what's the highest capacity 14500 cell?

Thinking of getting a couple of 14500 cells for my Sipik sk68. I’ve seen Trustfire Flames very cheap and they are stated as 900mAh. There are also red Sanyo 14500 that are 850mAh a bit more expensive. Has anyone measured any to be higher than 900mAh?

I don’t think I’ve seen anything more than 900 mAh, and even then it’s unclear what the actual capacity is.

The highest capacity I could find we’re the nitecore 14500, the claimed and true capacity is 750mAh(4.2-3V)
There is a Sanyo cell in it.

The best ones AFAIK are the Nitecore linked by werner

Also I have been using these ones http://dx.com/p/trustfire-protected-14500-3-7v-900mah-rechargeable-lithi... for more than 3 years (I have ordered some packs).

However the Nitecore (sanyo inside) perform better under the highests loads. For 5,99$ you get only 1 Nitecore. For 5.49$ you get 2 TF…

I have the TF flames too, two are good 2 are bad fakes… So I decided to go for something more reliable.
I also have tested the soshine LiFePo but they had a low capacity…

I thought you were just asking if there were batteries with > 900 mAh.

Here’re onr that I’ve used:

AW 750 mAh, protected:

There isn’t a very wide selection of choices when it comes to 14500 The Nitecore listed above is probably best I seen so far, but I use the trustfire flames, just because they are better value, listed as “900mah” but actual capacity is around 650mah

Sanyo 840mah cell is the highest capacity 14500 that I know of. A high quality cell.

Zebralight has a good 14500. Not sure what cell is on the inside though.

Sanyo UR14500p 840mah are the highest capacity I think. The zebralight branded ones and these: http://intl-outdoor.com/2-pcs-sanyo-ur14500p-840mah-protected-battery-p-... are the only protected versions that I know of.

The Nitecore and AW 750mah ones are the next best I think.

^After reading posts like that one, I wonder why I keep posting links to discharge graphs. What is your "I think" based on? The name and the high prices?

Nitecore, Keeppower, Enerpower, Intl Outdoor, Zebralight all use Sanyo UR14500P and are superior to the one from AW.

If so then why is the Nitecore listed as 750mAh and the SAnyo 840mAh?

Ha ha no, sorry to offend you. I am frustrated by incomplete or misinformation as much as anyone. It was actually based on what I remember from discharge tests and some other info, but it could of course be incomplete and not based on all the facts.

In my post I did actually mention Zebralight, Intl-outdoor (and keeppower by association as intl-outdoor cells are keeppower OEM but I have never seen keeppower 14500 at retail), as better than the Nitecore and AW cells. So from your post the only one I missed out was enerpower, which aren’t all that common..

Where did you get info to suggest that Nitecore 14500s have 840mah UR14500p inside? They are only rated at 750mah like the AWs..

Btw, I have an AW 14500 and it only cost me $7.50 a year or so ago. So the price was actually lower than any of the others bar Nitecore at fasttech! Much cheaper than enerpowers..

If no one posted which brand of cells contained the Sanyo UR14500P how would you know which one to buy.
The I think comes from what we have seen and remember from the past, A newer higher capacity cell could have come out between the last time I checked and today. So I think means, it was the last time I looked.
And don’t forget the Orbtronic 14500. It contains the same UR14500P Sanyo cell, the wrap and pcb (and price) being the only difference in all the UR14500P cells listed here. Smile

OP now you have a whole list of cells to choose from, with the 840mah UR14500P cell. Its always good to know which brands contain the best cells. One of them is always cheaper even though its the same cell inside. :bigsmile:

Out of the 14500's I have (KeepPower and Trustfire), the Nightcore's are by far the best.

I like to use IMR 14500 batteries for flashlights that pull more than 2A.  I find that although IMR batteries have lower capacity, it remains in regulation longer than the regular lithium ions.

Yeah it does, I wasn’t contradicting you, just pointing out that in this case even the wrap and PCB are the same.

Btw Nightcrawl, I have to admit that I’ve only just checked out your link. You’re right, it does look like the Nitecore cells are about matching the UR14500p based ones. Very interesting.

These are 1200mAh …but don’t believe it! Wink Wink

You cannot always go by the advertised rating, look at some reviews, tests and graphs like this one: Test/review summary for small batteries

For me it’s a bit intimidating to try and understand all of the technical data in the tests/reviews/graphs but from what I can tell these Keepower did good in the testing linked above, and are a good value at around $5 each (if you can use 4 of them). I’m thinking about getting these.

Keeppower 14500 are now available from doingoutdoors (but not, alas, to the UK, Germany etc etc).

Interesting that the label on the Nitecore 14500 packaging claims “Made in China”, but that might just be the printers. Big Smile

Thanks for pointing out those keeppowers at doingoutdoors, they would be my pick as the best option. I’ve sent bill an email asking for clarification on shipping (or not) to the UK/Germany. I didn’t think we had any bans on li-ion?

Let me know what his reply is – I’m interested too. I didnt think we had a ban on these either – I just got some 18650 from Hong Kong (FastTech) a couple of weeks ago…

edit I just emailed Bill as well.

The Post Office over here has had restrictions on Lithium cells for a while now. 7Dayshop stopped shipping them for a while, and now will only deliver by courier. Obviously courier delivery is much safer than regular mail. :~

Didn’t stop Fasttech shipping me some Nitecore’s recently. Bill has also had the restriction in place for quite some time – since before his own web site opened up.
