First 5 Batts tested : [ 1 to 5 ]

2nd set of 5 [ 6 to 10 ]

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

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 ...
