I also did your short circuit test

Nicad 500ma
Alkaline 300ma

As you can see, it far from puts out the max current of the AA's.
Okay, let me give an EXACT detail of how I got my 2A+ readings and let's see what I'm doing wrong...

This is my DMM (from the shack):

When testing:
1. I take a standard Bit Tx/charger and turn it on (this is with Alkalines)
2. With the DMM set to test in the Amps range (have to switch the red lead to the 10A max plug) I put the leads onto the prongs of the charger
3. I get readings in the 2.2A to 2.5A range

With the red lead in its' usual plug, it has a max range of 400mA...I've already blown a fuse trying to test in this range and learned my lesson there.

What's being done wrong?
