Yes, this is how I usually do it.

One thing to consider is that normal NiCd Batteries must be charged at 1/10 of their capacity for 14 hours. There are "quick charge" variants, but unless you are sure that yours are of that type you should stay low on the charging current. Otherwise they may last only a few cycles.
