Minor thread hijack.

I just got a couple of Baofeng UV-5R H/T radios.  (I'm sitting for my 
Technician license Saturday).  They come with Li-Ion batteries which 
seem to last a LONG time.  I also ordered an AA battery tray for them so 
I could use AA batteries in an emergency.  Can the factory charger, 
which is set up to charge Li Ion batteries, also charge NiCads or Nimh 
batteries if I stick the AA battery tray in the charger?
