Review request for HKJ [Rechargeable Batteries]

BangGood got a notification from UltraFire to stop using their name, so MECO is the brand name they are using in place of UltraFire. That's the word I got from a BangGood rep. One day I noticed all UltraFire brands dropped from the BG site, so I asked. I was hoping they would bring back the UltraFire ZY-T11 clone under MECO branding, but it's not there, yet.

I sure wouldn't trust the MECO brand cells, same as not trusting UltraFire cells (real capacity, charge cycles, etc.).

Thanks for the heads up! They are SO CHEAP IT’S SO TEMPTING but since it’s a re branded UF I will stay far far away

Oh yes please.

Both the 3500mAh LiNiCoAl and the 3000mAh LiNiCoMn are pushed by the major brands at the moment and it would be very nice to compare GA, BL, MJ1 and 35E, as well as HG2 and 30Q with each other and its predecessors.

We all know that rewrappers often use these cells, but we never can be sure which it is and which one it will be in the future - as they are also known to bait and switch. Buying the Panasonic/Sanyo, LG or Samsung cells (from a reputable source) gives so much more value. There are only a few tests missing. Perhaps you could adapt your queue, slightly…

You can do this already if you research a bit and don’t mind German text around the discharge graphs.

Well, I truly don’t mind. But as of today even dampfakkus.de does not yet cover the GA, the MJ1 and the 30Q in the range of 2-5A.
And the HG2 was only added in the last 48 hours. :wink:

dampfakkus has a big advantage compared to me, they do not test at low currents and only test one cell! This means they can do their test in one or two day(s) and not one week as I need.

Can’t thank you enough for your thorough testing. That’s why I would never ask for a change in testing procedure - but I do second TomE’s motion for a tiny little shift in the queue.

I was not talking about dampfakkus.de, but the German flashlight forum. Just google battery name + “test” and you’ll find it.

Edit: I don’t see any rule forbidding links to other forums so here we are:
Samsung INR18650-35E
Panasonic/Sanyo NCR18650GA
Samsung INR18650-30Q

That is right :wink: here at BLF we aren’t scared of information from other forums :smiley:

And here are the same links but auto translated to English :slight_smile:

Samsung INR18650-30Q

Samsung INR18650-35E

Panasonic/Sanyo NCR18650GA

And i have to chime in on the request for HKJ to put these new cell at the top of the queue. The real original cells from Samsung, LG & Sanyo/Panasonic needs to be tested before the rewraps if they are available.

Here is another list of recent battery tests. I believe most of the tests are at higher currents.

Ok, got it. But following the links I don’t see graphs or charts, TLF seems to suppress pictures, so it’s not that useful.

Normally it doesn’t. Pictures appear even when I’m logged out. Must be some other problem.

Edit: apparently it actually does if you’re not registered (tried in incognito mode). Not nice. Sorry. You could of course register to TLF, it’s free and doesn’t hurt :wink:

Please test the AOSIBO IMR18650 60A 2600mAh cell, they claim incredible performance :open_mouth:

I hope it is true, we can always use a stronger 18650 cell :slight_smile:

They are curiously heavy for a 18650 at 50g, that is even heavier than the 3600mha Panasonic at 48,5g & most 2500-2600mha is around 44-45g. Maybe they really have found some new special component…….

These look interesting also

AOSIBO IMR18350 800mAh 15A

The same, but different wrapper?

30A cont, 60A “pulse”

I don’t think it is the same cell, to much is different.

Old 30A/60A cell
46g
18mm
New 60A cell
50g
18.3mm

Plus the + pole looks very different.


But who knows maybe they just have an extra layer of rewraps, that could account for the extra width & weight.

Please test the Vapex AA 2500mAh low self-discharge Rechargeable batteries

On order

I do only have a few NiMH in queue, but I do not know when I will test them (The test station is used for chargers at the moment).

MJ1! LG Chem 18650 MJ1 – 18650 Battery | BATTERY BRO

Efest IMR 3000mAh.

I think… That all the 3Ah rated IMR batteries we are gonna see from now on should behave very similar to the 30Q

anyway…i do not know if HKJ has the necessary stuff to test 200/400A peak currents but it is now few months I’m intrigued by this
