[Elecraft] NiMH batteries How do I test?

[Jim GM]

TNX FOR ALL YOUR INPUT ON THIS.

I found that by running the radio until the 8.5V limit is hit on the KX3
and it shuts down I took out the batteries and tested them on a Radio shack
battery tester that I had,  I let the thing load the battery and watch for
the reading drop.  All cells held their voltage and found one bad cell that
the voltage was lower than the rest and fell like a rock under the load of
the tester. Key thing here is leave the meter test the battery for around
10 seconds or so.

Now replaced bad AA cell re charged, For 16 hours. Battery voltage came up
to 11.4V. Tried to recharge for another 4 hours and the KX3 shut down.  Why
did it do that?  I thought 12 volts is where Max charge.  Is the some sort
of algorithm it goes thought to determine if the cells are fully charged??
