3400mAh Panasonic NCR18650B

[Colonel Sanders]

I have some of these cells on order and will be posting some test data soon after arrival.

I still don't know for sure if these cells are intended to be charged to 4.35 or 4.2v. Anyone know *for sure*? Thanks.

[Colonel Sanders]

According to Keeppower's website, it is 4.20v.

[Shadowww]

Considering it's just a updated NCR18650-series, I'd also say it must be 4.2V, if it'd be 4.35V it wouldn't be NCR, it'd get assigned some other series-name.

[bshanahan14rulz]

officially 4.2V. may gain up to 100mAh from 4.35V charging, in some of the more extreme examples, from what I hear.

[jirik_cz]

I can confirm they are 4.2V. Just did a first discharge and got a claimed capacity from a cell charged to 4.2V...

Awesome, thanks!

At what voltage did you end the discharge?

[tobrien]

what do the letters at the end (B) for example, signify?

[Colonel Sanders]

I don't know but the A model was 3100 and the one with no letter at the end was 2900.

[jirik_cz]

So, here are some of my graphs and I have to say that these cells are very impressive! Tests are done with CBA II.

[Colonel Sanders]

"and I have to say that these cells are very impressive!"

Wow! I'd have to agree! Very nice. Thanks for the graphs. I really like that you included the mWh data as that's really what we should be looking at instead of mAh.

[czAtlantis]

where do you buy them? cnqualitygoods says "Sorry, Out-of-stock and stop sales. Would you want to book in now and reserve the product?"
Thanks

[space-cowboy]

Yes, Panasonic NCR18650B is even better at higher current.

Excellent handling voltage sags.




FYI


3.192mAh @ 5A,

3218mAh @ 3A

[windstrings]

looks like they are already out of stock.

[tobrien]

orbtronic has them in stock but at $19.99/unit

[RI Chevy]

Thank you for the graphs.

Yeah, that's a tough one--get two 3100 unprotecteds for $17.98 shipped, or one 3400 for $19.99 shipped?

I'm going with the former, I think.

This shop has very good price but shipping to my address is 20USD via standard airmail :-/.

Even 20.00 bucks is only 5.00 more a piece if your ordering 4 batteries.... If I don't mind the slow boat from China.....

think I'll look a tad more first....

[czAtlantis]

For larger quantities it is not a big deal but I just want one piece for test. So I am looking for some shop with "free shipping" where i can get it for ~15USD shipped max.

Hope your Inbox is clear, as you're about to get flooded!

Here you go fellas (for females too)! Here are a couple of links I have provided just for you, with the first one being to the Panasonic Industrial's official web page for their new 3400mAH "NCR18650B" where it includes a wealth of information and also links to various specification and data sheets. The second link is to a page that explains the chemical makeup of the new Panasonic NCR18650B batteries and what they have actually done to increase their capacity from 3100mAh up to 3400mAh. The page that I have linked to is actually a Google cached version of it, as by doing it this way for you it should hopefully highlight any occurrences of the wording "NCR18650B" on the page so that you can cut right to the chase and therefore save yourself both some time and some effort. I really hope that I am allowed to do this, and I also really hope that you all like it and that you find the information to be of some assistance!

P.S. I really hope that these all work just as I had planned, especially the link to the Google cached version however I am pretty confident that they will!

>In the consumer sector, Panasonic’s NCR18650 2.9Ah and 3.1Ah models have used an HRL on the anode and hybrid-type separator with an alumina layer, but the 3.4Ah NCR18650B will not have an HRL on the anode.

Does this essentially means NCR18650B is not as safe as NCR18650(A)? :/

Would you mind explaining what HRL means?

[Phil Ament]

Would you mind explaining what HRL means?

HRL stands for Heat Resistance Layer
