AA Battery capacity tester- resistor & clock

I've got a couple dozen Nimh batteries that are starting to show signs
of age. [some are 7yr old 800mAh, the newest are 2000 mAh & 3-4 yrs
old]

I googled for capacity testers and found a post that said to wire a 1
ohm resistor in series with a aa battery operated clock. Set the
clock to 12, insert battery, wait until clock stops.

I have a box of clock parts so I set up a 4-battery tester and set it
in motion yesterday with some of the 2000 mAh batteries.

Did I wire it wrong, or did I miscalculate how long it should take to
discharge a 2000 mAh battery? At 25 hrs, 45 minutes we're still
running the clocks.

The resistor I used is a Radio Shack- 1.0 Ohm, 10w. - part #271-131.

I connected one end of the resistor to the positive end of the
battery, and the other to the positive terminal in the clock, the
negative end of the battery to the negative terminal on the clock.

Thanks,
Jim
