I am having a bit of a problem finding the maximum discharge of a battery. This maximum discharge occurs when the battery is shorted out with such a low resistance wire that the limiting factor becomes the chemistry of the battery. The battery in question is **broken link removed**. Wikipedia says that AA sized NiCds can reach up to 18 amps discharge.
I put my multimeter on the 20 amp range, switched the leads to the correct unfused slots and tested it. It produced 4.5 amps for 15 seconds without getting appreciably warmer. I was very disappointed by this poor performance but I thought I would do a few more tests just to make sure. I then tried a 14 AWG wire and the battery become hot to the touch in four or five seconds. This leads me to believe that the resistance of my multimeter is too high for this application. I will not be able to buy a new one.
Do you guys know of an alternative ways to test this?
