Ni-Metal Hydride Battery Chargers

Now that Ni-Cad batteries are becoming an endangered species, is there any way to convert their chargers to work on the newer and ecologically sounder Ni-Metal Hydride batteries? I read that the Ni-Metal batteries have very different charging requirements rather than the constant current chargers for Ni-Cads. I have several bench chargers, not to mention a multitude of “wall warts” that I would like to modify.
