You have to be carefull though. NiCD is usually charged either at C/10 rate
of at high current, where a drop in voltage is used to detect the end of the
charging cycle.

The C/10 charge with NiCD cannot overcharge them.

However, NiMH batteries show a much smaller voltage drop when full, which
might not be detected by a fast NiCD charger. Also, overcharging NiMH at
C/10 will certainly damage them. So be careful!

So for routine purposes and otherwise healthy NiMH cells, what would you
use? As an aside, I finally figured out that C/10 means 1/10th of
capacity and that C/20 or C/30 is a much better idea.

I have a DuraCell quick charger that is identified as a "Class 2"
charger but does not tell me much more than that. Do you know what the
charge rate on a Class 2 charger is? Output is 1.6V @ 1800mA.

I'm about to throw away the DuraCell and get a Maha I think.
