[Elecraft] NiMh batteries How do I test?

[KB9WMJ at wi.rr.com]

Measure the amps you are charging them with, and charge them at C/10, where
C is the capacity of them.  Say you have 1200mA NiMh batteries, charge them
at 120mA overnight.  You can charge up to C/1, but be careful not to
overheat the cells.  You should be able to hold them in your hand.

Then put some sort of a load on the batteries, and measure the voltage on
each individual cell.  As they discharge, the weakest cell will drop in
voltage faster than the rest.

I have 8 NiMh batteries and charged them for 16 hours.  Charge lasts 5
minutes before KX3 goes dead. Minimum voltage is set for 8.4V. with a 13.6
volts 50 amp DX Astron supply max charge voltage get up to 10.6 VDC says my
KX3. When checking the voltage independantly on each cell they all give me
the same reading on my battery tester saying they are good so the tester is
full of it.

How do I test these cells for find my bad one or 2?
