rescued robosapien and roboraptor not working

My friend had a robosapien and a roboraptor in her attic for the last 10 years (guessing). The remotes both seem to be fine but the robos aren't working at all. They both had batteries in them the whole time and the robosapien had been left switched on so the batteries were seriously corroded along with the springy parts of the (-) terminals. I put in new batteties but he won't respond to being switched on or to the remote. The roboraptor looks fine in the battery compartment but doesn't respond at all either.
I just need to know whether it's at all possible to fix these or are they now only good for spare parts?
thanks :-)
