Test/review of Keeppower 18350 1200mAh UH1835P (Black) 2017

In US, I think RTD Vapor has these.

https://www.rtdvapor.com/keeppower-imr-18350-1200mah-10a-2pcs/

I hope this becomes available somewhere with international shipping, getting popular 18650s is already hard enough, with 18350s it’s even worse

Woohoo, 1200mah is back on sale!

where?

:wink: And some other AliExpress stores have them :wink:

…and the wink is because? Is there a group buy in the make?

Eheh, no no - at least not that I know of! I just used the :wink: because there are several stores with these 1200 (un)protected Keeppower, I keep them under sight in case I need more to replace or add to the Aspire IMR18350 1100mAh I bought when they were still produced!

And because I use a lot of smiles on my messages :person_facepalming:

I believe these cells are still being produced by Shen Zhen Yong Deli, it's great to see KeepPower marketing them.

Cheers :-)

thanks for the links and info

fwiw, protected 18350 are longer than unprotected.

For my PT-16, the unprotected work, the Protected are too long

Can not deliver to United States”

Thank jon_slider :wink: Apart from 2 Panasonic 18650, I don’t have protected Li-Ion cells, but I am aware those are normally longer and thicker than the non protected :+1:
Also, didn’t check the shipping from that store :person_facepalming: But there are some other stores that have those and that probably ship to the US :wink:

This appears to be the same cell under the wrapper as the Aspire 18350.
I’ll stick with the Aspire for now since I can get them in the US and cheaper.

Thanks for the review HKJ, very much appreciated. :+1:

surprisingly, to me, the 16340 protected and unprotected are the same length (in inches), or 0.25 mm longer for protected.
The 18350 difference is much greater (IF the linked specs are accurate)

Protected 18350:
https://www.batteryjunction.com/efest-3400-button.html
Height: 1.47” (37.36 mm)

UnProtected 18350
https://www.batteryjunction.com/efest-4084-opt.html
Height: 34.63 mm

Added length of protected 18350, 2.73 mm

Protected 16340
https://www.batteryjunction.com/efest-3540-button.html
Height: 1.33” (33.98mm)

Unprotected 16340
https://www.batteryjunction.com/efest-3277-button-700mah.html
Height: 1.34” (33.98mm)

Added length of protected 16340, 0.25 mm

This store is currently shipping the Keeppower UH1835P to Brazil and I imagine other countries where shipping is often unavailable, I’ve bought keeppwers from them before (currently unwrapped and returned to unprotected panny-B state)

These cells are now in stock from nkon.nl, a highly reputable European vendor (no affiliation).

They do however state that the cells are 39 mm long. Which makes me wonder if they’ll fit properly in my Emisar D4?
The springs should have enough play, but I’ll hold my order until I at least get home and try to cram a measured battery with a spacer in there!

Or can anyone verify that these cells will work in a D4?

HKJ states 35 mm though, and “highly reputable” is the least of his accolades. But different batches, different specs? Fake cells? Or just misspelled on nkon?
I’ll be back with a solution to the conundrum when I have it, unless solved by another.

35mm is unprotected cell and it can be seen on my photo that the cell is unprotected.
39mm is a protected probably button top cell.

Nice cells, allowing small lights with multiple emitters to shine, the closely resemble the Vapcell 18350 purple.
Still, the Aspire cells were even better but extremely hard to gome by………

Tnx for testing!

Cheers,
Nico

I have the aspire 1100, keeppower 1200, and the vapcell 1100, pretty sure the only difference is the wrapper.

Hei Imp…

My
Aspire 34.91 long (fit D4)
Keeppower 35.09 long (fit D4)
Ultrafire (protected button top) 38.78 long (do NOT fit D4)

So there you go…

I received an answer from nkon. Despite the time being post 5 pm on a Friday!

So it seems like they’re fine. Although Hunter’s post makes me curious as to the measurements and batches, if nothing else…

I’ll order a bunch anyhow!

Hi Imp…

Yes it must be batch variations. Mine Keeppowers are 35.09 to 35.19 in length and 18.27 to 18.29 in width.

Otherwise, exactly the same battery as described.
