First 5 Batts tested : [ 1 to 5 ]



2nd set of 5 [ 6 to 10 ]




:popcorn:

OK did some calculations :

Flea Bay batt pushed some : 676mA to the 30 minute mark .
Spiderfire Pushed some : 619mA to the 30 minute mark .
AW did some : 620mA Give or take at the end , depending on just when it became depleted .
KD = some 545mA
Solarforce = 544mA

584_powercurve.jpg




Trustfire = 513mA
DX = 342mA
Ultrafire No 8 = 528mA
Ultrafire no 7 = 590mA
Ultrafire Flea Bay No 5 = 535mA






OK there we go : Power curves included .

In order of Tested capacity to 30minutes = over 600mA
1/ Generic Flea Bay [ ?? ]
2/ AW
3/ Spiderfire

Over 500mA
4/ Ultrafire No 7 [ This is the one they claim 1000mA ]
5/ Take your pick = KD - Solarforce - Ultrafire or Trustfire , all just over 500mA

Over 400mA

Over 300mA
6/ DX battery , ??? Dont know what to say ...

i just spent 2 days trying to test my little spare ultrafire things, they are one year old, and on your device there , they would get about 5 minutes , i dont think i am going to chart them :)

i see your #4 has a most rescent date on it, cool, it would be interesting to see what it does in april of 2010.
mabey they should all be marked with date like bread and meat. (use before next week)

Very interesting. Price seems to vary widely, while performance is closely contested.

With the exception of #9, all these batteries were fairly comparable in your test. Unless the physical dimensions posed a problem on some of the protected cells, this result would lead one to go for the bargains (except #9).
 
Yeah , No9 did really flop big time .. I was expecting more from this batt , but there you go .

And the big surprise was No4 . I was taken aback by its performance , esp after hearing so much negativity towards anything flea bay .

Oh well ! I might try and work out how much was sucked out of the batts next ...
 
I cycled 8 pieces of #9 for capacity and the best was only 320mAH and the worst was 275mAH. :thumbsdow

Using the OP's data, here's some expanded Excel info on RCR123's I own, hope it's self explanatory.

They are the generic Ebay 3.7volt batts often bundled with a charger . and 1000mAh claim ...

Mine came from here : stores.ebay.com/cwtco

Interesting... the size on that battery is 17335. I've never seen that before. I wonder if that extra mm of width gives them just a hair more oomph?

Interesting how the photo in their ebay listing for that purple battery says 16340 but a 17335 was tested here. =)
Also, from what I can see, they are selling 4 of them for 1GBP + 3GBP shipping. Equates to $1.50 a piece.

Matt, can you tell us which ones are protected and which aren't?
As I myself would not be using non-protected with most flashlights. =P
 
And the eBay description mentions 17mm x 33.5mm... hmmmm even though it says 16340 on the cells pictured. :thinking: Had to order 4 just to see what was up.

However, don't buy the WF CR123's sold there, there are absolute rubbish .

Yep ! I purchased the 4batt Charger combo , and got what I got ..
They were not the same as pictured .

Look at the green 3volt rechargeables there [ flea bay ] , the only ones I can find that are marked 17335 ..

For 3.7v if the pictures are current ???
BL-ICR123A 1000mA
LC 16350
TR 16350
ICR 123A
FL 16340
LIR123A - Dont recommend = No 9 if there what DX sells .

Here is a clean picture in anyway :



I found the email for the purchase : And pictured were the TR 16350 Batts + Charger ..
