[Test-Equipment] MAHA battery cooker

[Dick KF4NS]

Thanks to all for the input.  There must have been some real problems 
with the PLUS version. Looks like they just replaced them with the 
PLUS II for anyone having a problem.

I too prefer to just let them slow (trickle) charge at the appropriate 
charge rate for the suggested time and they last longer.

Over the years I have had a real mental problem wondering why battery
charging for NICADS and Nimh batteries had to be so involved. I use a 
lot
of battery powered devices (mostly 2-way radios) and all I have ever 
done
is charge them with a power supply and current limiting resistor at 
the
standard 16 hour charge rate (1/10 the amp/hr rating) and I have never 
had
a problem. Sometimes, if I want to keep one topped off, I leave it on 
what
I call "super trickle" which is 1/10 of the standard charge rate.
