
  • 14500: 870 mAh
  • 16340: 817 mAh
  • 10440: 272 mAh
  • 10180: 95 mAh

Something doesn’t add up there, since some of those are way off. Like, 18650s are up to 3500mAh now. Perhaps we should look at how things might be if we could apply 18650 tech to other sizes:

  • 32650: 14000 mAh
  • 26650: 8642 mAh
  • 20700: 4946 mAh
  • 18650: 3500 mAh
  • 18350: 1778 mAh
  • 14500: 1346 mAh
  • 16340: 1264 mAh
  • 10440: 421 mAh
  • 10180: 147 mAh

To estimate, I’m just multiplying the volume ratio by the capacity, where the volume is estimated as the inner cylinder with a wall thickness subtracted from both diameter and length. I tried a few different wall thickness values, and the thinner the wall the better 18650 looks compared to the others. These values used a wall of 2mm.

Without disregarding your estimations at all, a problem I find is that if we define actual useable cell capacity as the minimum tested cell value at ≈0.2C discharge ratio down to 2.8V, the “3500” mAh cells do not meet a 3500mAh rating, it's more like (barely) ≈3350mAh for the Samsung 35E, 3250+mAh for the Panasonic/Sanyo NCR18650GA and (barely) ≈3200mAh for the LG INR18650-MJ1.

Okay, same calculation, but using a different capacity:
./mah.py 18 65 3250

  • 32650: 13000 mAh
  • 26650: 8025 mAh
  • 20700: 4592 mAh
  • 18650: 3250 mAh
  • 18350: 1651 mAh
  • 14500: 1250 mAh
  • 16340: 1174 mAh
  • 10440: 391 mAh
  • 10180: 137 mAh

I’d be pretty happy with a 1174 mAh 16340 cell in my little Olight S-Mini. Smile
