The Ultrafire 1-2-3 are new , as is the AW 2600mAh [7] and the EagleTac [6] .

Im going to start with Max capable discharge rate , I will use 3 different flashlights , MTE SSC P7 , Solarforce L2 R2 , and a Luxeon K2 TFFC ..

For the power curb/run time , it will be the MTE as it has the greatest power consumption ...

So what I will do is throw the batt in the charger , wait for the green light , then let the batt rest for 30 minutes and then test how much current or amps it can deliver to the flashlight ..
Power delivery is probably only going to be of interest to those who are looking for seriously high power applications such as MC-E or SSC P7 , maybe ?











In the first graph , there is no result for the Ultrafire no1 batt as it did not fit the flashlight body , actually 4 batts didnt fit , but Im currently waiting for the EagleTac to charge up [ Came in the post today ] ...Dang , just noticed .. mAh should be Amps ...FIXED !!!










Ok , that takes care of the current test ....

SSC P7 Test , Highest to lowest ...

1. AW-IMR 2.97A
2. Trustfire 2.83A
3. UF no1 2600mAh Protected 2.67A
4. AW 2600mAh Protected 2.66A
5. Generic Blue 2.65A
6. UF 2600mAh no2 2.6A
7. UF 2400mAh Protected no4 2.45A
8. UF 3000mAh Protected no3 2.33A
9. Spiderfire 2400mAh Protected 2.3A
10. EagleTac 2.25A

The Cree R2 Test

1. Generic no 9 1.44A
2. Trustfire 1.43A
3. AW IMR 1.43A
4. UF no1 1.4A
5. UF no2 1.37A
6. AW 2600 1.34A
7. UF No4 1.32A
8. Spiderfire 1.24A
9. UF no3 1.2A
10. EagleTac 1.2A

Sorry the graphs for these are gone ... But listed is the current each battery delivered , SSC P7 and R2 .


Batt No1-Ultrafire 18650 Protected 2600mAh 3.7v + No2+No3+No4+Spiderfire


No1 = As near as I can tell I burned through 2200mA
No2 = As near as I can tell I burned through 2300mA
No3 = As near as I can tell I burned through 2300mA
No4 = As near as I can tell I burned through 1600mA
No5 = As near as I can tell I burned through 1500mA

Half way folks ... and


EagleTac No6 + AW2600 +AW IMR + No9 + Trustfire


No6 = As near as I can tell I burned through 2100mA
No7 = As near as I can tell I burned through 2200mA
No8 = As near as I can tell I burned through 1400mA

Picture host problems again !!!

heheh,

:singing: that ultrafire 3000mAh is going to fall flat on its face!!

(watch out for heat.)

That 3000mAh Ultrafire won't do well at high rates.

It's been shown to only have decent capacity at low discharge rates due to high internal resistance.

Yep , no surprises there ... Be interesting to see the run time though , and could still be a good batt in multi batt flashlights .. Could be ...

I say the AW 2600 comes out on top.

18650 - Next ill do the runtime test , this is going to take a while ...
:wave:

Ultrafire No 3 = Ultrafire 18650 Protected 3000mAh 3.7v
What a grueling test , as near as I can tell , the MTE sucked some 2300mA from this battery .. But look at that run time curve .. 120minutes , and all of it usable light , I dont see there being another 700mA in reserve , so Im calling it quits after 120 minutes ...

Wow , we are half way , Ultrafires tested as was the Spiderfire ...

Well , those spiderfire 18650 are no way near as good as the CR123A's , I just dont know what to say ,

Dare I say , :toilet:

EagleTac / AW's / Trustfire / and generic tests to come ...

Picture Host seems to be having Problems

Too bad about that Spiderfire 18650.

I was hoping we'd see another surprise like the Spiderfire 16340 cells.

Just about every 18650 test I have seen ranked the AW and gray trustfire very high.

thanks so much for doing this test:twothumbs

Do you think its merely coincidence that overall the unprotected cells outperformed the protected cells with the higher current SSC-P7 and XR-E R2?

Could there be a correlation between the protection circuit and the cells ability to deliver higher current?

The protection circuit, upper limit, may be cutting in, not allowing a high current draw from the cells. AW had this problem initially with some of his protected LiIon's and had the protection circuits modified to handle higher amp drain, particularly in the 17500 format.

OK Done ! Interesting results ...

Just need to buy some batts ...

Do any of the American internet retailers sell the Trustfires?

How have the Eagletacs fared safety-wise?

Wow interesting. What happened to the 3000 mAh ultrafire?

Click to expand...

Higher internal resistance.

Works well on lower current draws, but falls on it's face at higher draws.

:thanks:

Maybe I'm missing it....which batts didn't fit in which lights?

Thanks!

Greetings,

Apologies for this question but I just need to confirm as I'm not thoroughly sure about the charts.

For a single 18650 high drain (about 2700 mah) MC-E light, what brand/model would be best?

Thanks,
Moses

Sorry , charts are gone !

The picture host I used was shut down , seems some one decided it was a good host for there porn .

SO there gone .. I also cleaned my HDD , so cant replace them ..

I have the data written down some where , so I will share that ASAP .
