What is currently the best value in 18650 batteries

I need to buy 4 more, and have not kept up on 18650 threads lately.

Not interested in spending $10 per battery, looking for reasonable quality at a lower price point.

Protected cells are preferred. Thanks

Rats, finally sold my 2010 509hp Mustang...now I can buy more lights!

Sold the red one too! Now guess what I drive, doing my penance for 500 hp commuters...

Trustfire 2400mah flames. 

I have been buying mine for around $8 a pair shipped lately.

I thought the first Trustfire 3000 from Manafont tested good @ 2600mah but the ones purchased later only tested 2000 or 2100 mah or so. This was a recent thread from BLF and a reason I didn't order any.

EDIT reread the thread 2100 to 2300 mah.

The best value are the Sanyo UR18650F/M. They have consistent results, unlike the Trustfires.

To get those protected you have to buy the XTARs, or the Sparks.

One interesting aspect of Trusfire cells, that has not been tested yet, is if the capacity reduces randomly in time (not all cells loose the same capacity) in the same way they seem to be made with random capacities. Probably cells the cells are not "binned" as LEDs by CREE for example.

Arent Senybor also Sanyo based? Edit: actually it seems they are coy about this info but removing the wrapper has shown Panasonic apperance.

This guy is a seller but I have no reason to not trust his results:

I do not know what are they based, I only know they are made be a Chinese company in Shenzhen.I know that in UK there's a lot of buzz with Torchies cells. Well that is primarily because of all those 1A comparisons he did. He says 1C  discharge and then the discharge is done with 1A, Then at 2C the discharge says 1A also. If you look at the graphs there's no voltage sag...... Actually the sag is lower on the 5.6A discharge, which is not possible.

I haven't bought high quality 18650s for a while.  Are these HI-MAX batteries still a good value?

Hmm, I have some more Senybors now and really should get round to doing some more tests but in my tests they outperformed the @&£)fire cells. I will get the internal impedance tester on them also.

If you might consider unprotected, I've been looking at these for a while, Sanyo 18650 2600mAh from Intl Outdoor, at $5.85 a piece. Free shipping if bought 3pcs above.

Its brother (2100mAh) has been tested to get 1800mAh, around 85% of claimed. Since it's Sanyo cell, I believe that result will be consistent, and for a 2600mAh cell, good chance you will get a good 2200-2300 mAh from these. Still a great value for the price.

No, they are the real deal. They have a US and China warehouse. After reading the bad reviews, I decided to risk and purchase them. So far I've had good experiences with Pandawill.

I recently had a DX Trustfire Flame go bad on me. Not in a bad way, it just wouldn't charge up anymore. I'd probably had it for a couple of years, but not real heavy use. So I bought some more XTAR 2600's from the longstanding group buy. I think those are very good batteries for a little more than Trustfires. Still a lot less than AW's and equivalents.

I have 4 TF 3000 soon here, wait a while before ordering. Quality may vary, going to test them... Xtars with groupbuy price are the safest bet.

I can recommend the TF Flames from Manafont. I've bought about 100 of them in the past 3 months and I only had one that was DOA.

I think you're safest with the XTAR 2600 at $13.50/pair from Serena or I guess even that Pandawill site if you're feeling lucky. That's all I've been buying lately, for myself and for friends.

I have had good luck with HiMax 2600's in the past but they seem to have gotten very expensive.

I have over 50 Trustfire flames from DX some over over a year old all of them still work. The ones I have tested all had decent capacity.

I am already visualizing the duct tape over your mouth.

massive discharge rate, low resistance, not going to explode

imo, they're the best value, hands down

They might not be the cheapest but I just ran some testing on these in a light that draws high amps and they truly are outstanding!  Definitely more capacity than the AW IMR's and as long as your application is below 10A then you should be good.

I also used them as a pair in the EYE30 runtime testing and they yielded just slightly less than the AW 2600's:

Those are great cells.

I acquired an identical one from Callie's, and it allows for more current in my Direct Drive SST90 than my AW IMRs by over a quarter Amp. (~280mA)

I will slowly but surely be replacing all of my IMR 18650s with these.

 

A very good cell at a fair price is the Sanyo-based Solarforce 2400 protected 18650.  The wrap is a bit brittle, however.

no but I think callie's sells them re-wrapped w/ protection.  They are safer chemistry cathode, despite saying li-ion on the side, so for my purposes, the protection isn't relevant (I don't drain my cells to where protection trips....on purpose anyway).

I'll also back the Sanyo-based Solarforce 2400mah. Indeed, the wrap is brittle, which is the only downfall. Otherwise they are quite the performer for the price. They seem to match my XTAR 2600's.

What about cycle life & shelf life? I'd guess they would be quite high due to low initial internal resistance (isn't it's increase the cause of cell degradation?)

These were, AFAIK, designed for use in high-draw rechargeable power tools.  Since both criteria are important design considerations, I would infer that both would be excellent - why bother changing chemistry otherwise?   Pricing is similar, if not greater, than common lithium-ion cells.

The sample that I own has performed above expectations over the last 9+ months.

can't say for sure, only a few cycles

but, I would assume that a cell that can do 10A discharge (at very close to stated capacity!) will handle 3 and 4A discharge for a lot longer than cells that are struggling when they do that?    Now...that's not very scientific...but it made me feel better about spending $9 on a battery lol

the other thing to note w/ this cell, is that for some lights, it has more usable capacity than the mah alone implies - check out the tests/graphs done on this cell, and the voltage level that it maintains during discharge...a couple members (hkj and mitro?) were kind enough to share data of some thorough testing.

..I'd also guess that it would charge faster at amp same rate due to more time spent in CC phase and less in CV phase?

(I might be wrong on this one though, correct med if needed please ;Ь)

I vaguely recall the charge rate spec is lower than similar cells - but someone probably knows what it is off hand...

I use 1A setting on my hobby charger, or an xtar mp1

HKJ has a roundup of 18650 batteries at CPF with a lot of good data. He's not finished yet, but there is a lot of good info there.

http://www.candlepowerforums.com/vb/showthread.php?330236

Cheap way to measure capacity? You can get a rough estimate by measuring current draw in milliamps on a flashlight at a regular intervals like 10 minutes until you get down to whatever cutoff voltage you want. 10 minutes is 1/6th of an hour, so you total all of the current readings and divide by 6 to get mAh. You will have to average the initial and final reading or you will have one reading too many.

If you get a hobby charger you can do it, but mine will only do a maximum discharge rate of 1000 mA.

If I needed more 18650 = Sanyo

I know there not protected , but Im ok with that ..

There were some really nice prices a little while ago on the 2600 ..

I have some of the Trustfire 3000 that I bought a few months ago.  They seem to be good and hold more capacity than my other less expensive batteries.  I just ordered 8 more from MF the other day.  I hadn't heard that some are having problems with newer batches.  Hope mine will be ok.

I recently bought some 2900mah unprotected panasonic NCRs from focalprice.  I think they are ~$7.50 shipped.  If you buy more than 3, then it starts getting cheaper.  I just received it the other day... running some tests on them and will start another thread and report back when done.  But here are a few quick figures for you:

-arrive at ~3.64V

-charged up to ~4.16V

-Discharged at 200ma, until it reaches 3.0V (low cut off for my acucell 6).  Gave 2749mah.  Resting voltage after test 3.19V (this means there's still juice left in the battery, as the ncr18650 can be discharged to 2.5/2.75V).

My only concern with these batteries are the middle of the battery bulges out very slightly.  Probably not a good sign?

Try using a caliper to measure the difference , diameter towards the ends and diameter on the bump. Also you can check later if the "bump" diameter has increase with use or not.
