Hi HKJ;
As many of us buy Sofirn lights with the included battery, could it be possible to test some of them. Your site has the 14500 / 900 mAh cell only.
I’d think Sofirn would oblige in sending you some samples.
Thanks…
Hello Henrik,
Looks like your site suffered some sort of mess up with your latest battery review, the Samsung 50G one. First and foremost, the link to it in the main page got a big picture of the cells attached to the review name, making the cell “the star of the show”:
In second place, certain graphs in the review are “out of scale”. …
Everything fixed.
Just to point this out.

Hopefully fixed now, but it may be an hour before the website is fully up to date.
The new Vapcell T50 21700 battery looks interesting. Some here have said it contains a Samsung INR21700-50S cell.
Have they sent you samples to test?
I do not know if they have send me any, but I have not received any.
Could you test Sofirn’s batteries?
Sure would be nice to know their actual capacity and current capacity.
Hi HKJ
Sorry, things are busy recently,
I forgot to tell you that we sent the sample T50 test a month ago
thank you
Just check the tracking number. It’s very slow. It hasn’t arrived yet

Hi HKJ! A few of us would be very interested in the T50 testing. Understand the shipping has gotten really bad and you have a backlog queue.
I was lucky to receive 4 of these but they have been scarce - limited qty, sold out quickly, waiting for re-stock.
They look impressive with having excellent performance and high capacity in a 21700. If you received them, and could give us an approximate time frame, that would be much appreciated.
Thanks!!!
Vapcell K64 6400mAh 26650 battery. It looks like you will have to increase the maximum in your 26650 comparator.
Vapcell might as well also ship a sample of the Vapcell INR 18350 F14 1400mah 3A 3.7V Li Ion Battery with it unless this has already been tested
I would guess the result will be very similar to the Keeppower 18350 1400mAh P1835C3 published today. What are the odds of two different 1400mAh cells released at the same time? None.
Did not know Keeppower also released a 18350 1400mAh, hopefully they’ll follow suit and release a 26650 6400mAh. They probably have the same suppliers/contacts.
Here’s a new source, perhaps, for NiMH (found at Amazon)
POWEROWL Rechargeable AA Batteries, 2800mAh High Capacity Double A Batteries 1.2V NiMH Low Self Discharge (Pack of 12)
They have a store that also sells AAAs and a couple of different chargers.
Inexpensive, which makes me wonder if it’s just a new shrinkwrap on known cells, or an actual new manufacturer.
Have you tested these Molicels?
M35A 18650
M50A 21700
Hi hkj, are you planing to review Liitokala Lii-600?
No.
I have not done any charger reviews lately and do not know when I will again.
Can I leave a request for Sanyo 18650GA 3500 mAh? I used them several times and they broke quite often. On https://batterytools.net/ I have read several reasons for battery failure. For example wrong coast charge voltage, free inter-cell joins or associations, misfortune of electrolyte and tall and uneven temperatures. Like this, I have not noticed, and so I don’t know what to do. Can you tell me what is wrong with these batteries or maybe they have features in use? Thank you in advance.
I would like to see Amazon Basics NiMH Size C & Size D batteries tested. And the new Tenergy Premium Pro’s Size AA & AAA.
Thanks
Just stumbled across “Ockered” and while they have scammy products (18650 with 18000mAh), they have some others that could be kinda OK?

Was about to order them, but I basically only have high drain applications and the maximum current is not something I can test.
