Using nicad AAA batteries in the HP48 will work just fine,
however they have somewhat less capacity than alkalines.
Only one little thing to watch out for:
Alkalines have a roughly linear discharge curve.  This 
means that when you use alkalines and the low battery
indicator comes on, you have a relatively long time
(depends entirely on your type of usage - a few hours
for heavy run with IO to several months with no use
at all) to change batteries.  Nicads, however, have a
rather sharp knee in the discharge curve.  Once they
hit the low battery warning, time is of the essence
(again, your mileage will vary...).
