Review request for HKJ [Rechargeable Batteries]

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.

Test of Sanyo/Panasonic NCR18650GA 3500mAh (Red) @ lygte-info.dk

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.

I see just 3 entries for such a thing in AliExpress, out of which just this one is selling it in small quantities. The size is nearly a match of two C cells (26500) in series.

Nothing to write home about capacity or energy density wise. The «8C» discharge rate claim is the only somewhat noteworthy stuff. I wonder what is the target market for such a thing.

Energy density in batteries available to the public hasn't increased in the last 6 years or so, by the way.

@ L4M4:

Rather than taking your chances with Ockered, I’d go with Sofirn’s offering (SofirnLight.com).

Previously they were labelled PLBs (the 5000 mAh) and I believe these would be equivalent to Schockli 5500 mAh (lygte ). I just so ordered some, good pricing (for 2) and free shipping with orders above $29 (USD).

But if your query is for HKJ to test, disregard my post.

Some of the buyers on Aliexpress have tested the capacity (look at the reviews), and the real capacity is much lower.

Is EVE 33V a rewrap of another battery? Can’t find much info on it.

no,33V have datesheet

Does Vapcell have a rewrap of these EVE 33V battery? (there are too many Vapcell 18650 battery models right now, and it gets a bit confusing, which is a rewrap of which battery internally)

Vapcell F32, welcome to purchase
33V

Yes, there are many vapcell batteries

Any updates on K64?

I’d like to see 9V lithium rechargeable batteries evaluated.

The 26800 has become popular here. What can we do to help you test this one?

A test of the 5th gen Eneloop would be much appreciated : Overview: All Eneloop batteries 2005-2023 - #842 by ChibiM

Hello! :-)

More or less recently I've noticed the appearance of a new 21700 format, 3000 mAh rated capacity LiFePO4 cell. This could be the highest energy dense LiFePO4 cell in the market, if it meets its claims.

I've been conversating with the creator company of this cell in Alibaba, and with one of its subsidiaries, and all is fine as far as I can see. They provided me with a couple datasheets which in practice are the same, you can take a look at them here:

The cell can be found for sale in AliExpress but it's not widespread; I have a couple sale links.

By the way, is Henrik lying around? Did he went on vacation?
