There now IS a Samsung “58E” 21700

[BatteryMooch]

March 30, 2025 edit: I posted about this a while ago to my patrons, there now is a Samsung 58E floating around…model number CC5733F101 Ver A with “58E” on the can.

The CC5493F101 Ver C discussed below is still definitely the 55E and not the 58E.

*********************Original post follows***************


Here’s why I think this is true…

• Nkon and others have called this cell the “Samsung 58E” (see photo 1) but that’s not on the cell and there’s no mention of that designation anywhere by Samsung, not even in the datasheet.
• This cell was given the model number (new format) of CC5493F101 and that’s what is on the wrap (see photo 2) and used in the datasheet (see photo 3).
• This cell has a 5330mAh min/5490mAh typ “standard” capacity spec (see photo 3), much too low for a number like “58E” to be used. Typically these short model numbers have been pretty close to the nominal/typical capacity spec. Samsung does not play capacity ratings games.
• On the metal can, near the top where Samsung includes the short version of the model number, there is “55E” (see photo 4). This is perfect for a 5490mAh typ capacity rated cell like this one.
• EVE is releasing a 58E (photo 5) and I think someone got confused early on and it was just never corrected.

Unless there’s some good evidence somewhere that this cell is actually the 58E I’ll be calling it the “Samsung 55E (CC5493F101)” to help introduce the new model numbers and make it easier to confirm which cell I am referring to since the new number is on the wrap.

Another option that is offered is that the capacity is marked by character 3 and 4 in the new Samsung "CC" marking. So "58E" with CC54xxF101 could mean (5400 mAh) and "45T" with CC45xxF101 then mean (4500 mAh)

That makes a LOT of sense!
Wish they could have used “CC55xxF101” instead to match the “55E” designation on the can but perhaps there are typical vs minimum vs rated capacity considerations here.

I’m wondering if we can go another digit farther…

The 55E has a “standard typical capacity” spec of 5490mAh and is “CC5493F101”.
The 45T has a (rumored) “standard typical capacity” spec of 4500mAh and is “CC4503F101”.

So it appears we can pull out “549” for the 55E‘s capacity and “450” for the 45T’s capacity?
This leaves “3F101” on both cells still a mystery. I’m assuming CC = Cylindrical Cell?

And the “Revision” code in the lower left.

is there as such thing as a single '58' something cell that actually measures 5.8AH?

I think the highest i've seen is a 5.6ah and it was a Lishui or something Chinese..

They’re up to 6Ah now, the Vapcell F60 is one example. I forgot what the consensus was regarding which cell they’re wrapping…FEB? Delivered over 6Ah in my testing: Bench Test Results: Vapcell F60 - 12.5A 6000mAh 21700

6AH measured?

6AH measured?

Updated my post with a link to my test report…sorry for adding it late…6065mAh and 6087mAh IIRC at standard 0.2C rate to 2.50V.

Such a philosophical thought:

Suppose I am willing to accept that traditional cell manufacturers like Samsung, LG or Panasonic hide all parameters from anyone who does not order disgustingly huge quantities. (The fact that there are at least elementary datasheets available for their products is the work of the authorities who forced them to do so under threat of violence). But what I don't get why their markings are classified information as well and especially the existence of new models in general.

And it amuses me how surprised they are that their new products are no longer in demand.

Conspirational thought: the Korean/Japanese battery manufacturers are starting to be scared by their Chinese counterparts, so they're preferring to work in secrecy.

Definitely some interesting things to consider!

The flood of “faulty battery” lawsuits by individual users that blew themselves up led to the adding of warnings to cell wraps. I’m wondering if these new model numbers are just an extension of that practice, hiding whatever they can to confuse everyone. This might help slow down or prevent the sale/purchase of these cells by small vendors/individuals. None of us are ever supposed to be able to buy or use or use these cells and the big customers will be told everything about them “behind the scenes”.

Another possibility…plans for a significant expansion of available model numbers? Or perhaps the market is just getting too crowded with similar models numbers that don’t allow for clear distinction between the offerings from different companies?

Hmm…actually, that last one makes a lot of sense to me. For example, having 40P, 40PL, JP40, 40T, 40TG, H40A, and others all for 4Ah power cells makes it hard for a company to make theirs stand out and causes confusion. Going to these longer numbers allows for additional information and differentiates their products from others.

Perhaps a combination of hiding things AND product differentiaton? A win-win for them?

I’m sorry…which issue?
That’s the 50GB and it should have 50G on the metal can near the top (visible through the wrap).
