Provided they have been discharged to their specified discharge voltage
before.
Which in 99 out of 100 cases they haven't. It's not a good idea to charge
batts that are only partially discharged that way.

It also gets hot when it is just fine and healthy, but currently being
overcharged.
Fully charged NiCads turn most of the charge current into heat.

Which isn't at all required to make the batts heat up if overcharged.
That's why Apple built in the thermistor ;-)
