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?
