Test / Review: TrustFire TF26650 5000mAh (Flame)
TrustFire TF26650 5000mAh (Flame)

I have tested this battery from two different sources.

DSC_1065

Official specifications:
  • Brand: TrustFire
  • Model: 26650
  • Voltage: 3.7V
  • Capacity: 5000mAh (actual 4000mAh)
  • Rechargeable Li-ion battery
  • Built-in protection circuit
  • Great batteries for your flashlight or other devices
  • Dimensions: 2.68 in x 1.02 in x 1.02 in (6.8 cm x 2.6 cm x 2.6 cm)
  • Weight: 6.38 oz (181 g)

TrustFire%20TF26650%205000mAh%20(Flame)-info

Notice the difference in weight between the two tested batteries.
The charts are not using the same scale as the 18650 charts, due to the higher capacity of this battery.

From DX it is the usual envelope.

TrustFire%20TF26650%205000mAh%20(Flame)-Capacity

They have slightly different capacity, but not much. With the weight difference I had expected more difference.

The two batteries has a different current limit, it is not easy to see on the chart, but one trips at 6.9A the other at 7.6A.

DSC_2090

Official specifications:
  • Operating voltage: 3.7V
  • Capacity: 5000mAh
  • Ultra-high capacity and premium built quality
  • Protected to avoid over-charged or over-discharged

TrustFire%20TF26650%205000mAh%20(Flame)%20man-info

These two batteries did also have a weight difference. They are also slightly longer than the DealExtreme version.

I did only get one battery per envelope, because I ordered them one at a time.

Conclusion

This battery has about 30% more capacity than a 18650, but about 100% more volume, without being able to sustain more current drain. But it does keep a higher voltage than any 18650 battery under load.
The battery has less capacity than stated on the cell.

For a cheap battery it is acceptable.

The Manafont version are slightly better than the DealExtreme version, I cannot tell if this is random variations or not.



Notes and links

I have added the battery to the 18650 comparator, this makes it possible to compare voltage at different loads.

I just happened to be processing all of your previous reviews at the same time that you submitted this one. Very nice work sir.

HKJ, you must be a mind reader!  I was just thinking how cool it would be to have a tool to select batteries to compare output charts and you've created one!

AWESOME!!

Thx a lot for this review and the new comparo chart, what a great service to the community!

Were there any other indications or markings to potentially differentiate the two cells?

Thanks again for the well-presented review.

This batteries aren't supposed to be fakes? I thought the ones from MF was genuine

I've got a pair of them coming from CNQG, it is good to know they are 4000mAh being protected, and being able to give about 7A.

Compared to the one benckie tested, these looks better. They have higher voltage during the 3A discharge. This might also be due to resistance in benckie's wires and magnets, the voltage difference is about 0.1 volt, only 0.03 ohm is needed for that at 3A.

With the photos I have posted benckie or anyone else that got these batteries from Manafont, can probably tell if there are any difference in the wrapping or construction.

Yeah i think my main charge leads, soldering and the rare earth magnets might make a slight diffrence, but still good for reference as 0.1 volt is not much.

Im not confindent DX will maintain sending out good cells and it might end up like the trustfire flame 18650,s they where selling.

The cell i tested i belive is a 100% geniune cell, i have pulled apart the cell to confirm, to see pictures of the cell i tested and striped look here (Manafont cell not DX)

I do like to get it included, that was the reason I did my setup with separate measuring wires.

I do believe that both DX and Manfont did change to a worse 3000mAh battery.

And it might have higher capacity than the DX one, at least you measure more capacity that I do.

It is interesting to see the pictures of the PCB protection.

Yep! Thanks both HKJ and Benckie for their work. Really liked the discharge tests showing 4500mah!!

Just a thought between the DX and manafont version:

It seems like Benckie's battery (pic above) from manafont has a hologram sticker below the negative symbol, whereas HKJ's DX doesn't (Opening Post).

What is the deal there? Hmmm..

I just got 4 of them with my TF X100 order. Randomly picked one of them and got 4196mAh @ 1A discharge down to 2.8V, 1st cycle.

Looks what a strange shape the plus pole has now compared to older pics in the thread, sure something is different in this new batch! Better or worse cannot say without testing, but sure they aren't the same they were before.

Just took delivery of two trustfires from ebay seller £10.88.and two from amazon £13+.
when my bt-c3100 charger arrived i decided to capacity test them just to make sure they are all around 4400mah.
To my amazement they are all 5000mah+….5166,5149,5208,and a shocking 5360mah.
not sure which battery came from where ,but if my charger is working correctly this would indicate trustfire have upped the ante on battery capacity/value.! not sure how to add photo,s but rest assured i took some .and will happily email attach.IMGP0737!

Greetings Darkness,
I thought I was losing it here.
Just picked up a pair of TF 26650’s from E-Bay for $15 delivered.
Charged and tested drain 2x with my iMax B6.
I ran 2 charge up and down cycles then did final tests on both.
Capacity was 5427 & 5398mAh for the 2 batteries at 1 amp draw down to 3.0v.
I thought my B6 was off….
I do have pics of the charge results I can try to get up, or I can E-Mail.
Cheers

added item 2-3-15: I noticed that my tested was stopping at 330 minutes. Found a cutoff timer was stopping test before complete. Changed timer to 360 minutes and capacities went up.

Added I-Max B6 discharge test pics with 360 minute timer:

yeah, which item
I’d expect 500mAh from ebay, not over 5000.

I was really expecting something in the range of 4000mAh for these, but ran them 2x each through my B6 to test.

Thanks for the seller info. On the strength of your post, very tempted to get a couple hoping for a long run time in Yezl Y3 — for night time hiking.

I was wondering if you tried them in a flashlight beside your two discharge/charge in the iMax B6.

[EDIT]
Drew blank when searched for the ebay seller:byttmallzone365 .

[EDIT2]
Your item was delivered … on November 29, 2014.
Long time ago.

The best price now is $16.74.

I’m also a little tempted! BLightSam means to say that the seller is “ttmallzone365”.

@ BLightSam: What discharge currents have you tested at? [I doubt your usage experience will tell us much since you just got them…]

Still fine, still on a break. One day I’ll catch up with you folks! previous wight catchup Wink

This thread and it's info is over 2 years old. A lot has happened since then, but basically, anything with fire in the name is still not likely to be the best to buy, nor will in necessarily be trustworthy. There are plenty of good cells sold by dealers like Mtn Electronics, (RMM), and Illumination supply, but you won't see Trustfire on their web sites. They are just not good batteries to have faith in, since they are inconsistent and copied so much. Some are even used cells, that had new labels put on. Happens all the time. I try to stick with cells from well known and respected sellers.

Greetings O-L,

Most of the time the “Fire” suffix means ‘danger’, indeed.
However, I personally have not had any of apx 18 total, Trustfire batteries be any less than I expected. Most of them are 14500’s, with 2 – 18650’s and now 2 – 26650’s. They have all done very well, at a reasonable cost.
Buying from seller with good history is a good place to start any purchase.
Cheers,
