Review request for HKJ [Rechargeable Batteries]

They where in my inbox, where I put everything I do not have time to look at when I receive it. I will start a test on them later today.

So, PKCell 14500 is already in the review queue…

How about the PKCell 18350 (IMR and ICR)?

14500 LiIon with 1.5V output. Is it just buck with stable 1.5 volts throughout the discharge?

They say 1.6 Ah and 2.4 Wh, so probably yes.

Saw the PKCELL ICR14500 review very recently, and remembered about the NICJOY cells (back in May!).

Did The Kraken sunk the slow boat they were shipped on? :-D

Fairly cheap and esteemed but, how good do they really are?

Test data have been ready for some time and they are in my internal lottery about what cell to publish next.

I am fairly low on 1.5V cells to test and have ordered them.

The NICJOY ICR14500 is probably the cell which would grab more attention here, its price is quite attractive.

As always, thanks Henrik.

Cheers :-)

I know HKJ will review them but I have bought them 3 years ago. (around 30 of aa and aaa) Some of them are still active while some of them died. Capacity seems nothing special comparing to quality alkaline 1.5V batteries that seems to last a lot longer …

Only advantage of those is that they are rcr imho so they save $.

Looking forward for review.

Sorry luminarium iaculator but, seriously? Those cells I pointed out are low self discharge NiMHs, alkalines can only do better under low drain applications.

Checked out the EBL AA 2300mAh NiMH review recently, top notch cells at an excellent price!

P.S.: pissed off right now, my smartphone screen becomes unresponsive or erratically unresponsive while plugged to a 5V 2A power supply which until now worked nicely. Very recently I used it to feed a DC-DC buck driver and I may have overloaded it, current at the emitter went up to ≈3.4A, @#$%!

A decent protected cell with high drain would certainly interest me to buy now that I have received my Q8

Keeppower has send me a pile of cells to review, but it will be a few months before I get to them, except the 18350, they will be published much sooner.

Hi HKJ,

I’m leaving these two suggestions, but also question: do you have any clue about these cells?
I’m not even sure if they worth a review, or if they were already reviewed (if so, I couldn’t find it).
Here are the links:

AWT 16340 550mAh: This product is no longer available.

MXJO IMR16340 700mAh: This product is no longer available.

Thanks and thanks for all your work :wink:

MascaratumB,

AWT IMR16340 550mAh (Yellow) @ lygte-info.dk

With regards to the MXJO, slim chance for its capacity rating to be accurate and even slimmer for its amperage one. And I do not mean to say they underspec their products, of course.

Cheers :-)

Minimum order 50

That is a bit too much, but I am fairly low om low capacity LiIon and NiMH cells, i.e. suggestions are welcome.

Thanks Barkuti! I knew I would get lost in all those AW and AWT! :person_facepalming:
Thanks for it and for the explanation about the MXJO! I think they will be less than advertised, buy, maybe it worth a try! Let’s see :wink:

Sorry HKJ, I had seen it elsewhere and now I found it! 50 pieces would be tooooo much to test :wink:

Through IMR batteries individual pieces are available! https://www.imrbatteries.com/mxjo-16340-700mah-button-top-battery/

If you wanna try them, maybe we can share costs (shipping and battery value), just PM me and we can arrange that :+1:

Generally USA dealers are impossible, the shipping are simply to expensive. A very dedicated dealer may ship to me (It is a couple of years since that happen last), but I will not pay UPS shipping for a few batteries. Chinese dealers are usual more willing to pay UPS for shipping.

Oh, ok! I didn’t realize that :person_facepalming: But you’re right, shipping from abroad is difficult in terms of values. Even in the Europe it is, I paid near 30€ total from buying 3 cells @ NKON (transportation costs were higher than the cells…).

Well, I just wanted to help if there was a feasible opportunity to test those batteries! In any case, thank you :wink: If I see them elsewhere, for reasonable prices, I’ll post it here !! :+1:

Shipping of LiIon is a big problem in todays world. The Chinese dealers try to find ways and often do at reasonable cost.
When a dealer/manufacturer sends me batteries for test they often want fast shipping and there the best options is UPS (for now), they often send many batteries i one parcel, making the “per cell” cost lower.
I do usual not care that much about prices, but I will not pay $20 (or more) shipping for a $5 cell.

I do sometimes see creative ways to get around the shipping restriction. I have a few times received some very cheap flashlights, with good batteries inside.

Is there any compilation of information about protection circuits?
I know they’re made by someone(s) and added to cells then shrinkwrapped.

I became curious after getting several “protected” cells that had problems — shutting off when a flashlight went to high brightness; failing to recharge after being reset (sitting in a charger cycling from 4.2v to 0v every few seconds, presumably because the charger was triggering the protection circuit).

If there’s a reliable source for protection circuits in appropriate lengths for 10440 and 18650 cells, I’d like to know where to find them.
