There is no such thing as a battery that is safe after 30 years! Even if it still seems to charge up and work, you should at least make sure it isn't leaking electrolyte and corroding the traces near it.
You want to replace it with a new nicd or nimh battery. The reason he tried a capacitor in place of a battery he can say for himself, but to me it was a reasonable and interesting experiment that would have been pretty neat if it worked. It might still work with merely some further adjustment like add a diode to drop the voltage or something. I might have tried that myself because some kinds of capacitor are much longer lived and safer than any battery, because they are dry, solid state parts with no electrolyte to leak and no chemical reactions like what happens to plates in batteries.
